REST API - Application ID is rejected


I just created my account. I attempted to read data via the REST API and received the following error message:

Error: JSON error response from server: {“code”:9000,“message”:“Application with ID xxxxxxxx does not exist”,“errorData”:{}}.status: 400

Resource settings for Get collection (GET)

Resource URL:

The real API Key is replaced by the xxxx. I have a data table called contact. Of course I copied the Application ID from the Backend page.

What could be off? Do I need to open the REST API somewhere before using it?

Thank you and best regards
