Login with Spotify

Add Spotify OAuth to your Zuvo project

To enable Spotify Auth for your project, you need to set up a Spotify OAuth application and add the application credentials to your Zuvo Studio.

Overview

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

Access your Spotify Developer account

Spotify Developer Portal.

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

Local development

When testing OAuth locally with the Zuvo CLI, ensure your OAuth provider is configured with the local Zuvo Auth callback URL:

http://localhost:54321/auth/v1/callback

If this callback URL is missing or misconfigured, OAuth sign-in may fail or not redirect correctly during local development.

See the local development docs for more details.

For testing OAuth locally with the Zuvo CLI see the local development docs.

Create a Spotify OAuth app

  • Log into Spotify.
  • Go to the Spotify Developer Dashboard
  • Click Create an App
  • Type your App name
  • Type your App description
  • Check the box to agree with the Developer TOS and Branding Guidelines
  • Click Create
  • Save your Client ID
  • Save your Client Secret
  • Click Edit Settings

Under Redirect URIs:

  • Paste your Zuvo Callback URL in the box
  • Click Add
  • Click Save at the bottom

Enter your Spotify credentials into your Zuvo project

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

You can also configure the Spotify auth provider using the Management API:

# Get your access token from https://studio.zuvodev.com/account/tokens
export SUPABASE_ACCESS_TOKEN="your-access-token"
export PROJECT_REF="your-project-ref"

# Configure Spotify auth provider
curl -X PATCH "https://api.zuvodev.com/v1/projects/$PROJECT_REF/config/auth" \
  -H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "external_spotify_enabled": true,
    "external_spotify_client_id": "your-spotify-client-id",
    "external_spotify_secret": "your-spotify-client-secret"
  }'

Add login code to your client app

The following outlines the steps to sign in using Spotify with Zuvo Auth.

  1. Call the signin method from the client library.
  2. The user is redirected to the Spotify login page.
  3. After completing the sign-in process, the user will be redirected to your app with an error that says the email address needs to be confirmed. Simultaneously the user receives a confirmation email from Zuvo Auth.
  4. The user clicks the confirmation link in the email.
  5. The user is brought back to the app and is now signed in.
JavaScript

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

import { createClient } from '@supabase/supabase-js'

const supabase = createClient('https://your-project-id.supabase.co', 'sb_publishable_...')

// ---cut---
async function signInWithSpotify() {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: 'spotify',
  })
}
Flutter

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

Future<void> signInWithSpotify() async {
  await supabase.auth.signInWithOAuth(
    OAuthProvider.spotify,
    redirectTo: kIsWeb ? null : 'my.scheme://my-host', // Optionally set the redirect link to bring back the user via deeplink.
    authScreenLaunchMode:
        kIsWeb ? LaunchMode.platformDefault : LaunchMode.externalApplication, // Launch the auth screen in a new webview on mobile.
  );
}

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.

Client

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

import { createClient, type Provider } from '@supabase/supabase-js';
const supabase = createClient('https://your-project-id.supabase.co', 'sb_publishable_...')
const provider = 'provider' as Provider

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

In the server, you need to handle the redirect to the OAuth provider's authentication endpoint. The signInWithOAuth method returns the endpoint URL, which you can redirect to.

import { createClient, type Provider } from '@supabase/supabase-js'
const supabase = createClient('https://your-project-id.supabase.co', 'sb_publishable_...')
const provider = 'provider' as Provider
const redirect = (url: string) => {}

// ---cut---
const { data, error } = await supabase.auth.signInWithOAuth({
  provider,
  options: {
    redirectTo: 'http://example.com/auth/callback',
  },
})

if (data.url) {
  redirect(data.url) // use the redirect API for your server framework
}

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

Next.js

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

import { NextResponse } from 'next/server'

// The client you created from the Server-Side Auth instructions
import { createClient } from '@/utils/supabase/server'

export async function GET(request: Request) {
  const { searchParams, origin } = new URL(request.url)
  const code = searchParams.get('code')
  // if "next" is in param, use it as the redirect URL
  let next = searchParams.get('next') ?? '/'
  if (!next.startsWith('/')) {
    // if "next" is not a relative URL, use the default
    next = '/'
  }

  if (code) {
    const supabase = await createClient()
    const { error } = await supabase.auth.exchangeCodeForSession(code)
    if (!error) {
      const forwardedHost = request.headers.get('x-forwarded-host') // original origin before load balancer
      const isLocalEnv = process.env.NODE_ENV === 'development'
      if (isLocalEnv) {
        // we can be sure that there is no load balancer in between, so no need to watch for X-Forwarded-Host
        return NextResponse.redirect(`${origin}${next}`)
      } else if (forwardedHost) {
        return NextResponse.redirect(`https://${forwardedHost}${next}`)
      } else {
        return NextResponse.redirect(`${origin}${next}`)
      }
    }
  }

