Hello Team,

We are unable to use the Zoho Books API from our registered application.

We’ve already:

• Created a client in Zoho API Console using  (Admin in Books)

• Generated the OAuth code and token successfully

• Used the correct scopes: ZohoBooks.fullaccess,ZohoOauth.userinfo.READ

However, when we make even a simple API call like:
GET https://www.zohoapis.in/books/v3/organizations

We get this response:
{"code":57,"message":"You are not authorized to perform this operation"}

We’ve ruled out client ID, scopes, and user role.

Please confirm if API access is provisioned for Zoho Books in our org:

• Owner/Admin

Thank you,
