What is an API gateway?
An API gateway is a management tool that sits between a client and a collection of backend services. An API gateway acts as an entry point for clients, which accepts application programming interface (API) calls. In short, an API gateway facilitates client requests and handles matters such as authentication.

API stands for application programming interface, an interface that allows for the communication between two devices, databases, or applications. A payment gateway API is integrated with other digital processes to connect a checkout system to a payment network.
2. An example of an API gateway
One example of an API gateway is Netflix, which is available on many different types of devices, such as televisions, set-top boxes, smartphones, gaming systems, and tablets. The Netflix API gateway runs client-specific adapter code that provides each client with an API that is best suited to its requirements. The codes handle requests to their respective devices on average six to seven backend services and can amount to billions of requests per day.
3. How does a payment gateway API work?
A payment gateway API relays a message or request from clients to the API, which then submits the message to payment processing networks that process the request and respond to the API, which then relays the response back to the user through the same route.
4. How do I use an API gateway?
To use an API gateway, you must first integrate it into your system.
5. Why is an API gateway required?

6. What does an API payment gateway do?
An API payment gateway integrates with existing digital processes and connects merchants' checkout systems to a payment acquiring network.
7. What is the purpose of an API gateway in microservices
An API gateway acts as a single entry point for all clients and interprets their requests to a group of internal microservices. An API gateway in microservices is responsible for request routing, composition, and protocol translation.

Advantages of an API gateway
1. What are the benefits of using an API gateway?

2. What is the difference between an API and an API gateway?
API stands for application programming interface, which is a set of codes that allows communication between two devices, databases, or applications. Meanwhile, an API gateway acts as an entry point for clients, which accepts API calls to facilitate clients' requests and handles matters such as authentication.
