App actions are good to interact with your app from Pipedrive but they are kind of hidden. Therefore app panels are great because they stand out in your detail views. So I created a panel for my application and it works.
The only problem is a security one: the app panel performs a get request to my API and sends credentials as the Basic Authentication header of a HTTP request. According to https://pipedrive.readme.io/docs/app-extensions-panels#section-how-can-i-add-an-app-panel-to-pipedrive I should be able to use authenticated HTTPS requests but I don’t understand how I can change the panel behaviour to do so.
