In software development, microservices and APIs are used for writing business logic. API testing has become an important component in the testing cycle, as it can be used to test the functionality, integration flows, load and performance.

In this course, you will learn how to perform REST and SOAP API test automation. This course covers all the required details for you to start writing API and integration tests from scratch. It will also prepare you for test automation interviews.

As part of the course, you will be able to download a sample API automation framework. You can use this for writing automation tests of modules or applications, or just extend and customize it for your own use

### What is REST?

REST, or Representational State Transfer, is an architectural design that defines a set of rules for creating web services that interact between systems. Web services that follow this architecture are termed, 'RESTful web services'. 

At a very high level, the RESTful system consists of two major components:

- A server that hosts the resources

- A client that connects to the server to fetch the resources 

REST uses **HTTP** (*Hypertext Transfer Protocol*) or **HTTPS** (*Hypertext Transfer Protocol Secure*) to exchange data between client and server using HTTP methods -- _GET_, _POST_, _UPDATE_, _DELETE_, _HEAD_, _PATCH_, etc.  

### Benefits of using REST

By following the principles of REST, we can benefit from the loose coupling between the server and the client, reliability, scalability, and better performance of the application. Few of the benefits of REST are listed below:

- **Simplicity** -- REST web services are easy and simple to develop compared to SOAP web services

- **Light-weight** -- REST advocates simple communication with the server over HTTP that supports plain XML, JSON formats in comparison to SOAP which supports only XML

- **Architecture is similar to Web** --the architecture of REST is very similar to how the web is designed. So, developers who understand the web can easily understand and develop RESTful web services

- **Scalability** -- the REST architecture advocates refraining from the conversational state that allows us to easily add multiple instances of the components or application behind load balancers
