WTF with your documentation?

WTF with your documentation?

Hi, i have trouble, with post new contacts in zoho crm
but for first why you have different documentation for same operation with REST API?
example:
(where you get this token?)



2 different documentation for same operation (insert or add new contact)
we have 2 different token, and different input!
in another example you don't have validated json code for input!.




when i getting contacts, all ok, but when i want to make put, i cannot to do , because i have error


as JSON input, i using official example number 1

and example number2
also with same token i cannot retreive profiles, or other get operations!

as authorization token i using same token as get contacts!
when i generate token i using Scope=ZohoCRM.modules.all (or need specially generate token for ZohoCRM.modules.contacts?)
WTF and how to fix it? (probably i missing some details, but i do exactly as in official documentation... )
P.S in all examples i using access_token (that expire in 60 minutes).
domain only .eu, for another domains, not working,
Best regards
