-## Setup
-
-Add Voucherify dependency into your `composer.json`:
-```
-"rspective/voucherify": "v2.0.*"
-```
-Update project dependencies:
-
-```
-$ composer install
-```
-[Log-in](http://app.voucherify.io/#/login) to Voucherify web interace and obtain your Application Keys from [Configuration](https://app.voucherify.io/#/app/configuration):
-
-```php
-require_once('vendor/autoload.php');
-
-use Voucherify\VoucherifyClient;
-use Voucherify\ClientException;
-
-$apiID  = "YOUR-APPLICATION-ID";
-$apiKey = "YOUR-CLIENT-SECRET-KEY";
-
-$client = new VoucherifyClient($apiID, $apiKey);
-```
-
-### Versioning
-All requests will use your account API settings, unless you override the API version. The changelog lists every available version.
-
-```php
-$apiVersion = "v2018-08-01";
-
-$client = new VoucherifyClient($apiID, $apiKey, $apiVersion);
-```
-
-Check [versioning](https://docs.voucherify.io/reference?utm_source=github&utm_medium=sdk&utm_campaign=acq#versioning).
-
-### Custom API URL
-By default client is sending request to `https://api.voucherify.io`. You can override `$apiUrl` while creating client instance if you want to use Voucherify running in a specific region
-
-```php
-$apiVersion = null;
-$apiUrl = "https://<region>.api.voucherify.io";
-
-$client = new VoucherifyClient($apiID, $apiKey, $apiVersion, $apiUrl);
-```
-
-### Custom Headers
-It is possible to send custom headers in Voucherify API request.
-```php
-$apiVersion = null;
-$apiUrl = null;
-$customHeaders = [
-    "X-Custom-1" => "Value-1"
-];
-
-$client = new VoucherifyClient($apiID, $apiKey, $apiVersion, $apiUrl, $customHeaders);
-
-# RESULT:
-#   x-custom-1: Value-1
-```
-
-Special: Voucherify-Channel customization
-```php
-$apiVersion = null;
-$apiUrl = null;
-$customHeaders = [
-    "V-Voucherify-Channel" => "Value-1"
-];
-
-$client = new VoucherifyClient($apiID, $apiKey, $apiVersion, $apiUrl, $customHeaders);
-
-# RESULT:
-#   x-voucherify-channel: PHP-SDK-Value-1
-```
-
-### PHP autoloading
-
-When you aren't using composer you can load Voucherify module by including `autoload.php` file from `/src` directory.
-
-```php
-require_once('{voucherify_src_path}/autoload.php');
-
-use Voucherify\VoucherifyClient;
-use Voucherify\ClientException;
-
-$client = new VoucherifyClient($apiID, $apiKey);
-```

-```php
-try {
-    ...
-}
-catch (ClientException $e) {
-    $error = $e->getError();
+```json
+{
+  "repositories": [
+    {

-VoucherifyClient has method `setLogger()` which can be used to set PSR-3 logger interface.
-
-Set own logger if you want to preview curl request and response data.
-```php
-$logger = /* Initialaze logger i.e Monolog, Analog */
-
-$client = new VoucherifyClient($apiID, $apiKey);
-$client->setLogger($logger);
-```
-
-## Connection Options
+Then run `composer install`
 
-Use `setConnectionOptions()` method to set client connection options.
+### Manual Installation
 
-Options:
-- `timeout` - curl 'CURLOPT_TIMEOUT_MS'
-- `connectTimeout` - curl 'CURLOPT_CONNECTTIMEOUT'
+Download the files and include `autoload.php`:
 
 ```php
-$options = [
-    "timeout" => 1500,
-    "connectTimeout" => 2
-];
-
-$client = new VoucherifyClient($apiID, $apiKey);
-$client->setConnectionOptions($options);

+## `addVoucherWithSpecificCodeToCampaign()`
+
+```php
+addVoucherWithSpecificCodeToCampaign($campaignId, $code, $campaignsVouchersCreateRequestBody): \OpenAPI\Client\Model\CampaignsVouchersCreateResponseBody
+```
+
+Add Voucher with Specific Code to Campaign
+
+This method gives a possibility to add a new voucher to an existing campaign. The voucher definition will be inherited from the definition kept in the campaign profile. However, you are able to overwrite a few properties inherited from the campaign.
