# One callback URL for every app in your workspace

By Steven Van · 2026-08-17

Base44 connectors now share one OAuth callback URL across a workspace, replacing per-app registration, with older connections switchable on request.

Setting up a connector in [Base44](<https://creatorstoolbox.com/tools/base44>) with your own OAuth credentials used to mean registering a separate callback URL for every app host, and each new app or custom domain sent you back to register another. [Connectors now use one callback URL](<https://docs.base44.com/changelog/product#august-17-2026>) that covers every app in the workspace: add https://connectors.base44.com/api/oauth/callback to your OAuth provider once, and it keeps working as you build more apps and connect custom domains.

Connections created before this change keep their old per-app URLs and show a Per-app URLs badge. These can be switched over to the shared URL from Callback URLs in the connection, and switched back the same way.
