What is API Proxy? An Introduction to Basic Concepts

API Proxyis an intermediary that sits in front of an application programming interface (API). Its primary function is to receive requests from clients, forward them to the API server, and send responses back to the clients from the server. This process provides additional layers of security and management capabilities by preventing direct exposure of the API. API Proxy With it, your API's performance can be optimized, security can be increased and usage statistics can be easily tracked.

One API Proxy, essentially acts as a reverse proxy. It relieves the API server by routing incoming requests, performing load balancing, and caching. This way, the API server can focus solely on business logic and work more efficiently. Also, API Proxycan also be used to manage different versions of your API and phase out older versions.

API Proxy Types

• Redirect Proxy
• Load Balancing Proxy
• Caching Proxy
• Security Proxy
• Conversion Proxy

API Proxy's are usually integrated with firewalls and authentication mechanisms. This allows only authorized users to access the API and provides additional protection against malicious attacks. For example, API ProxyBy checking the IP addresses of incoming requests, it can block requests from specific addresses or reject requests that are not associated with a specific user ID.

API Proxyprovides valuable data for monitoring and analyzing API usage. Metrics such as which API endpoints are used and how often, which clients are sending the most requests, and average response time, API Proxy This data is important for improving the performance of your API and guiding future development.

Benefits of API Proxy: Why Should You Use It?

API Proxy There are many important benefits to using it. As communication between applications and services becomes increasingly complex, API Proxies play a critical role in managing this complexity and ensuring security. An API Proxy acts as an intermediary between the API server and the clients, routing, transforming, and securing requests.
