Payment session regulation parameters

A mechanism exists for regulating the time allotted for payment from the Internet Resource's side. To use it, a parameter must be passed in the authorization request indicating the starting point for counting the allotted payment interval (default is 20 minutes).

The authorization request must include either:

• The wsb_startsessdatetime parameter with a value of type DateTime (e.g., 2020-10-22T16:20:01+03:00)
• Or the wsb_startsesstime parameter, which contains a value in UnixTimestamp format (e.g., 1603383601)

If both parameters are provided, wsb_startsessdatetime takes priority.

Example: A transaction starts on 22.10.2020 at 16:33:01. The Internet Resource wants the payment session to be valid for 7 minutes. The POST request must therefore contain the start time 22.10.2020 16:20:01.

Code example

<input type="hidden" name="wsb_startsesstime" value="1603383601">
<input type="hidden" name="wsb_startsessdatetime" value="2020-10-22T16:20:01+03:00">
