 **Duplicate webhook events**
 
-Duplicate webhooks can happen. For this reason, apps should use idempotent operations to avoid significant unintended side effects. Idempotent operations allow multiple calls without changing the result.

When you receive a webhook, you can compare the hash of the received event to the list. If the hash has already been handled you can ignore the event.
