API Testing with Postman: Basic to Advanced with ChatGPT

Compare soap and rest api to show that restful api offers more benefits, supports multiple protocols and formats like xml and json, and uses lower bandwidth than soap.

Explore base url and endpoints in rest api, learn how the base url locates all apis and how endpoints target specific resources, with versioned paths like v1 and v2.

Understand the header and body in API requests, including sending a request with an API key in the header and the server’s authentication and response.

Explore how a client request uses an http method, header, and body to instruct the server. Learn get, post, put, delete, and patch and their roles.

Learn how API status codes signal success, redirection, client errors, and server errors, from 200 to 504, with examples like 200, 201, 202, 301, and 404.

download and install postman by selecting the Mac or Windows version, choose Apple chip or Intel chip on Mac, then create a free account and sync across app and web.

Discover how postman helps you create, test, and manage REST and GraphQL APIs through design, mocking, documentation, monitoring, and automated testing.

Explore the postman interface, including workspaces, collections, environments, and history, and learn to create requests with HTTP methods, base URLs, headers, and bodies, plus import and monitors.

Explore how to use Postman to test REST APIs, build requests with base URLs and endpoints, send GET and POST calls, handle JSON bodies, and read responses.

Master Postman collections and folders to organize, save, and manage APIs for employee data and airlines data; learn saving requests, viewing history, and using send and download for responses.

Learn how to generate API keys and tokens to authenticate access between client and server using Trello and other API documentation, with Postman workflows.

Learn how to authenticate with an api key and token, set up a Postman collection with variables, and fetch Trello boards via base URLs and endpoints.

Master performing http methods to manage Trello resources via Postman, including creating boards and cards, updating names and descriptions, and deleting or archiving items using api key and token.

Learn to use environments in Postman to switch between API versions and accounts by defining base URL variables and managing multiple environments.

Learn to use post response scripts in Postman to test status codes, response times, and JSON data. Create and run test snippets, validate headers, and interpret results.

Explore a practical SOAP API example that uses XML requests and responses, demonstrates single-parameter post interactions, and contrasts SOAP with RESTful APIs.

Master pre request scripting in Postman by using JavaScript to generate dynamic data before api calls, log results, and store values in environment variables.

Explore Postman's faker library to generate random data using dynamic variables, including names, colors, IP addresses, and phone numbers, and learn practical steps to apply it in tests.

Learn to use ChatGPT to generate a Postman pre-request JavaScript function that creates a random string from uppercase, lowercase letters and digits, with a default length and console logging.

Learn to create Postman test scripts in JavaScript that validate status codes, headers, and cookies, using ChatGPT to generate and customize checks for different responses and environments.

Automate api testing in postman from scratch by chaining requests, applying data driven testing, and using environment variables; build flow that creates, retrieves, and deletes a board with a runner.

Explore data driven automation by parameterizing tests with custom data from CSV or Excel, and run data driven tests to drive API calls.

Explore how Postman uses five variable types to manage data across environments and collections, including environment, collection, global, local, and data variables for flexible testing.

Install and set up Node.js and npm to run JavaScript outside the browser, using the terminal. Learn to verify installations with node -v and npm -v.

Install Newman globally with npm to run and automate Postman test collections from the terminal, enabling CI/CD integration and environment-specific testing across development and staging.

Master executing Postman collections with Newman on the command line, including exporting JSON collections and running them in a consistent environment, plus data-driven tests with CSV.

Install and explore Docker, understand containers and images, and learn how Docker converts projects into universal images to run across Mac, Windows, and Linux.

Run postman collections in docker using newman images across mac and windows. Manage environment variables, access keys, and sharing collections to streamline api testing.
