Facebook Messenger (Messenger Platform) Social, ads and analytics # Connect Facebook Messenger (Messenger Platform) to Hypamoon Yes, with one catch. Facebook Messenger (Messenger Platform) has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today. Open ## The check Three questions about the API of Facebook Messenger (Messenger Platform), answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://developers.facebook.com/docs/messenger-platform/overview) **A key you create yourself**\ **Yes.** Create your own Meta app and get a Page access token from a Page admin. App Review is not needed when you only message for your own Page. [developers.facebook.com](https://developers.facebook.com/docs/messenger-platform/overview) **Versions or a changelog**\ **Yes.** Runs on the Graph API with numbered versions (v25.0, v26.0 and later), each available for about two years. [developers.facebook.com](https://developers.facebook.com/docs/graph-api/changelog) **How it signs in**\ A Page access token from Facebook Login for Business with pages\_messaging and related permissions; the user must have messaging rights on the Page. **Webhooks**\ **Yes.** It can tell your app when something changes. [developers.facebook.com](https://developers.facebook.com/docs/messenger-platform/overview) **Hosting**\ Cloud **Condition**\ Serving Pages of other businesses needs Advanced Access through App Review and Business Verification. ## What you can build Answer Messenger messages on your own Facebook Page from one inbox, and let AI draft replies for you to approve. 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](https://hypamoon.com/docs/adapters) ### Good to know - Facebook Messenger (Messenger Platform) signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Facebook Messenger (Messenger Platform) takes more work: ask your chat to check this first. - You may reply freely within 24 hours of the customer's last message; after a click-to-Messenger ad the window can be up to 7 days. ## Try it in your chat Fill in what to read and write, and send it.
