Twitch

Beta

This feature is in beta. Core behavior is stable, but some APIs or configuration may change before general availability.

Sign in with Twitch accounts using OAuth 2.0.

1. Create OAuth App

1. Go to the Twitch Developer Console.
2. Log in with your Twitch account.
3. Click Register Your Application.
4. Fill in:
   • Name: Your app name
   • OAuth Redirect URLs: Your EdgeBase callback URL (see below)
   • Category: Choose the most appropriate category
   • Client Type: Choose Confidential
5. Click Create.

2. Set Redirect URI

Set the OAuth Redirect URL during registration:

https://your-edgebase-url/api/auth/oauth/twitch/callback

For local development:

http://localhost:8787/api/auth/oauth/twitch/callback

3. Get Credentials

After registration, click Manage on your app:

• Client ID — Displayed on the app management page.
• Client Secret — Click New Secret to generate one (copy it immediately).

4. Configure EdgeBase

// edgebase.config.ts
export default defineConfig({
  auth: {
    allowedOAuthProviders: ['twitch'],
  },
});

export default defineConfig({
  auth: {
    oauth: {
      twitch: {
        clientId: 'YOUR_CLIENT_ID',
        clientSecret: 'YOUR_CLIENT_SECRET',
      },
    },
  },
});

5. Usage

JavaScript

client.auth.signInWithOAuth('twitch');

Dart/Flutter

await client.auth.signInWithOAuth('twitch');

Swift

let url = client.auth.signInWithOAuth(provider: "twitch")
// Open url in SFSafariViewController or ASWebAuthenticationSession

Kotlin

client.auth.signInWithOAuth("twitch")

Java

client.auth().signInWithOAuth("twitch");

C#

client.Auth.SignInWithOAuth("twitch");

C++

OAuth requires a browser redirect flow. For C++ (Unreal Engine), handle OAuth in a platform webview and pass the token to the SDK.

Notes

• Twitch may require Two-Factor Authentication (2FA) on the Twitch account before app registration or sensitive app actions are allowed in the current console.
• Twitch's user info API requires a Client-Id header in addition to the Bearer token — EdgeBase handles this automatically.
• The Twitch API returns users in an array format (data[0]), and EdgeBase extracts the first user.
• Display name uses display_name if available, falling back to login (username).
• Twitch provides verified emails, so automatic account linking with existing email accounts will work.
• Local verification was completed on March 8, 2026 against http://localhost:8787/api/auth/oauth/twitch/callback using the js-web browser harness. The current result was 3 passed / 6 skipped, which is expected when the signed-in Twitch account does not unlock the password/email/TOTP checks in the harness.
