Required Certification Testing

Certification testing is a required phase of implementing the cnpAPI format. During the certification testing, a Worldpay, Inc. Implementation Consultant works with you to verify that your transaction submissions meet the requirements of the cnpAPI specifications. Each transaction type has specific test scenarios that use specific data sets simulating real transactions. The Worldpay eComm Certification environment responds to each submission with an XML response message, allowing you to verify that you have coded correctly to parse and store the transaction data returned to you. For more detailed information, see Performing the Required Certification Tests.