+
+### Example
+
+```php
+<?php
+require_once(__DIR__ . '/vendor/autoload.php');
+
+
+// Configure API key authorization: X-App-Id
+$config = OpenAPI\Client\Configuration::getDefaultConfiguration()->setApiKey('X-App-Id', 'YOUR_API_KEY');

+// $config = OpenAPI\Client\Configuration::getDefaultConfiguration()->setApiKeyPrefix('X-App-Id', 'Bearer');
+
+// Configure API key authorization: X-App-Token
+$config = OpenAPI\Client\Configuration::getDefaultConfiguration()->setApiKey('X-App-Token', 'YOUR_API_KEY');
+// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
+// $config = OpenAPI\Client\Configuration::getDefaultConfiguration()->setApiKeyPrefix('X-App-Token', 'Bearer');
+
+
+$apiInstance = new OpenAPI\Client\Api\CampaignsApi(
+    // If you want use custom http client, pass your client which implements `GuzzleHttp\ClientInterface`.
+    // This is optional, `GuzzleHttp\Client` will be used as default.
+    new GuzzleHttp\Client(),
+    $config
+);
+$campaignId = 'campaignId_example'; // string | The campaign ID or name of the campaign to which voucher will be added. You can either pass the campaign ID, which was assigned by Voucherify, or the name of the campaign as the path parameter value.
+$code = 'code_example'; // string | A custom **code** that identifies the voucher.
+$campaignsVouchersCreateRequestBody = {"category_id":"cat_0bb81a481615a37b5e","start_date":"2022-09-24T00:00:00Z","expiration_date":"2022-09-25T23:59:59Z","active":false,"redemption":{"quantity":null},"additional_info":"Voucher added using API","metadata":{"Season":"Fall"}}; // \OpenAPI\Client\Model\CampaignsVouchersCreateRequestBody | Specify the voucher parameters that you would like to overwrite.
+
+try {
+    $result = $apiInstance->addVoucherWithSpecificCodeToCampaign($campaignId, $code, $campaignsVouchersCreateRequestBody);
+    print_r($result);
+} catch (Exception $e) {
+    echo 'Exception when calling CampaignsApi->addVoucherWithSpecificCodeToCampaign: ', $e->getMessage(), PHP_EOL;
+}
+```
+
+### Parameters
+
+| Name | Type | Description  | Notes |
+| ------------- | ------------- | ------------- | ------------- |
+| **campaignId** | **string**| The campaign ID or name of the campaign to which voucher will be added. You can either pass the campaign ID, which was assigned by Voucherify, or the name of the campaign as the path parameter value. | |
+| **code** | **string**| A custom **code** that identifies the voucher. | |
+| **campaignsVouchersCreateRequestBody** | [**\OpenAPI\Client\Model\CampaignsVouchersCreateRequestBody**](../Model/CampaignsVouchersCreateRequestBody.md)| Specify the voucher parameters that you would like to overwrite. | [optional] |

+## `addVouchersToCampaign()`
+
+```php
+addVouchersToCampaign($campaignId, $vouchersCount, $campaignsVouchersCreateInBulkRequestBody): \OpenAPI\Client\Model\CampaignsVouchersCreateCombinedResponseBody
+```
+
+Add Vouchers to Campaign
+
+This method gives the possibility to push new vouchers to an existing campaign. New vouchers will inherit properties from the campaign profile. However, it is possible to overwrite some of them in the request body. If you provide an optional code_config parameter with a voucher code configuration, then it will be used to generate new voucher codes. Otherwise, the voucher code configuration from the campaign will be used. This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+## `createCampaign()`
+
+```php
+createCampaign($campaignsCreateRequestBody): \OpenAPI\Client\Model\CampaignsCreateResponseBody
+```
+
+Create Campaign
+
+Method to create a batch of vouchers aggregated in one campaign. You can choose a variety of voucher types and define a unique pattern for generating codes.    📘 Global uniqueness  All campaign codes are unique across the whole project. Voucherify will not allow you to generate 2 campaigns with the same coupon code.    🚧 Code generation status  This is an asynchronous action; you cant read or modify a newly created campaign until the code generation is completed. See the creation_status field in the campaign object description.

