Twitter (X)

Get your Twitter Credentials

Get your Twitter credentials from the Twitter Developer Portal.

Make sure to set the redirect URL to http://localhost:3000/api/auth/callback/twitter for local development. For production, you should set it to the URL of your application. If you change the base path of the auth routes, you should update the redirect URL accordingly.

Twitter API v2 does not provide email addresses. As a workaround, the user's email field uses the username value instead.

Configure the provider

To configure the provider, you need to import the provider and pass it to the socialProviders option of the auth instance.

auth.ts
import { betterAuth } from "better-auth" 
 
export const auth = betterAuth({
    socialProviders: {
        twitter: { 
            clientId: process.env.TWITTER_CLIENT_ID, 
            clientSecret: process.env.TWITTER_CLIENT_SECRET, 
        }, 
    },
})

Sign In with Twitter

To sign in with Twitter, you can use the signIn.social function provided by the client. The signIn function takes an object with the following properties:

  • provider: The provider to use. It should be set to twitter.
auth-client.ts
import { createAuthClient } from "better-auth/client"
const authClient =  createAuthClient()
 
const signIn = async () => {
    const data = await authClient.signIn.social({
        provider: "twitter"
    })
}
