@henrydatei I have just sniffed the traffic of the app. You could probably also just decompile the apk using apktool for example, a list of the apis is in base.apk/smali_classes3/de/veedapp/veed/network/StudydriveApiInterface.smali :

Thank you very much. I had the plan decompiling the app today but now that is not necessary.
Do you know how
‘‘‘
/api/app/v1/{answer_type}/answers/{answer_id}/upvote
‘‘‘
works? The answer_type is the same as the question_type (document, course) and the answer_id should be clear. But if I try a POST request with the parameter token given when logging in, I get an error („Something gone wrong“, very helpful 😂)
no idea, works for me. Maybe you didnt specify it is a POST request and it tries GET?
curl -X POST -H "authorization: Bearer ********" https://api.studydrive.net/api/app/v1/document/answers/*****/upvote
{"success":true,"rating":1,"hasvotes":true,"upvotes":1,"downvotes":0,"uservote":"up"}%
Thanks for your fast answer - for testing purposes I used curl instead of python and forgot the -X POST 🙈

is there an official documentation for the API? How do you know the functions of the API?