+
+Delete Campaign
+
+Deletes a campaign and all related vouchers. This action cannot be undone. Also, this method immediately removes any redemptions on the voucher. If the force parameter is set to false or not set at all, the campaign and all related vouchers will be moved to the bin. This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished.

+## `importVouchersToCampaign()`
+
+```php
+importVouchersToCampaign($campaignId, $campaignsImportVoucherItem): \OpenAPI\Client\Model\CampaignsImportCreateResponseBody
+```
+
+Import Vouchers to Campaign
+
+Imports vouchers to an **existing** campaign. This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+
+List Campaigns
+
+Retrieve a list of campaigns in a project.  The campaigns are returned sorted by creation date, with the most recent campaigns appearing first.   When you get a list of campaigns, you can optionally specify query parameters to customize the amount of campaigns returned per call using limit, which page of campaigns to return using page, sort the campaigns using the order query parameter and filter the results by the campaign_type. This method will return an error when trying to return a limit of more than 100 campaigns.

+## `checkEligibilityClientSide()`
+
+```php
+checkEligibilityClientSide($clientQualificationsCheckEligibilityRequestBody): \OpenAPI\Client\Model\ClientQualificationsCheckEligibilityResponseBody
+```
+
+Check Eligibility (client-side)
+
+Generate a list of redeemables that are applicable in the context of the customer and order. The new qualifications method is an improved version of Campaign Qualifications, Voucher Qualifications, and Promotions Validation API requests. The new qualification method introduces the following improvements: - Qualification results are returned faster - No limit on the number of returned redeemables - Introduces new qualification scenarios, not available in the previous version  👍 Scenario Guide  Read our dedicated guide to learn about some use cases this endpoint can cover here. # Paging  The Voucherify Qualifications API request will return to you all of the redeemables available for the customer in batches of up to 50 redeemables. To get the next batch of redeemables, you need to use the starting_after cursor. To process of paging the redeemables works in the following manner: - You send the first API request for Qualifications without the starting_after parameter. - The response will contain a parameter named has_more. If the parameters value is set to true, then more redeemables are available. - Get the value of the created_at parameter of the last returned redeemable. The value of this parameter will be used as a cursor to retrieve the next page of redeemables. - Send another API request for Qualification with the starting_after parameter set to the value taken from the created_at parameter from the last returned redeemable. - Voucherify will return the next page of redeemables. - If the has_more parameter is set to true, apply steps 3-5 to get the next page of redeemables.

+
+Redeem Stackable Discounts (client-side)
+
+This method is accessible through public keys which you can use in client side requests coming from mobile and web browser applications. # How API returns calculated discounts and order amounts in the response In the table below, you can see the logic the API follows to calculate discounts and amounts:    📘 Rollbacks  You cant roll back a child redemption. When you call rollback on a stacked redemption, all child redemptions will be rolled back. You need to refer to a parent redemption ID in your rollback request.

