My course on REST API will teach you all essential aspects of REST API. Coding of REST API in NodeJs/Java is pretty straightforward and have become trivial compared to other aspects that an API provider must consider.
This course covers all aspects of REST API from end to end perspective .... not just coding. You will learn how the popular API providers are creating and managing their REST API.
There are 6 sections in the course:
1. Setting the stage
Lectures in this section will provide the outline of the course, discuss a case study (ACME Travel) that will be used as an example through the course, provide a list of tools used in the course.
2. REST API Concepts
Lectures in this section will cover the foundational concepts such as the evolution of RESTful API and the 6 architectural constraints.
3. Designing the REST API
Focus in this section is on best practices for designing the REST API. The approach taken in this section is to show how some of the popular API providers (E.g., Twitter, Facebook, Twilio ...) have designed their REST API. Some of the RESTful design aspect covered in this section are:
Resources, CRUD implementation
Error Handling, HTTP status codes
Change management & Versioning
Pagination, Partial responses
To demonstrate the implementation aspects, a set of NodeJS based API is also implemented for a fictitious enterprise ACME Travels.
4. Securing the REST API
Commonly used BasicAuth standard is not the best way to implement API security. In this section student will learn the commonly adopted Authentication and Authorization schemes used for REST API
Tokens (Jason Web Tokens or JWT)
Key/Secret
OAuth 2.0 (Using Spotify implementation as a reference)
When an API is exposed by an enterprise to the public internet, it poses a risk to the enterprise as hackers may use the vulnerabilities in the API to launch attacks against the enterprise. There are multiple types of such Functional attacks that the API provider must consider. You will learn about the common attacks and the best practices for protecting the API.
5. Swagger 2.0 / Open API Initiative specifications
This section will begin with the description of Collaborative specifications development process & benefits of adopting contract first approach. Students will learn
Swagger 2.0 specification standard
How to create REST API specifications in YAML format
Tools options for Swagger specs editing
Benefits of Swagger 2.0
Demonstration of how specifications are leveraged by common platforms such as Apigee, Mulesoft & IBM API Connect
As part of the lectures, a complete specification will be created for ACME Vacations. At the end of this section student will be able to write Swagger/OAI specifications for their own API.
6. API Management
API management is the process of publishing, documenting and overseeing application programming interfaces (APIs) in a secure, scalable environment. Lectures in this section cover the details of the following activities that an API provider carry out within the scope of API management.
Lifecycle management
Developer productivity
Developer portal
Security
Traffic management
Analytics
Productization
Monetization (API Economy)
APIgee, IBM API Connect & Mulesoft platforms will be used for demonstrating the various API management aspects discussed in the lectures. Students are encouraged to try out these platforms on their own to get a good feel of what API management platforms bring to table. The three platforms offer a free trial version that can be used for testing.
