POSTMAN API TESTING - The Complete Guide

Learn how to create an API request in Postman, using HTTP methods like GET, and fetch data from an endpoint with a 200 response.

Learn how post, put, and delete methods create, update, and remove resources using Postman, with practical examples and response codes 201, 200, and 204.

Organize, save, and manage API requests with Postman collections, grouping related APIs, setting common authorization, and using pre-request scripts, tests, and a collection runner to share and export collections.

Explore how Postman workspaces organize collections, environments, mock servers, and documentation to boost collaboration and efficiency in API testing, with templates and cloud sync.

Learn how to apply authorization in Postman by using basic authentication, barrier token authentication, or no auth, configure authorization headers, and test APIs effectively.

Learn how to use bearer tokens in Postman to authorize API requests, including adding the token in the authorization header, handling 401 errors, and validating a 200 response.

Learn to parameterize requests in Postman by using environments and variables for base URL, email, and password, enabling seamless testing across development, staging, and production.

Learn how to create and use global variables in Postman to store base URL and credentials across requests. Extract tokens from responses and apply them in headers.

Learn to create first tests in Postman by writing pre-request and post-response scripts, validating status codes like 200 and 401, checking response times, and asserting user data from JSON.

Learn to write Postman assertions to validate API responses in real time, checking id, email, first name, and last name via pm.response.json and pm.test.

Discover how to use pre-request scripts in Postman to run JavaScript before sending a request, setting variables and generating dynamic values like a unique request ID.

Learn data driven testing in Postman by running a login API against CSV data, capturing tokens, and validating a 200 response with data driven iterations.

Learn to perform data-driven testing in Postman by using a json file with collection runner to run multiple login requests and validate tokens and responses.

Learn data driven testing in Newman using a CSV file to run a Postman collection with different input data, iterating across multiple scenarios and generating a report.

Chain requests in Postman by extracting the access token from login responses and using it in subsequent requests, saving tokens to the environment for automated API testing.

Learn to create and use a mock server in Postman to simulate API responses with predefined data and example-based status codes.

Learn to skip Postman requests based on API responses, running the next step only when login succeeds or the status code equals 200, using post response scripts.

Master running Postman collections from the command line with Newman, export collection, install Node and Newman, run the collection, and generate an HTML report.

Learn to generate an html report for Postman tests with Newman and the html extra reporter by exporting a collection, installing Newman, and running with the html extra reporter.

Postman monitors run your collection automatically to test APIs and check uptime. Configure monitors with environments, schedule hourly or daily runs, and receive email alerts.

Master debugging in Postman by inspecting login requests, tokens, and response logs using the Postman console, environment variables, and dev tools.

Learn to run Postman API collections remotely by sharing a URL, execute them without local Postman, and use Newman for remote execution in CI/CD pipelines.