+## `importCustomersUsingCsv()`
+
+```php
+importCustomersUsingCsv($file): \OpenAPI\Client\Model\CustomersImportCsvCreateResponseBody
+```
+
+Import and Update Customers using CSV
+
+This API method lets you import or update customer data. To get a proper and valid response, please send a CSV file with data separated by commas.   # Request Example # CSV File Format The CSV file has to include headers in the first line. All properties which cannot be mapped to standard customer fields will be added to the metadata object.  📘 Standard customer fields mapping  **No spaces allowed in field names**    Id, Name, Email, Phone, Birthdate, Source_id, Address_line_1, Address_line_2, Address_Postal_Code, Address_City, Address_State, Address_Country, Description, Metadata_name_1, Metadata_name_2 # Update Customers using CSV If you would like to update customers data, you can do it using the CSV file with new data. However, remember to include a source_id in your CSV file to manage the update successfully. This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+## `updateCustomersInBulk()`
+
+```php
+updateCustomersInBulk($customersUpdateInBulkRequestBody): \OpenAPI\Client\Model\CustomersUpdateInBulkResponseBody
+```
+
+Update Customers in Bulk
+
+Updates customers in one asynchronous operation. The request can include up to **10 MB** of data. The response returns a unique asynchronous action ID. Use this ID in the query paramater of the GET Async Action endpoint to check, e.g.: - The status of your request (in queue, in progress, done, or failed) - Resources that failed to be updated - The report file with details about the update If a customer object is not found, it is **upserted**. This is shown in the report file in the GET Async Action endpoint. The upserted resources have value false in the found column and true in the updated column. This API request starts a process that affects Voucherify data in bulk. In the case of small jobs (like bulk update), the request is put into a queue and processed when every other bulk request placed in the queue prior to this request is finished.

+```
+
+Import Orders
+
+🚧 Historical orders  This endpoint should only be used to import historical orders into Voucherify. For on-going synchronization, the create order and update order endpoints should be used. This is critical because this endpoint does not store events or launch distributions. # Limitations ## Import volume There can be only a single on-going order import per tenant per project at a given time. The user can schedule more imports but those extra imports will be scheduled to run in sequence one by one.   ## Maximum count of orders in single import There is a 2000 limit but we might decide to change it to a lower / higher value at any given time depending if we find this value is too high or too low with time. # Notifications There are no notifications on the Dashboard because this import is launched via the API. # Triggered actions    If you import orders with customers, then a logic will be scheduled responsible for placing these customers into segments and refreshing the segments summary. Consequently, this update will trigger  - **customers entering into segments**  - **distributions** based on any rules tied to customer entering segment(s) - **earning rules** based on the customer entering segment(s) # What is not triggered 1. No webhooks are triggered during the import of orders - for both orders and upserted products / skus.   2. Distributions based on Order Update, Order Paid, Order Created and Order Cancelled. In other words if you have a distribution based on Order Paid and you import an order with a PAID status, the distribution is not going to be triggered.     3. No events are created during the import of orders - for both orders and upserted products / skus. In other words you wont see any events in the Activity tab in the Dashboard such as Order created or Order paid. If you are additionally upserting products / skus, then you wont see the Product created events listed, etc.    4. Earning rules based on Order Paid wont be triggered. This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+## `importProductsUsingCsv()`
+
+```php
+importProductsUsingCsv($file): \OpenAPI\Client\Model\ProductsImportCsvCreateResponseBody
+```
+
+Import Products using CSV
+
+Import products into the repository using a CSV file.   This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+## `importSkusUsingCsv()`
+
+```php
+importSkusUsingCsv($file): \OpenAPI\Client\Model\SkusImportCsvCreateResponseBody
+```
+
+Import SKUs using CSV
+
+Import SKUs into the repository using a CSV file. The CSV file has to include headers in the first line. All properties which cannot be mapped to standard SKU fields will be added to the metadata object. You can find an example template [here](https://s3.amazonaws.com/helpscout.net/docs/assets/5902f1c12c7d3a057f88a36d/attachments/627b98d08c9b585083488a4c/Import_SKUS_template.csv).  This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+## `updateProductsInBulk()`
+
+```php
+updateProductsInBulk($productsUpdateInBulkRequestBody): \OpenAPI\Client\Model\ProductsUpdateInBulkResponseBody
+```
+
+Update Products in Bulk
+
+Update products in one asynchronous operation. The request can include up to **10 MB** of data. The response returns a unique asynchronous action ID. Use this ID in the query paramater of the GET Async Action endpoint to check, e.g.: - The status of your request (in queue, in progress, done, or failed) - Resources that failed to be updated - The report file with details about the update If a product object is not found, it is **upserted**. This is shown in the report file in the GET Async Action endpoint. The upserted resources have value false in the found column and true in the updated column. This API request starts a process that affects Voucherify data in bulk. In the case of small jobs (like bulk update), the request is put into a queue and processed when every other bulk request placed in the queue prior to this request is finished.

