Integrating Payme with UnionPay has been a game-changer for my e-commerce business, especially after seeing how it boosted sales during last year\it\UnionPay\if you\simulate transactions with dummy cards to catch glitches like incorrect currency conversions or timeout errors. One pro tip: double-check your callback URLs and IP whitelisting to prevent security blocks. And if you\re dealing with high volumes, optimize for mobile responsiveness since a huge chunk of UnionPay users pay via apps. Allocate a weekend for this, keep documentation handy, and you\ll be live in no time.
