Postman is a popular API development and testing tool that allows developers to easily create, test, and manage APIs. Recently, I attended a Postman API workshop at my college Sahrdaya College of Engineering and Technology and wanted to share my experience and learnings with you.
The workshop was conducted by a Postman expert and 2nd year student of our college Joel and was divided into two parts. The first part focused on the basics of API development, while the second part was a hands-on session where we got to create and test our own APIs using Postman.
During the first part of the workshop, we learned about the following topics:
What is an API and why is it important?
HTTP request methods (GET, POST, PUT, DELETE)
API endpoints and parameters
API authentication
API documentation
The instructor provided examples and explained each topic in detail, making it easy to understand even for beginners like me.
In the second part of the workshop, we got to create our own APIs using Postman. We started by creating a simple API endpoint that returned a list of users. We used the mock server feature in Postman to simulate the server response, making it easy to test our API without having to set up a server.
We tried some practical's by entering our information and entering the information of our favourite book using post endpoint and obtained all information by using get endpoint.
Next, we added more functionality to our API, including the ability to add, update, and delete users. We also added error handling to our API, so that it returned meaningful error messages if something went wrong.
Finally, we learned how to document our API using Postman's built-in documentation feature. This allowed us to generate API documentation that was easy to read and understand.
Overall, the workshop was a great learning experience. I learned a lot about API development and how to use Postman to create and test APIs. The instructor was knowledgeable and made the workshop fun and engaging. If you're interested in learning more about API development, I highly recommend attending a Postman workshop.
