Hello! Anyone tried applying payments to invoices with installments by sending an update request for the payment via SOAP or REST?

I haven't worked on setting up installments but i hope this below tutorial will help you analyze

@bt yes, we have tried and to the best of our knowledge it is 100% unsupported via API (SOAP/REST), it's a huge pain to our clients.

Thanks Simon! I filed a case with NS but unfortunately they weren't able to provide answers too so we just opted for custom installment record.
