Roblox authentication

Roblox authentication lets your users sign in with their Roblox account.

Setup in the Roblox dashboard

1. Open the Roblox creator / developer dashboard for your account or group.
2. Create an OAuth application (or an equivalent app configuration).
3. Add a redirect URL (the URL Roblox sends users back to after login).
   • Use the WeWeb callback URL: the address of your app followed by /api/auth/callback/roblox. The table below lists the URLs to add.
4. Copy the credentials Roblox provides (for example Client ID and Client Secret).

Add one callback URL for each place where users sign in:

Where users sign in	Callback URL to add in Roblox
Editor	https://<your-project>-editor.weweb.io/api/auth/callback/roblox
Staging app	https://<your-project>-staging.weweb.io/api/auth/callback/roblox
Published app	https://<your-project>-production.weweb.io/api/auth/callback/roblox
Custom domain	https://your-domain.com/api/auth/callback/roblox

Replace <your-project> with your project's WeWeb subdomain. You can see it in your browser's address bar when the editor is open, for example bright-harbor in https://bright-harbor-editor.weweb.io.

CALLBACK URL VS SUCCESS PAGE

Roblox always sends users back to the callback URL, never to a page of your app. WeWeb then completes sign in and takes users to the Success Page, Error Page, or New User Page you choose in the Sign in with social provider action. Do not add the URL of these pages in Roblox.

Connect Roblox in WeWeb

1. In the WeWeb editor, open the Data & API tab, then open the Authentication subtab and go to SSO Providers.
2. Select Roblox and turn on the Enable toggle.
3. Paste your credentials into the fields shown in WeWeb.
4. Click Save.

Test sign in

1. Add a “Continue with Roblox” button in Interface.
2. Create a workflow on click and add Sign in with social provider.
3. Set:
   • Provider: roblox
   • Success Page, Error Page, and (optional) New User Page
4. Preview and complete the sign-in flow.

Common pitfalls

Redirect URL mismatch

Make sure the redirect URL in Roblox exactly matches the WeWeb callback URL ending with /api/auth/callback/roblox (no trailing slash), not the Success Page URL you selected in WeWeb.

FAQs

Which redirect URL should I add in Roblox?

Add the address of your app followed by /api/auth/callback/roblox, for example https://your-domain.com/api/auth/callback/roblox. Add one for each place where users sign in (editor, staging app, published app, custom domain). The URL of your Success Page is not the redirect URL.
