In a Nutshell
Before going live, thoroughly test your integration using Transactpay's sandbox tools—including test bank accounts, mobile money numbers, and test card scenarios—to simulate both successful and failed transactions.

Transactpay provides a robust sandbox environment that helps you test different payment scenarios, error states, and authentication flows before handling real money.
