/api/v1/auth/get_api_token GET and POST mixup

I added an API key in the browser extension (using Firefox) and pressed the "Test"-button. I quickly get an 405 method not allowed error. Taking a look with wireshark I see a GET request, however the API doc states a POST request would be needed for the /api/v1/auth/get_api_token endpoint. So maybe that is the reason for the 405-error?

Trace the Firefox browser extension's Test-button request to /api/v1/auth/get_api_token and compare the request method with the API documentation. Confirm the Test action uses the documented method and no longer returns a 405 Method Not Allowed response.
