Bigin API Token Request ("invalid_client")

Bigin API Token Request ("invalid_client")

Hi people,

I tried to connect to the API without success, I've read all of the documentation multiple time and tried just about everything. I tried to do it with Python Request module and with Postman, passing the information through both the URL parameter and through the form data. All i get is "invalid_client" every time. I am using the self client and I tried multiple times to generate the id/secret/code. I am in North America so I passed this information to 'https://accounts.zoho.com/oauth/v2/token' in the 2 methods mentioned before. Am I missing something? It seemed pretty straight forward. At this point the only thing I haven't tried is to make an entirely new account to see if its something that got screwed up in the account creation process.

client_id = '1000.XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
client_secret = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
code = '1000.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
grant_type = 'authorization_code'

https://accounts.zoho.com/oauth/v2/token?client_id={client_id}&client_secret={client_secret}&grant_type={grant_type}&code={code}"

Edit: Tried with a new account, same error. So that is ruled out as well.
