# About Connectors

To use a connector, you often need to set up an authentication app, for example for HubSpot or Slack. This is usually required for connectors that use OAuth. Depending on the connector, different authentication methods are supported, such as OAuth or Session Auth.

For OAuth connectors, an app must always be created so users can authenticate through your credentials. Some APIs only require a basic OAuth app, while others may involve an additional review or approval process.

Before setting up a connector, please check the API documentation of the app you want to connect to in order to understand the exact authentication requirements.

Here are a few examples to help you get started.
