POST Create Invoice Process Returns 200 And process_id: 0

Apex Connect

Hello,

When posting to Create Invoice Process on my sandbox NXT Payables API, I get a 200 response with the payload:

{
"process_id": 0
}

I then attempted the same request to 'Create Invoice (Deprecated) ' and am getting a 403 Forbidden ("You dont have permissions to create invoices…").

My question is, Should I be getting the 403 with the 'Create Invoice Process' endpoint as well instead of the 'process_id: 0'?

Thanks!
