Method

GET

API

https://books.zoho.com/api/v3/organizations

this is my setting

Headers

Authorization Zoho-oauthtoken 1000.f494xxxxxxxxxxxxxxxxx

Return

{
    "code": 57,
    "message": "You are not authorized to perform this operation"

Answer 1

Sometimes error 57 is because the wrong server is queried.

For example, if an account is associated with books.zoho.eu but the query url is to books.zoho.com it will throw the 57 error. So check for that.
