Problem in connecting by API - scopes


I want to connect Airtable with Webflow via and API. The application offered by Make does not work so I wanted to use an HTTP Request. I created an API key and connected to Webflow to execute a simple command: GET List sites. Unfortunately, I got an authorisation error. My guess is that the problem is scopes.

How do I set up the connection to Webflow to make it work correctly?
Do I need to create an application for data authorization (Authorization)?
