Lovable: Custom Connectors for Any REST API
LovableLovable introduced custom connectors, letting workspace admins and owners on any plan add virtually any REST API to their workspace's shared connector catalog. Admins describe the target API (endpoints, credential format) and can attach optional knowledge files that teach Lovable's agent how to call it correctly. Once created, the connector appears alongside Lovable's nearly 100 built-in integrations, and any workspace member can use it in their projects like an official connector.
Key Takeaways
- Custom connectors let workspace admins and owners on any plan add any REST API to Lovable's connector catalog, not just prebuilt integrations.
- Setting one up requires describing where requests go and how credentials are structured, plus optional knowledge files that teach Lovable how to call the API.
- Once created, a custom connector becomes available to the entire workspace, not just the admin who built it.
- The feature is restricted to admins and owners, keeping credential management centralized rather than scattered across individual projects.
- It closes a gap in Lovable's catalog, which already spans close to 100 built-in connectors across CRM, billing, and messaging tools.
- Builders can now connect to a custom-built API the same way they use any official connector, without hardcoding credentials into their app.
Custom Connectors Open Up Any REST API
Lovable added a Custom connector option to its Connectors catalog, letting workspace admins and owners, on any plan, wire up virtually any REST API without waiting for Lovable to build official support for it.
How It Works
From the Connectors panel, an admin selects the + button and chooses Custom connector. Lovable then walks them through describing the target API: where requests should be sent, how it expects credentials to be passed, and optionally, knowledge files that teach the underlying agent how to call specific endpoints correctly. Once configured, the connector is added to the workspace's shared catalog.
Why It Matters
Lovable's connector catalog has grown quickly, closing in on 100 built-in integrations spanning CRM, billing, analytics, and messaging tools. Custom connectors remove the remaining gap: if a team relies on an internal tool, a niche vendor, or an API that Lovable has not built a native connector for, an admin can now add it once and make it available to every workspace member. Builders then connect to it and use it inside their projects exactly like any official connector, without re-entering credentials or explaining the API from scratch each time.
Centralizing this in the hands of workspace admins and owners also keeps credential management consistent with how Lovable already governs its other connectors, rather than leaving individual builders to hardcode API keys into their projects.
