: This API is part of the Legacy Fraud API framework and is maintained for compatibility with existing implementations.

Consistent request and response contracts

Use this Legacy API documentation only if:

You are maintaining an existing Legacy Fraud API integration.

You have not yet completed migration to Universal Fraud APIs.

Accertify has specifically directed your implementation to remain on the Legacy API framework.

 API is designed for transactions involving 

consumer goods and fulfillment‑oriented purchases

, built on the shared core model (transaction, account, payment, items, addresses, device signals, and so forth).

Retail implementations typically emphasize:

 (what was purchased, quantity, price, discounts)

 (shipping vs pickup patterns, address usage)

 (single tender vs split tenders, wallet vs card, etc.)

Retail clients can vary significantly (product types, checkout flows, fulfillment models). This is why the field requirement model is important: if your implementation can supply an Imperative field, you should send it consistently.

The Retail API follows the platform hashing rules. Fields designated as hash-required must be hashed before submission, including:
