If you are developing an API, you must know about Postman. Postman is a very useful tool for testing APIs along with your team of developers. The software makes it easier to run all the necessary tests before publishing the APIs.
Postman launchpad is the collection of features that you can use right from when you open up the app. You can create individual requests, create API, API collection, and environment.
Creating API makes it super easy to develop API. Just click the ‘Create a new API’ from the launchpad and it’ll open the following dialogue box asking for the basic information regarding the API.
Enter the API name, version, Schema type, and Schema format.
Once the API is created, it’ll be listed in the sidebar. Click the API to perform actions on the API.
Create a Postman schema. To easily create APIs endpoints, it creates a test Schema by default. Change it to create the URLs as per your project demands.
After the schema is ready, generate collections by clicking the “Generate Collections” button as highlighted above.
This will generate the collections of routes. As you can see in the image below, there is a collection of task manager api.
Clicking each URL will allow you to customize your request, and send it to the server. You can change request’s parameters, send auth credentials, custom headers, body data etc.
Once the request is sent, the output returned back from the server is previewed below.
