Linear authentication

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

Setup in the Linear dashboard

1. Go to the Linear settings for your account or workspace.
2. Create an OAuth application (or an equivalent app configuration).
3. Add a redirect URL (the URL Linear sends users back to after login).
   • Use the WeWeb callback URL: the address of your app followed by /api/auth/callback/linear. The table below lists the URLs to add.
4. Copy the credentials Linear 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 Linear
Editor	https://<your-project>-editor.weweb.io/api/auth/callback/linear
Staging app	https://<your-project>-staging.weweb.io/api/auth/callback/linear
Published app	https://<your-project>-production.weweb.io/api/auth/callback/linear
Custom domain	https://your-domain.com/api/auth/callback/linear

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

Linear 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 Linear.

Connect Linear in WeWeb

1. In the WeWeb editor, open the Data & API tab, then open the Authentication subtab and go to SSO Providers.
2. Select Linear 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 Linear” button in Interface.
2. Create a workflow on click and add Sign in with social provider.
3. Set:
   • Provider: linear
   • 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 Linear exactly matches the WeWeb callback URL ending with /api/auth/callback/linear (no trailing slash), not the Success Page URL you selected in WeWeb.

FAQs

Which redirect URL should I add in Linear?

Add the address of your app followed by /api/auth/callback/linear, for example https://your-domain.com/api/auth/callback/linear. 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.
