I'm using Postman to update a time entries to have a status of "Invoiced".

When I send: https://books.zoho.com/api/v3/projects/timeentries/1872928NNNNNNNN?organization_id=6NNNNNNN With a JSON string of {"billed_status": true} I get this error { "code": 5048, "message": "You cannot make any changes to the data that have been fetched from Zoho Projects. However, you can choose to edit this data directly from Zoho Projects."}

I don't see anywhere to edit the invoice status in Zoho Projects. Should I use APIs with Zoho Projects instead of Zoho Books?
