WhatsApp API Webhook: Meaning and How It Works

A webhook lets your server receive events from a communication platform without repeatedly checking for updates.

When an event occurs, the provider sends an HTTP request to a registered endpoint. The payload may include a message ID, status, timestamp or other event information needed by your application.

Why are webhooks important?

A webhook endpoint should respond quickly. Move heavy work to a queue, validate incoming requests and never trust external payloads without verification.

Reliable webhook implementation

Store events idempotently using a relevant identifier so repeated webhook delivery does not create duplicate data or incorrect status changes.
