Response to callback

Your service's server must respond to each callback request with the HTTP status code 200 OK. If there is no response within 3 seconds, a timeout will occur. Kakao checks only the HTTP status code to determine whether the request is successful.

Disable callback

If your service's server does not respond to the callback requests longer than a month or errors frequently occur, each callback setting will be turned to [Disabled] until being enabled again.
