Create REST API Credentials

Using the Zoho Developer Console, create a new Self Client application. The Zoho Developer Console is not part of the regular interface. Once logged in do a google search to find it and it "knows" about your login - credentials generated are for the logged in account.

Using Postman or a similar application, create a request as follows:

URL: https://accounts.zoho.com/oauth/v2/token

Type: POST

Parameters:

grant_type = authorization code

client_id =client id from Step 1 above

client_secret = client secret from Step 1 above

code = value from 'Generate Code' step

Use the 'Generate Code' action to create a new grant token or code.

Execute the prepared request.

Be sure to enter code and run before grant token expires.
Capture client_id, client_secret, and refresh_token values from the request. These values will be needed when configuring BillMax.