+
+Create Publication
+
+This method selects vouchers that are suitable for publication, adds a publish entry and returns the publication. A voucher is suitable for publication when its active and hasnt been published yet.    🚧 Clearly define the source of the voucher  You must clearly define which source you want to publish the voucher code from. It can either be a code from a campaign or a specific voucher identified by a code.    🚧 Publish multiple vouchers  In case you want to publish multiple vouchers within a single publication, you need to specify the campaign name and number of vouchers you want to publish.    📘 Auto-update campaign  In case you want to ensure the number of publishable codes increases automatically with the number of customers, you should use an **auto-update** campaign.

+Create Publication
+
+This method selects vouchers that are suitable for publication, adds a publish entry and returns the publication. A voucher is suitable for publication when its active and hasnt been published yet.  ❗️ Limited access  Access to this endpoint is limited. This endpoint is designed for specific integrations and the API keys need to be configured to access this endpoint. Navigate to the **Dashboard** &rarr; **Project Settings** &rarr; **General** &rarr; **Integration Keys** to set up a pair of API keys and use them to send the request.    🚧 Clearly define the source of the voucher  You must clearly define which source you want to publish the voucher code from. It can either be a code from a campaign or a specific voucher identified by a code.    🚧 Publish multiple vouchers  This endpoint does not support the publishing of multiple vouchers from a single campaign. In case you want to publish multiple vouchers within a single publication, you need to use a dedicated endpoint.    📘 Auto-update campaign  In case you want to ensure the number of publishable codes increases automatically with the number of customers, you should use an **auto-update** campaign.   # Example Request      ❗️ Required    Query param voucher OR campaign MUST be filled out. If you provide both, campaign param will be skipped.

It means that if you have a referral program, a referrer is assigned only to one code if an integration sends publication requests more than once for the same customer. | [optional] |
+| **voucher** | **string**| Code of voucher being published. | [optional] |
+| **campaign** | [**CreatePublicationCampaign**](../Model/.md)| Create publication with campaign. | [optional] |
+| **sourceId** | **string**| The merchants publication ID if it is different from the Voucherify publication ID. Its an optional tracking identifier of a publication. It is really useful in case of an integration between multiple systems. It can be a publication ID from a CRM system, database or 3rd-party service. If source_id is provided only 1 voucher can be published per request. | [optional] |
+| **metadata** | [**object**](../Model/.md)| The metadata object stores all custom attributes assigned to the publication. A set of key/value pairs that you can attach to a publication object.

+List Publications
+
+Retrieve a list of publications. To return a **particular** publication, you can use the source_id query parameter and provide the source_id of the publication you are looking for specifically. # Pagination  🚧 Important!  If you want to scroll through a huge set of records, it is recommended to use the Exports API. This API will return an error page_over_limit if you reach a page above 1000. # Filter Query The filters query parameter allows for joining multiple parameters with logical operators. The syntax looks as follows:  ## Operators:  ## Examples

+
+Check Eligibility
+
+🚧 The Qualifications endpoint ignores the rules checking:    - Limit of total redeemed discount amount per campaign  - Limit of total redemptions count per campaign  - Redemptions per customer  - Redemptions per customer in a campaign  Generate a list of redeemables that are applicable in the context of the customer and order. The new qualifications method is an improved version of Campaign Qualifications, Voucher Qualifications, and Promotions Validation API requests. The new qualification method introduces the following improvements: - Qualification results are returned faster - No limit on the number of returned redeemables - Introduces new qualification scenarios, not available in the previous version  👍 Scenario Guide  Read the dedicated guide to learn about some use cases this endpoint can cover. # Paging  The Voucherify Qualifications API request will return to you all of the redeemables available for the customer in batches of up to 50 redeemables. To get the next batch of redeemables, you need to use the starting_after cursor. To process of paging the redeemables works in the following manner: - You send the first API request for Qualifications without the starting_after parameter. - The response will contain a parameter named has_more. If the parameters value is set to true, then more redeemables are available. - Get the value of the created_at parameter of the last returned redeemable. The value of this parameter will be used as a cursor to retrieve the next page of redeemables. - Send another API request for Qualification with the starting_after parameter set to the value taken from the created_at parameter from the last returned redeemable. - Voucherify will return the next page of redeemables. - If the has_more parameter is set to true, apply steps 3-5 to get the next page of redeemables.

