Connect WhatsApp Business Platform to Hypamoon
Yes. WhatsApp Business Platform has a public, versioned API and you create the key yourself, so your chat can write the adapter.
OpenThe check
Three questions about the API of WhatsApp Business Platform, answered from its own docs.
- Public API docs
- Yes. Read the docs
- A key you create yourself
- Yes. A business that uses the Cloud API for its own WhatsApp account needs no App Review; the app gets Standard Access automatically. App Review is only needed to serve other businesses. developers.facebook.com
- Versions or a changelog
- Yes. Graph API versions such as v25.0, each available for about two years, with a changelog. developers.facebook.com
- How it signs in
- A system user access token from Meta Business Settings, sent as a Bearer token; the short test token from the dashboard expires quickly. Embedded signup with OAuth for providers serving other businesses.
- Webhooks
- Yes. It can tell your app when something changes. developers.facebook.com
- Hosting
- Cloud
- Condition
- You need a Meta developer account, a Meta app with the WhatsApp use case and a business portfolio. Serving other businesses needs App Review for Advanced Access.
What you can build
Send appointment reminders and order updates on WhatsApp, and route incoming WhatsApp messages to the right person.
Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work
Good to know
- Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
- Inbound messages and delivery statuses arrive through webhooks, so you need a public endpoint.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
