POSTMAN API TESTING - The Complete Guide

Explore post, put, and delete methods in Postman to create, update, and remove resources, with response codes 201, 200, and 204.

Organize api requests using Postman collections, create and rename collections, add multiple requests, run collections with collection runner, and share or export with teammates, including pre-request scripts, tests, and variables.

Create and manage Postman workspaces to organize collections, environments, and APIs with templates and cloud syncing. Collaborate with teammates by controlling access, sharing updates, and customizing workspace themes.

Learn how to use barrier token to securely authorize API requests in Postman, pass the token in the authorization tab, and validate responses.

Master parameterization in postman by using environments and variables to test login APIs across development, staging, and production with base URL, credentials, and headers.

Learn how to create and use global variables in Postman to store base URL, credentials, and tokens, automate login requests, extract tokens from responses, and apply them in subsequent requests.

Learn how to create and automate Postman tests with pre-request and post-response scripts, validate status codes, measure response time, and assert a users array in API responses.

Learn to use Postman assertions to validate API responses in real time by checking id, email, first name, and last name with PM.response.json and PM.test.

Demonstrates data-driven testing in Postman by driving a login API with CSV or JSON data, iterating requests, and validating a 200 response with test scripts.

Perform data driven testing in postman by running a login request across multiple data sets from a json file using the collection runner, obtaining access and refresh tokens.

Learn how to chain requests in Postman by extracting an access token from login, saving it to an environment, and using it in subsequent requests with authorization.

Create and use a mock server in Postman to simulate API responses with predefined examples, status codes, and validation scripts for testing requests.

Learn how to skip a Postman request based on an API response by conditionally executing the next call after a successful login and a 200 status.

Learn to run Postman collections from the command line using Newman, export a collection, install Node.js and npm, run the collection, and generate an html report with the Newman reporter.

Generate a custom HTML report for Postman tests using Newman and the HTML extra reporter, including exporting collections and running with the HTML extra reporter options to view detailed results.

Learn how to use Postman's monitor to automatically run a collection, test your APIs, track health, and receive email reports, with scheduling, environment support, data file input, and advanced settings.

Debug Postman requests by inspecting logs, console output, and response headers, using environments and variables (base URL, email, password) to validate login tokens and diagnose errors.

Remotely run your api collections by sharing a url. Install new main and run the collection on a remote server, enabling ci/cd workflows and quick testing without local Postman.
