A modest Zoho CRM API client which will do the oAuth2 for you.
from zoho_client.zoho import ZohoClient
client = ZohoClient()
# GET all Sales_Orders
res = client.make_request(api_endpoint="Sales_Orders")
# res is an instance of requests.Response
for sales_order in res.json()['data']:
print(f"sales order #{sales_order['id']}")
# find the first record
sales_order_id = res.json()['data'][0]['id']
# update the sales order's subject
payload = {'data': [ {'Subject': 'CHANGED'}]}
# the make_request accpet any kwargs which the requests.request() method accpets
res = client.make_request(method='PUT', api_endpoint=f"Sales_Orders/{sales_order_id}", json=payload)
print(res.json()['data'][0]['status'])
# => success
# search for a record. the params are automatically encoded
res = client.make_request("GET", "Accounts/search", params= {"criteria": "(Account_Name:equals:Guy Moller)"})
print(f"found {resp.json()['info']['count']} records")
# create a record
account_data={'Account_Name': 'John Doe', 'Email': 'joe@example.com'}
res = client.make_request(method='POST', api_endpoint='Accounts',json={'data':[account_data]})
print(res.json()['data'][0]['details']['id'])
