How to interpret the POST data parameters included in the callback notification e-mail triggered by the payment callback function.
Send this reply to every payment notification you receive through the callback, regardless the reported payment status.
When you reply to the callback URL withÂ [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 theÂ payment callback. They are sent to the following recipients:
The POST data format is alwaysÂ plain text, regardless theÂ Content-TypeÂ header fieldÂ value.
Callback notification e-mail subjects follow the pattern described in the table below.
In an actual e-mail subject, theÂ <game name>Â placeholder is replaced with the game name the callback failure notification refers to.
|Live||[Payment Service LIVE] Callback failure: <game name>|
TheÂ URLÂ section contains theÂ payment callback URLÂ you as a game developer set and configure in theÂ payment administration tool.
Use it to validate payment data on your end.
TheÂ HEADERSÂ section contains theÂ HTTP headersÂ you as a game developer define and send along with the response.
Typical HTTP headers that can be included in a callback notification are:
TheÂ StatusÂ header and theÂ status codeÂ 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:Â 500).
TheÂ BODYÂ 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 withÂ [OK]Â (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.
TheÂ BODYÂ section contains the POST data parameters.
The table below lists the supplied POST parameters and their corresponding values.
