How Aadhini eMessenger works with WhatsApp Cloud API

Set up your WhatsApp Cloud API app in the Meta Developer Console and obtain your access token and phone number ID.
Configure the webhook callback URL to point to your Aadhini eMessenger endpoint (for example, https://yourdomain.com/webhook/index.php).
Use Aadhini eMessenger to receive, log, and respond to inbound messages, and to trigger outbound notifications from your business systems.

Developer quick start

Use the webhook example above together with your own sending logic (via the WhatsApp Cloud API send message endpoint) to build custom workflows for alerts, reminders, and interactive customer support.

You can extend the integration with message templates, media messages, and interactive buttons supported by the WhatsApp Business Platform Cloud API.
