Supabase Third-Party Auth Integration

Clerk is now supported as a Supabase third-party authentication provider⁠. This first-class integration allows Supabase to accept Clerk-signed session tokens, removing the need to create a custom JWT template and generate a specific token when interacting with Supabase's APIs.

Now, all you need to do is pass Clerk's session token to Supabase's client:

import { createClient } from '@supabase/supabase-js'
import { auth } from '@clerk/nextjs/server'

const supabase = createClient(
  process.env.NEXT_PUBLIC_SUPABASE_URL!,
  process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!,
  {
    async accessToken() {
      return (await auth()).getToken()
    },
  },
)

Enable the integration
