You can process payments across the globe and across multiple channels with scalability and security. An extensive list of payment cards and a wide choice of gateways and acquiring banks are supported through one connection.

eCommerce Payments 101

Payment APIs reflect the following RESTful API concepts:
  • Resources
    —these provide access to payment functions such as authorizations and captures. A resource’s unique ID provides access to an individual payment object such as an authorization.
  • HTTP verbs and status codes
     retrieves resource details. 
     submits a request, such as payment authorization, that changes the state of the resource. HTTP status code 200 indicates a successful 
     call. Other HTTP status codes, such as 400 and 502, indicate unsuccessful calls. HTTP status code 201 indicates a successful 
     call. Other HTTP status codes, such as 400 and 502, indicate unsuccessful calls.
  • Hypermedia links for follow-on actions
    —JSON Hypertext Application Language (HAL) informs the follow-on actions performed on a resource. For example, when a payment capture follows a successful payment authorization, and the HTTP Accept header is either not found or has the value 
    , the payment API returns a response with HAL links. When the HTTP Accept header has the value 
    , the API returns plain JSON objects without HAL links.
