My own Code

def authenticate_crm():

"""
access to response object id:
response_object.get('data')[0].get('details').get('id')
"""

url = 'https://accounts.zoho.com/oauth/v2/token'

headers = {
    'Content-Type': 'application/x-www-form-urlencoded'
}

# one time self-client token here -
request_body = {
    "code": "1000.aa8abec144835ab79b8f9141fa1fb170.8ab194e4e668b8452847c7080c2dd479",
    "redirect_uri": "http://example.com/yourcallback",
    "client_id": "1000.H95VDM1H9KCXIADGF05E0E1XSVZKFQ",
    "client_secret": "290e505ec52685fa62a640d874e6560f2fc8632e97",
   " grant_type": "authorization_code"
}

response = requests.post(url=url, headers=headers, data=json.dumps(request_body).encode('utf-8'))
if response is not None:
    print("HTTP Status Code : " + str(response.status_code))
    print(response.json())

I am essentially struggling to convert the Postman API request to a Python request to get the token as part of the workflow. What am I doing wrong here?

The documentation states: Note: For security reasons, pass the below parameters in the body of your request as form-data. (access-refresh link) but passing it in postman as form-data breaks the call completely.

According to their own documentation (which is convoluted, contradictory and full of outdated screenshots) the authentication key is needed only once. Once the request from above runs, I would take the response in the third image and use the refresh key to add the contact. I am also open to a solution with the SDK 3.0.0, if anybody can help.
