Available methods & options

Creating instance with your API Key and options (optional)

$options = array(
    'timeout' => 30,
    'verifySSL' => false
);
$omnisend = new Omnisend('API-KEY', $options);

Available options:

Name	Type	Description
timeout	int	Timeout. If not passed - will be calculated depending on PHP max_execution_time
verifySSL	bool	Default - true. Enable (true) or disable (false) SSL verification.

Available methods

endpoint - endpoint url (ex. 'contacts', 'products/prod123'). See documentation for available endpoints.

queryParams - array of query parameters

fields - array of fields

• getSnippet() - returns html snippet code
• get(endpoint, queryParams) - make GET request.
• push(endpoint, fields, queryParams) - makes POST request. If error occurs (resource exists in Omnisend) - makes PUT request. This method can be used if you don't know if item exists in Omnisend. queryParams - optional.
• post(endpoint, fields, queryParams) - make POST request. Used to create new item in Omnisend. Will return an error if an item already exists in Omnisend. queryParams - optional.
• put(endpoint, fields, queryParams) - make PUT request. Used to replace item in Omnisend. Will return an error if an item doesn't exists in Omnisend. queryParams - optional.
• patch(endpoint, fields, queryParams) - make PATCH request. Used to update item in Omnisend. Will return an error if an item doesn't exists in Omnisend. queryParams - optional.
• delete(endpoint, queryParams) - make DELETE request. Used to delete item in Omnisend. Will return an error if an item doesn't exists in Omnisend. queryParams - optional.

Responses

Each method will return false in case of an error, array (see documentation for responses) or true (for empty body (204) responses) in case of a success.

So you can easily check if a request was successful:

$cart = $omnisend->delete('carts/cart-123');
if ($cart) {
    //request was successful
} else {
    //there was an error
}

In case of a failed request, you can get an error description with lastError():

 var_dump($omnisend->lastError());

Output will be an array with:

• error - error description
• statusCode - HTTP response status code
• fields - optional - array of missing required, incorrect or incorrectly formatted fields (passed with a request)

Example:

array {
  ["error"]=> "2 error(s) found. Check 'fields' array for details."
  ["statusCode"]=> 400
  ["fields"]=>
  array {
    [0]=>
    array {
      [0]=> "cartSum: field required but not found in Json"
    }
    [1]=>
    array {
      [0]=> "currency: field required but not found in Json"
    }
  }
}

Examples

1. Create an instance with your API key and options (optional)

$omnisend = new Omnisend('your-api-key');

2. Make a request, for example, create a new contact in Omnisend:

$contacts = $omnisend->post(
  'contacts',
   array(
       "email" => "[email protected]", 
       "firstName" => "Vanessa", 
       "lastName" => "Kensington", 
       "status" => "subscribed", 
       "statusDate" => "2018-12-11T10:29:43+00:00"
    )
);

3. Check if a request was successful:

if ($contacts) {
    //request was successful

    //print response
    print_r($contacts); 
    //get contactID from response
    $contactID = $contacts['contactID'];
} else {
    //there was an error
    print_r($omnisend->lastError());
}
