Polling guidelines

To find out if a user has approved a request, you will need to poll for the response through the API:

Some APIs provide webhooks and callbacks, but you shouldn't rely on these alone.

Our general guidelines for polling are:

  1. Start after 5 seconds
  2. Check every 2 seconds

However, different merchants have different use cases, and values should be adapted to the specific case.

Some APIs limit the rate of polling to prevent incorrect use. If you get a HTTP 429 Too Many Requests error, please try to reduce your polling speed.

For more details about rate limiting, see the relevant API details:
