It is expected that you respond to an event notification with a status response code of 200 (OK). This code will be used by us to acknowledge that you received the notification. Any status response code outside of the 2xx series will be considered a failed response and we will continue to retry regularly for up to 7 days, at increasing time intervals as follows:
After that, retries happen every 8 hours for the following 7 days. If we do not receive a response within the 2XX series, all notifications to this endpoint will be queued. Subsequently, we will attempt to retry sending the notification to your endpoint until it is accepted. Once accepted, you will receive all queued notifications as well.
