Retrieving invoice with REST v3 don't exist

Retrieving invoice with REST v3 don't exist

Hi,

I'm new to zoho API, and I'm developing an application that GETs invoices. I can retrieve invoices through /invoices, but while trying to retrieve the details of one invoice I get the error 1002: Invoice doesn't exist.

I'm using this uri:
https://invoice.zoho.com/api/v3/invoices/1234500000098765?authtoken=343045xxxxxxxxxxxx&organization_id=xxxxxxx

1234500000098765 is meant to be invoice_id. It exists because I get it with /invoices. So, what I'm doing wrong?

Thanks
