Communication

Messenger OAuth Integration

Connect Messenger to your application without building and maintaining the OAuth flow.

Messenger is Meta's messaging platform. Each user connects their own Messenger account through your OAuth app. Pathfix manages the authorization flow, stores and refreshes their tokens, and authenticates the requests your application makes to the Messenger API. What your integration does with that access is up to your code.

How Pathfix helps

01
OAuth authorization
Pathfix runs the authorization flow with your Messenger OAuth app, so users approve access on Messenger’s own consent screen.
02
Token management
Each user’s access and refresh tokens are stored by Pathfix rather than in your application.
03
Token refresh
Where Messenger issues refresh tokens, Pathfix refreshes them as they expire, so connections keep working after the first authorization.
04
Authenticated API passthrough
Your application sends Messenger API requests through Pathfix, which adds the connected user’s credentials before passing them on to Messenger.

You own the Messenger OAuth application and its credentials, and your code implements the API logic.

How to get started

1
Register your app with Messenger
Create an app in Messenger’s developer settings to get a Client ID and Client Secret. When asked for a redirect URI, enter https://labs.pathfix.com/integrate/command.
2
Add the credentials in Pathfix
In your Pathfix account, add an application, select Messenger from the providers and enter the Client ID and Client Secret.
3
Choose your scopes
Add only the scopes your integration needs. Messenger’s developer documentation lists what each scope allows.
4
Test the connection
Use Test Connection to connect an account in the API Playground and run a sample call.
5
Let your users authorize
Add the connect step to your app. Each user signs in to Messenger and approves the scopes you requested.
6
Call the Messenger API
Send requests through the Pathfix passthrough API using the provider reference messenger.
