Failure Notification

In this section you become familiar with the following parts of the in-game payment integration procedure:

How to interpret the POST data parameters included in the callback notification e-mail triggered by the payment callback function.

Info

When a payment reaches a specific status, the payment callback returns POST data to the game or the application.Use this information to validate the payment operation.Reply to this callback by sending a standard 200 OK HTTP response:

  • Status line: 200, and
  • Message body: [OK] (include the square brackets as well).

Send this reply to every payment notification you receive through the callback, regardless the reported payment status.

When you reply to the callback URL with [OK], you stop receiving automated callback notifications for payment transactions.

If you do not send this reply, callback POST data for payment transactions remain in the payment queue for 7 days/one week; during this period, callback notifications are sent on an hourly basis.

Callback failure notifications are automated e-mails triggered by the payment callback. They are sent to the following recipients:

The POST data format is always plain text, regardless the Content-Type header field value.

E-mail subject

Callback notification e-mail subjects follow the pattern described in the table below.

In an actual e-mail subject, the <game name> placeholder is replaced with the game name the callback failure notification refers to.

Environment E-mail subject
Live [Payment Service LIVE] Callback failure: <game name>

URL

The URL section contains the payment callback URL you as a game developer set and configure in the payment administration tool.

Use it to validate payment data on your end.

HEADERS

The HEADERS section contains the HTTP headers you as a game developer define and send along with the response.

Typical HTTP headers that can be included in a callback notification are:

The Status header and the status code associated to it can provide information about possible issues, for example when a payment fails (status code:404) or when the partner’s server behaves unexpectedly (status code: 500).

BODY

The BODY section contains the callback message body. You as a game developer define it. It can be anything you want to include.

If you want to stop receiving automated callback notifications for a given payment transaction, you need to reply with [OK] (square brackets included) in the BODY section. In this way, the POST data associated to that payment transaction are removed from the payment queue, and notification e-mail sending is stopped.

The BODY section contains the POST data parameters.

The table below lists the supplied POST parameters and their corresponding values.
