# Retries and failures

> How SendKit handles failed webhook deliveries

## Retry behavior

When a webhook delivery fails, SendKit automatically retries the request:

SendKit makes up to **3 total attempts** (1 initial + 2 retries) with a 60-second delay between each:

| Attempt           | Delay                              |
| ----------------- | ---------------------------------- |
| Initial request   | Immediate                          |
| 1st retry         | 60 seconds after initial failure   |
| 2nd retry (final) | 60 seconds after 1st retry failure |

A delivery is considered failed when:

* Your endpoint returns a non-2xx status code
* The request times out (10 second limit)
* The connection cannot be established

## Automatic pausing

If a webhook accumulates **5 consecutive failures**, SendKit automatically pauses it to prevent unnecessary load on your server. A failure is counted once all 3 attempts for a single delivery are exhausted — individual retry attempts do not count separately. When this happens:

* The webhook status changes to **Paused**
* The team owner receives an email notification
* No further deliveries are attempted until you re-enable the webhook

To resume deliveries, go to the webhook settings in your dashboard and change the status back to **Enabled**. This resets the failure counter.

## Best practices

<Tip>
  Always return a `200` status code as quickly as possible. Process webhook data asynchronously in a background job.
</Tip>

* **Respond within 10 seconds** — Requests that take longer will time out and count as a failure.
* **Use HTTPS** — Webhook endpoints must use HTTPS.
* **Handle duplicates** — Webhooks may be retried, so make your processing idempotent.
* **Replay events** — Use the replay feature in the dashboard to re-send any past webhook delivery.

## Monitoring

Every webhook delivery is logged with:

* The full request payload
* Response status code and body
* Delivery timestamp or failure timestamp
* Number of attempts

You can view these logs in real time from the webhook detail page in your dashboard.
