Communication

Slack V2 OAuth Integration

Connect Slack V2 to your application without building and maintaining the OAuth flow.

Slack is a messaging platform for teams. Each user connects their own Slack V2 account through your OAuth app. Pathfix manages the authorization flow, stores and refreshes their tokens, and authenticates the requests your application makes to the Slack V2 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 Slack V2 OAuth app, so users approve access on Slack’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 Slack V2 issues refresh tokens, Pathfix refreshes them as they expire, so connections keep working after the first authorization.
04
Authenticated API passthrough
Your application sends Slack V2 API requests through Pathfix, which adds the connected user’s credentials before passing them on to Slack V2.

You own the Slack V2 OAuth application and its credentials, and your code implements the API logic.

How to get started

1
Register your app with Slack
Create an app in Slack’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 Slack V2 from the providers and enter the Client ID and Client Secret.
3
Choose your scopes
Add only the scopes your integration needs. Slack’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 Slack V2 and approves the scopes you requested.
6
Call the Slack V2 API
Send requests through the Pathfix passthrough API using the provider reference slackv2.