+```php
+listRedemptions($limit, $page, $result, $campaign, $customer, $order, $createdAt, $filters): \OpenAPI\Client\Model\RedemptionsListResponseBody
+```
+
+List Redemptions
+
+Returns a list of redemptions previously created. The redemptions are returned in a sorted order, with the most recent redemptions appearing first. The response returns a list of redemptions of all vouchers.  # Filtering results The result can be narrowed according to specified (or default) filters, for example, you can sort redemptions by date: https://api.voucherify.io/v1/redemptions?limit 3&[created_at][before] 2017-09-08T13:52:18.227Z. A filter based on the object created_at field narrows down the results and lists redemptions done before or after a particular date time. You can use the following options: [created_at][after], [created_at][before]. A date value must be presented in ISO 8601 format (2016-11-16T14:14:31Z or 2016-11-16). An example: [created_at][before] 2017-09-08T13:52:18.227Z. # Failed Redemptions A redemption may fail for various reasons. You can figure out an exact reason from the failure_code: - resource_not_found - voucher with given code does not exist - voucher_not_active - voucher is not active yet (before start date) - voucher_expired - voucher has already expired (after expiration date) - voucher_disabled -  voucher has been disabled (active: false) - quantity_exceeded - vouchers redemptions limit has been exceeded - gift_amount_exceeded - gift amount has been exceeded - customer_rules_violated - customer did not match the segment - order_rules_violated - order did not match validation rules - invalid_order - order was specified incorrectly - invalid_amount - order amount was specified incorrectly - missing_amount - order amount was not specified - missing_order_items - order items were not specified - missing_customer - customer was not specified

+
+Redeem Stackable Discounts
+
+# How API returns calculated discounts and order amounts in the response In the table below, you can see the logic the API follows to calculate discounts and amounts:    📘 Rollbacks  You cant roll back a child redemption. When you call rollback on a stacked redemption, all child redemptions will be rolled back. You need to refer to a parent redemption ID in your rollback request.      📘 Also available on client-side  This method is also accessible through public keys which you can use in client-side​ apps: mobile and web browser apps. Go to the dedicated endpoint to learn more.  - Use X-Client-Application-Id as the application ID header.  - Use X-Client-Token as the appliction secret key header.  - Use client-side base URL.  - Use an origin header for your custom domain.

+
+Rollback Redemption
+
+Your business logic may include a case when you need to undo a redemption. You can revert a redemption by calling this API endpoint.  🚧  You can roll back a redemption up to 3 months back.   # Effect  The operation  - creates a rollback entry in vouchers redemption history (redemption.redemption_entries) and  - gives 1 redemption back to the pool (decreases redeemed_quantity by 1).  # Returned funds  In case of *gift card vouchers*, this method returns funds back according to the source redemption. In case of *loyalty card vouchers*, this method returns points back according to the source redemption.

+## `generateRandomCode()`
+
+```php
+generateRandomCode($body): \OpenAPI\Client\Model\VouchersCreateResponseBody
+```
+
+Generate Random Code
+
+Create a standalone voucher. You can choose to create a GIFT_VOUCHER, a DISCOUNT_VOUCHER, or a LOYALTY_CARD.  When you create a new voucher, you can specify a type to create it. Creating a new voucher will create a new stand alone voucher if no campaign name or campaign_id is provided. In case of the loyalty card, a campaign name is required. You can optionally use the code parameter to define a specific code or the code_config parameter to design rules for Voucherify API to create a random code. If neither of the two parameters are passed, then a random code is generated by the Voucherify API. This method will return an error when trying to create a voucher that already exists.

