API integration on the website: The website requires writing code that will interact with the payment system API. Typically, it contains HTTP requests to the API using the required parameters and transferring payment data. Depending on the payment system and their provided API, requests can be sent using the POST or GET method.

The requests usually include information about the payment amount, description, currency, and the customer's payment details.

It then returns a response to the site containing information about the payment status (successful, declined, pending, etc.) and other transaction details.
