API access for beginners

[PatrickKiefer93]

I try to use the API of coco annotator. I am new in this topic and I do not really find a helpful documentation.
I just want to load an image and its coco annotation to coco-annotator from a python script.

But already the first command does not work, followed by error message:

{"success": false, "message": "Authorization required"}

I tried to get authorization with my limited knowledge about API and Swagger but without success.
How can I get authorization and send commands? Maybe some examples in python would be very helpful.

Thank you.
