Retries and failure recovery

Retries

Ansa attempts to deliver each webhook message based on a retry schedule with exponential backoff.

The schedule

Each message is attempted based on the following schedule, where each period is started following the failure of the preceding attempt:

• Immediately
• 5 seconds
• 5 minutes
• 30 minutes
• 2 hours
• 5 hours
• 10 hours
• 10 hours (in addition to the previous)

If an endpoint is removed or disabled delivery attempts to the endpoint will be disabled as well.

For example, an attempt that fails three times before eventually succeeding will be delivered roughly 35 minutes and 5 seconds following the first attempt.

Manual retries

You can also use the application portal to manually retry each message at any time, or automatically retry ("Recover") all failed messages starting from a given date.

Failure Recovery

Re-enable a disabled endpoint

If all attempts to a specific endpoint fail for a period of 5 days, the endpoint will be disabled. To re-enable a disabled endpoint, go to the webhook dashboard, find the endpoint from the list and select "Enable Endpoint".

Retrying requests

At times you may need to manually retry a single request, all recently failed requests, or trigger requests for all recent events that were not attempted.

This can be particularly useful if an API endpoint was temporarily misconfigured or if your service experienced downtime.

To retry a single request, find the message in the Webhooks Management Portal, click the options menu next to the attempt you’d like to retry, and click the “Replay” button to resend the webhook request to your API endpoint.

To retry all recently failed requests, select the relevant API endpoint from the Webhooks Management Portal, click the options menu at the top of the page, and click the “Recover failed messages” button.

To trigger requests for all recent events that were not attempted, select the relevant API endpoint from the Webhooks Management Portal, click the options menu at the top of the page, and click the “Replay missing messages” button.
