Course Description
This course provides a comprehensive introduction to API authorization testing using OAuth in Postman. Throughout the course, you will gain an in-depth understanding of the fundamental concepts of OAuth, including its different flows and uses. You will learn how OAuth is applied in various real-world situations, such as backend applications, single-page applications, and mobile apps.
The course also provides hands-on experience with using different OAuth flows and how to create requests using Postman. You will work with different real-world APIs and learn to use Postman to send requests and validate the responses.
In addition to the theoretical aspects of OAuth 1.0 and OAuth 2.0 and their practical application, the course also covers testing. You will learn how to test OAuth flows and APIs using Postman, and gain the knowledge and skills needed to test and debug your OAuth-secured APIs effectively. This course will provide you with a solid foundation for working with OAuth and APIs in a practical and efficient manner.
Here are some of the topics that we will do in this course:
Token-based authentication (JWT token)
OAuth 2.0 Authorization Code grant
OAuth 2.0 Implicit Code Grant flow
OAuth 1.0 flow with the Flickr API

I teach IT professionals what I wish I'd known earlier.
My foundation is built on years in the trenches as an Agile Enterprise Software Developer, engineering solutions for everything from fast-paced start-ups and SMBs to large global corporations. I hold recognized roles as an AWS Community Builder, Postman Supernova, and GitLab Hero, alongside a deep history of securing and building major open-source projects.
For over a decade, I've taken that real-world experience and quietly built one of the largest learning communities around API tooling, test automation, and DevOps practices. What started as a side YouTube channel turned into hundreds of thousands of learners, conference talks, and team workshops at companies most IT professionals have heard of.
The thread through all of it is the same: take something that looks intimidating and break it down so anyone can understand it in plain language.
Lately, I've been spending more time on practical AI in the workplace. I look at how teams can leverage AI for both everyday knowledge work and hands-on IT engineering, like coding and testing. I focus on cutting through the hype to figure out how AI actually helps IT professionals get work done, build, and ship faster. New formats, same approach.

By Leon Porter on 3/2/2026
Course was great however Flickr now requires a paid pro subscription to be able to follow along with the tutorial for oauth 1.0

Great! What more can I say :-) It's super important to follow through all the examples and test out stuff yourself with Postman.
By Kenneth Lee on 1/10/2024
Great overview of oAuth with oAuth2 and oAuth1 real life example. See how this really works was very helpful.
By David Noguera on 8/21/2023
It is a great resource, he does an amazing job at explaining such a apparently complex subject
By Ahmed Hussain on 9/1/2020
Very good explanation of the tool and walks you through the example step by step.
By Madhu Akhilesham on 9/1/2020
Good example and explanation of API and postman
By Praveen Subbarao on 7/20/2020
Really good walking slowly thru the steps. The steps involved in chaining the requests by parsing is key and most common usecase that we run into - thanks praveen
By Kris Cruickshank on 6/25/2020
I am finding it a bit simple. I would like to know what the auth actually did. So far I have just watched an advert for postman. I want to learn about oauth
