The API reference isn't available right now

This instance couldn't load its API specification. The reference returns as soon as the specification is readable again.

Back to the API reference

No such model

This instance publishes no model under that name. It may have been renamed, or no operation this installation serves uses it.

Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-22 22:52 UTC.

API reference Models

TransactionDecisionNoteCategory

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

The subsystem that produced a `TransactionDecisionNote`. Seeded with `ConvenienceFee`; designed to grow (Surcharge, Tax, Avs, Cvv, Fraud, Tip, …) as other subsystems start recording decision explanations, with no new transaction fields.

Values

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
ConvenienceFee The convenience-fee evaluator (first consumer).
Surcharge The surcharge eligibility pipeline. Records why a surcharge was not applied to a transaction on an enabled merchant (e.g. debit/prepaid card, restricted state, unsupported network), so the veto reason is queryable/displayable rather than buried in the /SurchargeResult snapshot. The code is a SurchargeIneligibilityReason value name.
FraudReview The manual fraud-review hold. Records that a transaction was parked for human disposition and how that hold ended, so the timeline explains a gap between screening and authorization rather than leaving an operator to infer it from /FraudReviewData. The code is one of ReviewHeld, ReviewApproved, ReviewDeclined, or ReviewExpired.
