Retry Schedule

A retry schedule for webhooks is a predefined strategy that governs how and when failed webhook delivery attempts are retried. When a webhook delivery fails due to factors such as network issues, server errors, or timeouts, the retry schedule determines the timing and frequency of subsequent retry attempts.

Trackunit's Retry Schedule

Trackunit attempts to deliver each webhook message based on a retry schedule with exponential backoff.
Each message is therefore 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)

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

Failed delivery handling & manual retries

After the conclusion of the above attempts the message will be marked as 'Failed' for this endpoint. You can then use the interface under Administration → Webhooks in the Trackunit Manager to manually replay each message at any time, or automatically retry / recover all failed messages starting from a given date.
