    This is an old version of the API. Switch to the new API version.

    Interface method PayMaster's API methods are available via HTTP requests to the specific URLs.

    All the requests should be transmitted over TLS. The base endpoint address is https://paymaster.ru

    Authenticating requests

    All requests are carried out on behalf of users that were created with the Automatic access login method. Users should have assigned the Cashier (acquiring a payment status and list of payments) or Accountant (Cashier + payment refund + list of refunds + confirmation and cancellation of holds) role. All requests must contain three fields: login, nonce, and hash, which are used to authenticate requests:

    If the request signature (hash) is incorrect, PayMaster returns the error code -7 (see Error codes).

    Attention! When the GET string is generated, all parameters (especially the hash) should be encoded with URL!

    Response format

    Response example:

    {
      "ErrorCode": 0,
      "Payment": {
        "PaymentID": 1,
        "SiteInvoiceID": "12345",
        "SiteID": 1,
        "CurrencyCode": "RUB",
        "Amount": 100,
        "PaymentCurrencyCode": "RUB",
        "PaymentAmount": 100,
        "State": "COMPLETE",
        "IsTestPayment": false,
        "LastUpdateTime": "2013-05-22T18:08:52"
      }
    }
    

    In response to the request, PayMaster always returns HTTP code 200. If another code is returned, there has been a server error while parsing the request. PayMaster generates responses in the JSON format.

    All responses contain a numeric ErrorCode field equal to the request error code (see Error codes). The parameters of request responses can be expanded by making the appropriate changes to the documentation. Write the response processing code in such as way as to take into account that you may receive additional fields.
