hugentobler

* Simple, free webhook to start using WhatsApp Platform. * Handles GET request for verification, and POST request for notifications. * Meta example: https://glitch.com/edit/#!/whatsapp-cloud-api-echo-bot * * Setup: * 1. Make sure your val name, and thus the val generated HTTP endpoint does not have underscores. * Underscores present in the endpoint may error out the verification step. * 2. Set your env variable `WHATSAPP_WEBHOOK_VERIFY_TOKEN` * Set env variables in val: https://docs.val.town/reference/environment-variables/ * hub.verify_token value: https://developers.facebook.com/docs/graph-api/webhooks/getting-started * * Note: * - As of Mar 2024, Retool webhooks don't support GET requests. So we use val.
