Payment evidence

A payment is an event attached to an immutable invoice. It does not rewrite document history and cannot set an arbitrary “paid” status.

Outgoing invoice - AR

Use the outgoing invoice /payments collection to list or record evidence and /{paymentId}/void to void it. Active payments cannot exceed the frozen outstanding amount. If the Tax Administration already accepted a collection report, voiding creates the required negative correction; an unknown reporting outcome blocks the void until reconciliation.

Incoming invoice - AP

Incoming payment evidence is the buyer's internal AP record. Klik Račun binds customerOib to the API client; the event is not sent as the supplier's AR report.

Supported methodCode values are TRA, GOT, KAR, POU, KOM, ASI, and CES. PAYMENT_PARTIALLY_FULFILLED and PAYMENT_FULFILLED are derived from active amounts and the remaining balance.
