Postman API Testing Fundamentals

Install Postman on your machine using the desktop app or the web version, then launch, review updates and release notes, and compare desktop versus web features.

Learn how to send your first request in Postman by creating a new GET request to Postman-echo.com and viewing the JSON response.

Learn how to send requests in Postman to connect to APIs and test functionalities. Explore CRUD operations mapped to get, post, put, and delete, with parameters, headers, authorization, and body.

Send a get request in Postman by creating a CampusConnect workspace and an eCampusConnect collection, then use a base URL variable and mock server to fetch courses in JSON.

Explore how to send a post request in Postman by duplicating a request, switching to POST, sending raw JSON data, and receiving a 201 created response.

Pass header key-value pairs to transmit metadata in http requests, while Postman adds default headers like host and user agent; override values and add content-type when needed, since headers are optional.

Explore the history tab in Postman API testing fundamentals to review past requests, view request and response details, save or mock entries, and clear history.

Learn to use Postman to send http requests for api interactions, performing create, read, update, delete operations with parameters, headers, authorization, body data, and understand request structure and responses.

Postman's code snippets generate ready-to-use client code for the current request in multiple languages, such as C-sharp, speeding API integration. It also offers language-specific settings that update the generated code.

Explore how the Postman console captures request and response details, enables filtered troubleshooting, and distinguishes console logs from history for effective API debugging.

Learn how to organize Postman API requests by creating and managing collections and folders, including saving, adding, and editing requests, and understanding collection types and uses.

Explore how Postman collections organize saved requests into folders, enable logical grouping, collaboration, API documentation, and streamlined API testing for efficient workflow.

Explore how Postman uses variables and environments to store and reuse values, group them into collections, and manage global versus environment scope for efficient API testing.

Group related variables into environments to simplify managing api requests across development, testing, and production contexts. Enable context switching and controlled access for sensitive tokens while keeping variables organized.

Create and manage environment variables in Postman, using a base url and port for all requests, and understand initial versus current values and how exporting shares only initial values.

Navigate the workspace menu to manage an existing Postman workspace—edit details, invite collaborators with a link, or leave or delete the workspace.

Import and troubleshoot api requests in Postman by importing a curl command or raw text, running the request, and inspecting headers, body, and console logs to identify root causes.
