What is the function of the API Gateway in MuleSoft?

The function of the API Gateway in MuleSoft is to manage and secure traffic to and from APIs. An API Gateway acts as a conduit between clients and backend services, facilitating the routing of requests and responses. This allows the gateway to implement essential features like authentication, authorization, rate limiting, caching, and logging, thus providing a secure and controlled environment for API interactions.

By managing traffic effectively, the API Gateway helps in protecting backend services from overuse or malicious attacks and ensures that only compliant requests are processed. This central management point enhances overall API security and performance, providing developers with tools to enforce policies and monitor usage. Hence, this robust functionality is crucial for any API management strategy within MuleSoft’s architecture.