+## `importVouchers()`
+
+```php
+importVouchers($vouchersImportCreateItemRequestBody): \OpenAPI\Client\Model\VouchersImportCreateResponseBody
+```
+
+Import Vouchers
+
+Import standalone vouchers and gift cards into the repository.  📘 Important notes  - **Start and expiration dates** need to be provided in compliance with the ISO 8601 norms. For example, 2020-03-11T09:00:00.000Z.  - Custom code attributes (not supported by-default) need to be added as code **metadata**.  - You **cannot import the same codes** to a single Voucherify Project. Any parameters not provided in the payload will be left blank or null. For both **standalone discount vouchers and gift cards**, you can import the following fields:   - code - category - active - type - start_date - expiration_date - redemption.quantity - additional_info - metadata For **gift cards**, you can also import the following field: - gift.amount For **discount vouchers**, you can import the discount object. The object will slightly vary depending on the type of discount. Each discount type **requires** the type to be defined in the import.   Fields other than the ones listed above wont be imported. Even if provided, they will be silently skipped. This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+## `importVouchersUsingCsv()`
+
+```php
+importVouchersUsingCsv($file): \OpenAPI\Client\Model\VouchersImportCsvCreateResponseBody
+```
+
+Import Vouchers using CSV
+
+Import standalone vouchers into the repository using a CSV file. The CSV file has to include headers in the first line. All properties listed in the file headers that cannot be mapped to standard voucher fields will be added to the metadata object.   You can find an example CSV file [here](https://support.voucherify.io/article/45-import-codes-and-share-them-digitally#coupons). ___  📘 Standard voucher fields mapping  - Go to the import vouchers endpoint to see all standard CSV fields description (body params section).  - Supported CSV file headers: Code,Voucher Type,Value,Discount Type,Category,Start Date,Expiration Date,Redemption Limit,Redeemed Quantity, Redeemed Amount,Active,Additional Info,Custom Metadata Property Name - **Start and expiration dates** need to be provided in compliance with the ISO 8601 norms. For example, 2020-03-11T09:00:00.000Z.       - YYYY-MM-DD     - YYYY-MM-DDTHH     - YYYY-MM-DDTHH:mm     - YYYY-MM-DDTHH:mm:ss     - YYYY-MM-DDTHH:mm:ssZ     - YYYY-MM-DDTHH:mm:ssZ     - YYYY-MM-DDTHH:mm:ss.SSSZ  - Custom code attributes (not supported by-default) need to be added as code **metadata**.  - You **cannot import the same codes** to a single Voucherify Project.  📘 Categories  In the structure representing your data, you can define a category that the voucher belongs to. You can later use the category of a voucher to group and search by specific criteria in the Dashboard and using the List Vouchers endpoint. This API request starts a process that affects Voucherify data in bulk.  In case of small jobs (like bulk update) the request is put into a queue and processed once every other bulk request placed in the queue prior to this request is finished. However, when the job takes a longer time (like vouchers generation) then it is processed in small portions in a round-robin fashion. When there is a list of vouchers generation scheduled, then they will all have the IN_PROGRESS status shortly. This way, small jobs added just after scheduling big jobs of the same type will be processed in a short time window.  The result will return the async ID. You can verify the status of your request via this API request.

+
+```php
+listVouchers($limit, $page, $category, $campaignId, $customer, $campaign, $createdAt, $updatedAt, $order, $code, $ids): \OpenAPI\Client\Model\VouchersListResponseBody
+```
+
+List Vouchers
+
+Returns a list of vouchers. By default, the vouchers are returned sorted by creation date, with the most recent vouchers appearing first. A maximum of 100 vouchers are returned in the response. When you get a list of vouchers, you can optionally specify query parameters to customize the number of vouchers returned per call using limit, which page of vouchers to return using page, sort the vouchers using the order query parameter and more. This method will return an error when trying to return a limit of more than 100 vouchers.
