Postman and Swagger for API

Course Overview:

RESTful APIs (or simply REST API) are everywhere nowadays but at the same time they are getting more complex to get started with: different HTTP methods, headers, cookies, dealing with file uploads or authentication with api keys, tokens, OAuth and so much more. Postman allows you very quickly create a request with the required HTTP method and parameters, submit the request and easily inspect the results. The Open API Specification (often called “Swagger”) is currently the most popular way to create definitions of RESTful APIs. With these definitions, you can create sophisticated, auto generated documentation, generate SDKs in several languages, and do automated testing. Swagger is a set of open source tools that use these Open API Specification definition files

Course Objectives:

Participants will learn how to:

• Create GET, POST, PUT, DELETE request
• Understand GET vs POST request method
• Work with real-world APIs (Github API, Trello API)
• JavaScript basics for tests
• Write API tests in Postman
• Use data from Excel files (CSV) or JSON
• Use Postman variables to create workflows and scenarios
• Run API tests with Newman in Jenkins, GitLab CI or TeamCity
• Use OAuth2, API keys, tokens, JWT, basic auth
• Test file uploads
• Use mock servers
• Collaborate using Team Workspaces
• Read and write Open API Specification (Swagger) files to define and document APIs
• Use Swagger tools to edit files, create documentation, and create SDKs
