Social Provider Setup

The next step requires a callback URL, which looks like this: https://<project-ref>.supabase.co/auth/v1/callback

• Go to your Supabase 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 Supabase CLI, ensure your OAuth provider is configured with the local Supabase 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 Supabase CLI see the local development docs.
