# API Documentation

The **Documentation** source category enables smooth integration with popular API documentation formats, providing a clear alignment for documented APIs within the catalog. Pynt actively monitors the gateway for any changes, ensuring that the API catalog remains up-to-date with the latest information.

The supported API documentation integrations can be found [here](broken://pages/IMtSn0flOAedJ0pl4Zco).

To add an API documentation source, select the '**Documentation**' category when adding a new source from the application Actions, or simply click on '+' directly from the applications table.
