One webhook for WhatsApp, Instagram and Messenger — the payload shape that lets you write a single parser

Integrating WhatsApp, Instagram Direct, and Messenger typically requires managing three separate APIs, credentials, and webhook formats. This creates a maintenance burden with multiple parsers for the same functional goal of responding to messages. The proposed solution involves collapsing these into a single integration using one endpoint and one API key. By normalizing the webhook envelope rather than the content, developers can use a single parser to identify the message source via a specific channel field.
