What is an API Gateway?
The Role of an API Gateway
An API Gateway acts as a single entry point between your clients—such as web browsers, mobile apps, or other systems—and the many backend services your application uses. Instead of clients talking directly to each service, they send all their requests to the API Gateway. The gateway then forwards these requests to the right service and returns the responses to the clients.
This setup makes things simpler and more secure. The API Gateway can:
- Hide the details of backend services from clients;
- Control who can access which services;
- Block unwanted or suspicious requests;
- Ensure that sensitive data stays protected.
By handling these responsibilities, the API Gateway helps keep your system organized, efficient, and safe from common threats.
