Retrieving invoices via the API - error This user is not associated with any organization

Hi,

I am trying to retrieve invoices for a particular company. If I use this request:

GET https://invoice.zoho.com/api/v3/invoices HTTP/1.1

User-Agent: Fiddler

Content-Type: multipart/form-data

Host: invoice.zoho.com

Content-Length: 0

Authorization: Zoho-oauthtoken 1000.8eb42651497dc8d0859bfad74af4753f.0a863a2dccddb0d7375df14fe4xxxxx

X-com-zoho-invoice-organizationid: 3229705000005137583

I get this response:

{"code":6041,"message":"This user is not associated with the CompanyID/CompanyName:3229705000005137583."}

As far as I know that org id is valid, but I don't understand what user they are referring to.

How do I get this to work?

Thanks in advance.

Vernon,
