Figma

Get your Credentials

1. Sign in to your Figma account and go to the Developer Apps page
2. Click "Create new app"
3. Fill out the app details (name, description, etc.)
4. Configure your redirect URI (e.g., https://yourdomain.com/api/auth/callback/figma)
5. Note your Client ID and Client Secret

Make sure to set the redirect URI to match your application's callback URL. If you change the base path of the auth routes, you should update the redirect URI 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: {
        figma: { 
            clientId: process.env.FIGMA_CLIENT_ID as string, 
            clientSecret: process.env.FIGMA_CLIENT_SECRET as string, 
            clientKey: process.env.FIGMA_CLIENT_KEY as string, 
        }, 
    },
})

import { createAuthClient } from "better-auth/client"
const authClient =  createAuthClient()

const signIn = async () => {
    const data = await authClient.signIn.social({
        provider: "figma"
    })
}
