Auth

Login with Figma

To enable Figma Auth for your project, you need to set up a Figma OAuth application and add the application credentials to your Supabase Dashboard.

Overview

Setting up Figma logins for your application consists of 3 parts:

Access the Figma Developers page

Figma Developers page

Find your callback URL

The next step requires a callback URL, which looks like this: https://<project-ref>.supabase.co/auth/v1/callback

  • Go to your Supabase Project Dashboard
  • Click on the Authentication icon in the left sidebar
  • Click on Providers under the Configuration section
  • Click on Figma from the accordion list to expand and you'll find your Callback URL, you can click Copy to copy it to the clipboard

Create a Figma OAuth app

  • Enter your App name, Website URL and upload your app logo
  • Click on Add callback
  • Add your Callback URL
  • Click on Save

Create Figma app

  • Copy and save your newly-generated Client ID
  • Copy and save your newly-generated Client Secret

Get Figma app credentials

Enter your Figma credentials into your Supabase project

  • Go to your Supabase Project Dashboard
  • In the left sidebar, click the Authentication icon (near the top)
  • Click on Providers under the Configuration section
  • Click on Figma from the accordion list to expand and turn Figma Enabled to ON
  • Enter your Figma Client ID and Figma Client Secret saved in the previous step
  • Click Save

Add login code to your client app

When your user signs in, call signInWithOAuth() with figma as the provider:


_10
async function signInWithFigma() {
_10
const { data, error } = await supabase.auth.signInWithOAuth({
_10
provider: 'figma',
_10
})
_10
}

For a PKCE flow, for example in Server-Side Auth, you need an extra step to handle the code exchange. When calling signInWithOAuth, provide a redirectTo URL which points to a callback route. This redirect URL should be added to your redirect allow list.

In the browser, signInWithOAuth automatically redirects to the OAuth provider's authentication endpoint, which then redirects to your endpoint.


_10
await supabase.auth.signInWithOAuth({
_10
provider,
_10
options: {
_10
redirectTo: `http://example.com/auth/callback`,
_10
},
_10
})

At the callback endpoint, handle the code exchange to save the user session.

Create a new file at app/auth/callback/route.ts and populate with the following:

app/auth/callback/route.ts

_30
import { NextResponse } from 'next/server'
_30
// The client you created from the Server-Side Auth instructions
_30
import { createClient } from '@/utils/supabase/server'
_30
_30
export async function GET(request: Request) {
_30
const { searchParams, origin } = new URL(request.url)
_30
const code = searchParams.get('code')
_30
// if "next" is in param, use it as the redirect URL
_30
const next = searchParams.get('next') ?? '/'
_30
_30
if (code) {
_30
const supabase = await createClient()
_30
const { error } = await supabase.auth.exchangeCodeForSession(code)
_30
if (!error) {
_30
const forwardedHost = request.headers.get('x-forwarded-host') // original origin before load balancer
_30
const isLocalEnv = process.env.NODE_ENV === 'development'
_30
if (isLocalEnv) {
_30
// we can be sure that there is no load balancer in between, so no need to watch for X-Forwarded-Host
_30
return NextResponse.redirect(`${origin}${next}`)
_30
} else if (forwardedHost) {
_30
return NextResponse.redirect(`https://${forwardedHost}${next}`)
_30
} else {
_30
return NextResponse.redirect(`${origin}${next}`)
_30
}
_30
}
_30
}
_30
_30
// return the user to an error page with instructions
_30
return NextResponse.redirect(`${origin}/auth/auth-code-error`)
_30
}

When your user signs out, call signOut() to remove them from the browser session and any objects from localStorage:


_10
async function signOut() {
_10
const { error } = await supabase.auth.signOut()
_10
}
