Setup & Handling
This section explains how to correctly configure and process webhook notifications in your system. Here you will learn how to:
Create and expose a webhook endpoint
Receive events sent by Comm.Pix
Validate that events are authentic
Process payloads safely and reliably
Handle retries and duplicate deliveries
What This Means in Practice
To use webhooks successfully, your system must:
Expose an HTTP endpoint that can receive POST requests.
Validate each incoming request (signature, headers, or source).
Process the event based on its type and content.
Return a successful response to confirm delivery.
Be prepared to receive the same event more than once.
This section will guide you through each of these steps with examples and best practices.
Reliability and Security
Webhooks are critical for real-time payment updates. For this reason, you should:
Always validate the authenticity of each event.
Design your handler to be idempotent.
Log and monitor webhook deliveries.
Handle temporary failures gracefully.
Following these guidelines ensures that your integration is secure, stable, and production-ready
