When integrating payment solutions into an online project, it’s important to first define which methods your customers actually need—cards, e-wallets, crypto, or bank transfers. After that, choose a provider with transparent documentation and flexible APIs. Many users recommend starting with a
White Label PSP, as it allows you to customize the interface and manage transactions under your own brand. Don’t forget testing: run sandbox payments, verify webhook stability, and ensure proper security settings before going live. This approach helps avoid errors and speeds up integration.
