Delivery and Retry Policy

We will only notify your postbackWebhookUrl when the events listed Event Types occur. If your webhook endpoint is not responding, we will retry the delivery several times before eventually dropping the notification.

Retry Schedule

Each message is 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 (again, in addition to the previous attempt)

Best Practices

Please ensure that your infrastructure to receive webhooks is robust and can handle all possible webhook events and error scenarios. Be sure to implement proper error handling logic, and always validate the data you receive from us against the provided HMAC signatures.
