How to ensure proper payment gateway integration with payment methods

▤ Summary

This includes not only the classic scenarios when a customer enters data directly in your form but also some electronic wallet solutions like Masterpass. This is even more important while using its express checkout functionality where a customer consents to share data without even logging into their Masterpass wallet. Other wallet providers like Apple Pay try to mitigate the risk by using payment tokens instead of actual card numbers. Some providers, like Apple Pay or Trustly, will also perform additional acceptance tests for both frontend and backend integration, domain verification, and so on. It is crucial to prepare for such cases by logging all communication with payment method APIs, so the team can perform a proper investigation.
