In this advanced-level course, you’ll learn to create REST APIs using the Spring Framework. The course gives a detailed experience in designing, implementing, and documenting REST APIs with end-to-end features like database integration and monitoring.

Firstly, you'll set up a Spring Boot project and create fully-functional REST APIs to manage your to-do lists. Secondly, you’ll learn database integration using Spring Data JPA and consume APIs using various tools such as cURL, Postman, and the Swagger UI. Thirdly, you'll learn Aspect-Oriented Programming (AOP) in Spring and Unit test the APIs using Spring Framework. Lastly, you’ll learn to document APIs using Springfox and Spring REST Docs and monitor them using the Spring Boot Actuator. 

By the end of this course, you'll be confident to design, implement, and document REST APIs end-to-end using the Spring Framework, including advanced topics like AOP, Unit Testing, and Monitoring.

REST APIs with Spring, JPA, and Springfox

**API documentation** is the technical information about the APIs that defines the usage principles, requests, and responses. It also instructs the user on how to integrate the API and effectively use it. In simple words, API documentation is the user manual of an API. For instance, take a look at the GitHub REST API documentation.

This is a common question, often asked by API developers. There are various reasons for and benefits of using API documentation: 

* **Improves user experience**: API documentation helps users to get onboarded quickly.
* **Adopted easily**: Not only does API documentation define usage principles, but it also defines the expected request and responses to each endpoint. So, it makes the APIs easy to integrate and run tests on.
* **Brings all stakeholders to the same page**: API documentation works as a standard document for all the communication regarding the APIs among teams. So, internal and external teams can refer to the same for development, maintenance, and integration.
* **Cost-effective for development and support**: API documentation helps follow an iterative approach while developing the APIs and makes it easier for support teams to adapt.
* **Maintainability**: It makes the APIs easier to maintain by describing the features, integration techniques, and usage principles.

Let's learn why documentation is recommended for the REST APIs, and explore API documentation with Swagger and Springfox.
