PostFinance Checkout TypeScript Library

The PostFinance Checkout TypeScript library wraps around the PostFinance Checkout API. This library facilitates your interaction with various services such as transactions, accounts, and subscriptions.

Documentation

PostFinance Checkout Web Service API

Requirements

• npm 6+

Installation

NPM install (recommended)

npm install postfinancecheckout

Usage

The library needs to be configured with your account's space id, user id, and secret key which are available in your PostFinance Checkout account dashboard. Set space_id, user_id, and api_secret to their values. You can also add custom default headers to the configuration.

Configuring a Service

'use strict';
import { PostFinanceCheckout } from 'postfinancecheckout';

let spaceId: number = 405;
let userId: number = 512;
let apiSecret: string = 'FKrO76r5VwJtBrqZawBspljbBNOxp5veKQQkOnZxucQ=';

let config = {
    space_id: spaceId,
    user_id: userId,
    api_secret: apiSecret
    default_headers: {
        'x-meta-header-name-1': 'header-value-1',
        'x-meta-header-name-2': 'header-value-2'
    }
}

// Transaction Service
let transactionService: PostFinanceCheckout.api.TransactionService = new PostFinanceCheckout.api.TransactionService(config);

To get started with sending transactions, please review the example below:

'use strict';
import { PostFinanceCheckout } from 'postfinancecheckout';

let spaceId: number = 405;
let userId: number = 512;
let apiSecret: string = 'FKrO76r5VwJtBrqZawBspljbBNOxp5veKQQkOnZxucQ=';

let config = {
    space_id: spaceId,
    user_id: userId,
    api_secret: apiSecret
}

// Transaction Service
let transactionService: PostFinanceCheckout.api.TransactionService = new PostFinanceCheckout.api.TransactionService(config);

// TransactionPaymentPage Service
let transactionPaymentPageService: PostFinanceCheckout.api.TransactionPaymentPageService = new PostFinanceCheckout.api.TransactionPaymentPageService(config);

// LineItem of type PRODUCT
let lineItem: PostFinanceCheckout.model.LineItemCreate = new PostFinanceCheckout.model.LineItemCreate();
lineItem.name='Red T-Shirt';
lineItem.uniqueId='5412';
lineItem.sku='red-t-shirt-123';
lineItem.quantity=1;
lineItem.amountIncludingTax=3.50;
lineItem.type=PostFinanceCheckout.model.LineItemType.PRODUCT;

// Transaction
let transaction: PostFinanceCheckout.model.TransactionCreate = new PostFinanceCheckout.model.TransactionCreate();
transaction.lineItems=[lineItem];
transaction.autoConfirmationEnabled=true;
transaction.currency='EUR';

transactionService.create(spaceId, transaction).then((response) => {
    let transactionCreate: PostFinanceCheckout.model.Transaction = response.body;
    transactionPaymentPageService.paymentPageUrl(spaceId, <number> transactionCreate.id).then(function (response) {
        let pageUrl: string = response.body;
        // window.location.href = pageUrl;
    });
});

Configure connection timeout

Connection timeout determines how long the request can take, before cutting off the connection. Same value applies both to inner 'Read timeout' and 'Connection timeout' of a NPM request module.

Default connection timeout is 25s.

Connection timeout can be set 2 ways:

1. Via configuration property 'timeout' providing value in seconds.

let config = {
    ... other properties ...
    timeout: 15
}
let transactionService: PostFinanceCheckout.api.TransactionService = new PostFinanceCheckout.api.TransactionService(config);

2. Via service property 'timeout' providing value in seconds

let config = {
    ... properties ...
}
let transactionService: PostFinanceCheckout.api.TransactionService = new PostFinanceCheckout.api.TransactionService(config);
transactionService.timeout = 15;
