Dropbox oAuth2 auth process fails with 400 Bad Request when call /oauth2/token
I have got the problem with my app.
It worked fine for long time and now somethign happend. I can not understand what is wrong here.
The problem is with oauth2 auth process.
The first step ...
Ok. Other possible reason of my problem is that there was wrong User-Agent string n the request (second line from bottom)
I seems found the reason .
My endpoint to do the second step was
https://api.dropboxapi.com/oauth2/token
when i replaced it to
https://www.dropboxapi.com/oauth2/token
all wtarted to work fine.
before it worked. maybe that endpoint support for oauth2 was canceled at some point and i didn't notice
