FAQs

What is an API Gateway?

An API Gateway is a centralized service that acts as an entry point for APIs, providing security, rate limiting, routing, and monitoring features. It helps ensure secure and efficient communication between clients and backend services.

What are the key features of an API Gateway?

Key API Gateway features include API traffic management, protocol translation, load balancing, and a developer portal. These features provide efficient management of incoming requests, seamless communication between clients and backend services, increased productivity, and a better experience for developers.

How do API Gateways work?

API Gateways act as a buffer between clients and backend services. They can perform various complex operations, such as authentication, authorization, request transformation, response aggregation, and more, simplifying the communication process for clients and backend services. By analyzing request paths and applying routing rules, API Gateways ensure incoming requests are directed to the appropriate backend service or microservice within the ecosystem, enabling efficient request handling. API Gateways analyze backend service responses before relaying them to clients, allowing for additional processing, transformation, and data aggregation to optimize the response format and content for client consumption.

Is API Gateway a paid service?

Yes, the price depends on the number of requests and data transfers.

Can I use the API Gateway to monitor API performance?

Yes, the API Gateway in IONOS offers monitoring and analytics features that enable users to track API usage, performance metrics, and error rates and gain insights to identify performance bottlenecks and optimize API performance.

What should I do if an API request fails?

Check if the API service is running in your environment.
