Hi ,What exactly is the data you want to get from the API call?

Hi,

Thanks and Regards,

Hello,Does the supplier want the information in the invoice as a report, does he want the invoice_id information, what exactly is the transaction that is wanted to be done? If you provide detailed information, I can try to help you whether it can be done or not.
