Slack OAuth pre-configured provider setup example
To use Slack as an OAuth provider, import slack from 'better-auth/plugins' and configure it with clientId and clientSecret. Example: ```ts import { betterAuth } from "better-auth" import { genericOAuth, slack } from "better-auth/plugins" export const auth = betterAuth({ plugins: [ genericOAuth({ config: [ slack({ clientId: process.env.SLACK_CLIENT_ID, clientSecret: process.env.SLACK_CLIENT_SECRET, }), ], }), ], }) ```
Slack requires HTTPS in production
Slack requires HTTPS for redirect URLs in production environments. For local development, tools like ngrok can be used to create a secure tunnel.
Slack configuration with clientId and clientSecret
To configure Slack provider in auth configuration, pass clientId and clientSecret to socialProviders.slack in the betterAuth configuration object.
Slack app creation steps
To create a Slack app for authentication: go to Your Apps on Slack API (https://api.slack.com/apps), click 'Create New App', choose 'From scratch', give your app a name and select a development workspace.
Slack sign-in configuration example
Example Slack provider configuration: ```ts import { betterAuth } from "better-auth" export const auth = betterAuth({ socialProviders: { slack: { clientId: process.env.SLACK_CLIENT_ID as string, clientSecret: process.env.SLACK_CLIENT_SECRET as string, }, }, }) ```
Sign in with Slack using client
To sign in with Slack, use the signIn.social function with provider set to 'slack': ```ts import { createAuthClient } from "better-auth/client"; const authClient = createAuthClient(); const signIn = async () => { const data = await authClient.signIn.social({ provider: "slack" }); }; ```
Slack default OpenID Connect scopes
By default, Slack provider uses OpenID Connect scopes: openid, profile, and email.
Slack additional scopes during sign-in
Additional Slack API scopes can be requested during sign-in by passing a scopes array to signIn.social: ```ts const signInWithSlack = async () => { await authClient.signIn.social({ provider: "slack", scopes: ["channels:read", "chat:write"], }); }; ```
Slack workspace-specific sign-in configuration
To restrict sign-in to a specific Slack workspace, pass the team parameter with the Slack workspace ID: ```ts socialProviders: { slack: { clientId: process.env.SLACK_CLIENT_ID as string, clientSecret: process.env.SLACK_CLIENT_SECRET as string, team: "T1234567890", }, } ```
Slack redirect URL for local development
For local development with Slack provider, the redirect URL should be http://localhost:3000/api/auth/callback/slack
Access Slack user information after authentication
After successful authentication, the user's Slack ID can be accessed through the session. The access token is stored securely on the server and can be used to make requests to the Slack API.
Slack redirect URL for production
For production with Slack provider, the redirect URL should be https://yourdomain.com/api/auth/callback/slack
