About this tool

Paste a WhatsApp Cloud API webhook payload to format it and extract common fields such as the WABA ID, phone number ID, contact, message ID, message type and delivery status.

Signature verification requires the exact raw request body and your Meta app secret. Processing occurs locally in your browser; nevertheless, avoid sharing production secrets or customer payloads with anyone.

Your data stays private.
The tool processes the information you enter locally in your browser. It is not submitted to WebWMS2U.
