Those params are for the OLD auth mechanism - the new one uses a different method and much newer app version.
It’s possibly you have an OLD account that is still using the OLD api calls. The script I posted in the github ticket confirms.
I just need to install pyvesync and add some select print statements to see the syntax it’s using. It’s just a matter of having enough time in the day.
I added debug infos to my script to get the full header, body etc. may this help 
My accound was created 1 week ago so it should be with the new auth mechanism.

Thanks that’s just what I need! Will see if I can get a token this evening my time.
Edit: wont’ be tonight - I’ve mapped out the differences in the difference JSON requests - ie which components ones are common to all requests and which ones are specific - but I had a big day at work, so won’t get to actually coding it tonight.
All right, thank you very much for taking the trouble to get this stuff working so quickly.
Any news? Something I can help?
Anything we can do to help?
Paul seems to be very busy - I don’t see any progress in the last 2 months… I don’t know who is the “owner” of the binding or how to find the solution for this problem.
