Is it possible to make a payment through the catalog service?

Payment through the catalog service is usually not considered best practice, as the catalog service is responsible for storing and providing information about products or services, not for financial transactions.

Division of responsibilities:

• Catalog service — managing products, their descriptions, prices, categories.
• Payment service — processing transactions, interacting with payment gateways, security.

Attempting to implement payment through the catalog service would lead to a mixing of responsibilities, architectural complexity, and reduced scalability.

However, the catalog service can provide information about prices and available payment methods, while the actual payment can be delegated to a specialized service.

Therefore, it is better to implement payment in a separate service, and use the catalog service only for informing about products.
