Required evidence
Current Supplier Approval and Invoice & Payee Verification references whose replay, scope, amount and destination still match.
Machine result
An evidence-backed authorization decision; the product never executes the customer's underlying business payment.
No decision, no charge.
Invalid input, missing or stale required evidence, insufficient coverage, replay mismatch, source failure or an undeliverable result prevents settlement.
Limitations
- Authorization is not payment execution.
- Changed destination, stale evidence or replay mismatch stops settlement.
- Live source health and the response evidence are authoritative at request time.
