Message-Level Validation

Message-level validation (MLV) is a script-based field-level validation against

Visa Acceptance Solutions

specifications.

Your PTP uses amount-based test triggers to send transactions to a test environment and the Visa Certification Management System for decryption. The test results are XML or RESTful output,

Business Center

test transactions, and log prints.

Visa Acceptance Solutions

uses these tests to validates the results:

Cross edit checks
Data element validation
Interchange compliance
Data mapping validation
