# Retry Behavior

> Understand Paywint webhook delivery and retry logic.

Paywint guarantees **at-least-once** delivery for all webhook events.\
If your endpoint does not return a `2xx` HTTP response, the system automatically retries.

***

## Retry Policy

| Attempt       | Delay after previous try | Condition             |
| ------------- | ------------------------ | --------------------- |
| 1st (initial) | —                        | Original delivery     |
| 2nd           | \~1 minute               | No `2xx` response     |
| 3rd           | \~5 minutes              | Second attempt failed |

After the final failed attempt, an email is sent to the registered **admin address** with details of the undelivered event.

***

## Best Practices

* Return `200 OK` **within 5 seconds**; offload heavy work to background jobs.
* Store and de-duplicate by `event id` to ensure idempotency.
* Implement exponential backoff if you **replay** events from your side.
* Monitor endpoint health (latency and error rates).
