Hello, you can choose one of two integration methods: hosted payment gateway and payment system integration via API. Each has its own advantages, disadvantages and features. Hosted, that from your site the client will be redirected to the payment service platform. It is very simple, convenient, the integration of payment systems takes no more than 3-4 days. Integration with the payment system using the API allows you to connect the necessary tools directly to the site. The business owner is automatically responsible for the security of personal data storage and the payment process. Therefore, the site must meet the PCI DSS security requirements. This increases the company's infrastructure maintenance costs. But the store fully controls each transaction, maintains a customer database, and payment processes are easily customized to the needs of the company. Payment becomes simple and understandable, and most importantly, safe. For companies that rely on brand development and user experience improvement, this is a great solution. I can recommend that you contact the company at
