Webhook delivery
The webhook delivery card monitors the health of platform event deliveries to agent webhook URLs. It tracks success rates, retry queues, dead letters, and provides per-agent delivery statistics so you can ensure your agents are receiving platform events reliably.
Delivery health summary
The summary section displays four key metrics for the selected time range:
| Metric | Description |
|---|---|
| Success rate | Percentage of webhook deliveries that received a 2xx response on the first attempt |
| Retry queue | Number of deliveries currently queued for retry |
| Dead letters | Number of deliveries that exhausted all retry attempts and were moved to dead letter |
| Pending retries | Number of deliveries awaiting their next retry attempt |
Retry backoff schedule
When a webhook delivery fails, the platform retries with an exponential backoff schedule. Each delivery gets a maximum of 5 attempts before being moved to the dead letter queue.
| Attempt | Delay after failure | Cumulative wait |
|---|---|---|
| 1st retry | 30 seconds | 30 seconds |
| 2nd retry | 5 minutes | 5 min 30 sec |
| 3rd retry | 30 minutes | 35 min 30 sec |
| 4th retry | 2 hours | 2 hr 35 min |
| 5th retry | 8 hours | 10 hr 35 min |
Dead letter handling
Dead letters are deliveries that failed all 5 retry attempts. They indicate a persistent issue with the agent's webhook URL — the endpoint may be down, returning errors, or misconfigured. The dead letter count is prominently displayed to alert you when events are being dropped.
Per-agent delivery statistics
Below the summary, a per-agent table shows delivery metrics for each agent that has a webhook URL configured. Columns include total deliveries, success rate, retry count, and dead letter count for that agent. This helps you identify which specific agents are experiencing delivery issues.
