LinkedIn

Get your LinkedIn credentials

To use LinkedIn sign in, you need a client ID and client secret. You can get them from the LinkedIn Developer Portal.

Make sure to set the redirect URL to http://localhost:3000/api/auth/callback/linkedin 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.

Configure the provider

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

import { betterAuth } from "better-auth"
 
export const auth = betterAuth({
    socialProviders: { 
        linkedin: { 
            clientId: process.env.LINKEDIN_CLIENT_ID as string, 
            clientSecret: process.env.LINKEDIN_CLIENT_SECRET as string, 
        }, 
    }, 
})

Signin with LinkedIn

To signin with LinkedIn, 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 linkedin.

import { createAuthClient } from "better-auth/client"
const client = createAuthClient()
 
const signin = async () => {
    const data = await client.signIn.social({
        provider: "linkedin"
    })
}
