Postman is an API platform used by developers to test API calls. It is a powerful tool that we can use to build and design APIs.

Examples

GET Request

Let’s fetch the FA23 AppDev Roster: https://ioscourse-g3jtiqqehq-ue.a.run.app

This is a GET request that does not take in any query parameters or request body. You can also see the status of the request (”200 OK”).

POST Request

Let’s add a new member to the roster:https://ioscourse-g3jtiqqehq-ue.a.run.app

This is a POST request that takes in a request body in the above JSON format. The server responds with a 200 status code and the member that we added.

If we tried to provide an invalid request, then the server responds with a 400 Bad Request status code and an error message.
