Having lost a whole week while trying in vain the use the Zoho Books API, and an even worse technical support from Zoho, I thought I post it here, to see whether anyone has a solution:
I am trying to use the Zoho Books API for updating a simple contact, and keep getting an error like
{- "code": 7,
- "message": "Invalid value passed nnnnnnnnnnnnnnn for contact_person_id"
}even though its a correct contact_person_id, and it's included both in the PUT request URL
as well as in the param "JSONString".
As I said, the Zoho Books support is useless. Can anybody share some insight here?
This particular API is strange enough as is, requiring the contact_person_id both the URL as well as inside the JSONString param, this kind of a software design doesn't inspire confidence.
Also, is there any PHP library and better documentation for the Zoho Books API?