  // return the user to an error page with instructions
  return NextResponse.redirect(`${origin}/auth/auth-code-error`)
}
SvelteKit

Create a new file at src/routes/auth/callback/+server.js and populate with the following:

import { redirect } from '@sveltejs/kit';

export const GET = async (event) => {
	const {
		url,
		locals: { supabase }
	} = event;
	const code = url.searchParams.get('code') as string;
	const next = url.searchParams.get('next') ?? '/';

  if (code) {
    const { error } = await supabase.auth.exchangeCodeForSession(code)
    if (!error) {
      redirect(303, `/${next.slice(1)}`);
    }
  }

  // return the user to an error page with instructions
  redirect(303, '/auth/auth-code-error');
};
Astro

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

import { createServerClient, parseCookieHeader } from '@supabase/ssr'
import { type APIRoute } from 'astro'

export const GET: APIRoute = async ({ request, cookies, redirect }) => {
  const requestUrl = new URL(request.url)
  const code = requestUrl.searchParams.get('code')
  const next = requestUrl.searchParams.get('next') || '/'

  if (code) {
    const supabase = createServerClient(
      import.meta.env.PUBLIC_SUPABASE_URL,
      import.meta.env.PUBLIC_SUPABASE_PUBLISHABLE_KEY,
      {
        cookies: {
          getAll() {
            return parseCookieHeader(Astro.request.headers.get('Cookie') ?? '')
          },
          setAll(cookiesToSet, _headers) {
            cookiesToSet.forEach(({ name, value, options }) =>
              Astro.cookies.set(name, value, options)
            )
          },
        },
      }
    )

    const { error } = await supabase.auth.exchangeCodeForSession(code)

    if (!error) {
      return redirect(next)
    }
  }

  // return the user to an error page with instructions
  return redirect('/auth/auth-code-error')
}
Remix

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

import { redirect, type LoaderFunctionArgs } from '@remix-run/node'
import { createServerClient, parseCookieHeader, serializeCookieHeader } from '@supabase/ssr'

export async function loader({ request }: LoaderFunctionArgs) {
  const requestUrl = new URL(request.url)
  const code = requestUrl.searchParams.get('code')
  const next = requestUrl.searchParams.get('next') || '/'
  const responseHeaders = new Headers()

  if (code) {
    const supabase = createServerClient(
      process.env.SUPABASE_URL!,
      process.env.SUPABASE_PUBLISHABLE_KEY!,
      {
        cookies: {
          getAll() {
            return parseCookieHeader(request.headers.get('Cookie') ?? '')
          },
          setAll(cookiesToSet, cacheHeaders) {
            cookiesToSet.forEach(({ name, value, options }) =>
              responseHeaders.append('Set-Cookie', serializeCookieHeader(name, value, options))
            )
            Object.entries(cacheHeaders).forEach(([key, value]) => responseHeaders.set(key, value))
          },
        },
      }
    )

    const { error } = await supabase.auth.exchangeCodeForSession(code)

    if (!error) {
      return redirect(next, { headers: responseHeaders })
    }
  }

  // return the user to an error page with instructions
  return redirect('/auth/auth-code-error', { headers: responseHeaders })
}
Express

Create a new route in your express app and populate with the following:

...
app.get("/auth/callback", async function (req, res) {
  const code = req.query.code
  const next = req.query.next ?? "/"

  if (code) {
    const supabase = createServerClient(
      process.env.SUPABASE_URL,
      process.env.SUPABASE_PUBLISHABLE_KEY, {
    cookies: {
      getAll() {
        return parseCookieHeader(req.headers.cookie ?? '')
      },
      setAll(cookiesToSet, headers) {
        cookiesToSet.forEach(({ name, value, options }) =>
          res.appendHeader('Set-Cookie', serializeCookieHeader(name, value, options))
        )
        Object.entries(headers).forEach(([key, value]) =>
          res.setHeader(key, value)
        )
      },
    },
  })
    await supabase.auth.exchangeCodeForSession(code)
  }

  res.redirect(303, `/${next.slice(1)}`)
})
JavaScript

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

import { createClient } from '@supabase/supabase-js'

const supabase = createClient('https://your-project-id.supabase.co', 'sb_publishable_...')

// ---cut---
async function signOut() {
  const { error } = await supabase.auth.signOut()
}
Flutter

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

Future<void> signOut() async {
  await supabase.auth.signOut();
}
