POSTMAN is a great tool for retrieving response from an API. It doesn’t require a framework, and developers and automation engineers can use it to make sure the service is up and running as well as the build version of an API that is being deployed into the area.

API stands for application programming interface. It is a set of methods that scripts or programmes use to communicate with an application or service. APIs can be found in many different places, such as websites, apps, and devices. They allow different systems to communicate with each other and share data and information. To use Postman to execute APIs, follow these steps:

  1. Open Postman on your computer.
  2. In the left-hand column, click the “APIs” tab.
  3. In the right-hand column, click the “Get Started” button.
  4. On the “GET STARTED” page, click the “Execute an API” button.
  5. In the “API Name” field, type the name of the API you want to use.
  6. In the “URL” field, type the URL of the API you want to use.
  7. In the “Method” field, type either GET or POST (depending on which method you want to use).
  8. Click OK to execute your API request. To get started using Postman’s APIs, follow these steps:
  9. Open Postman on your computer.
  10. In the left-hand column, click on “APIs.”
  11. Underneath that heading there will be a list of all available APIs which you can access by clicking on them (or using keyboard shortcuts). If there are no available APIs then this will say so at top and you can search for more by typing in keywords into Google or another search engine - alternatively there may be an event taking place which means that some APIs are unavailable at this time! If there are no available APIs then please email us at info@postmanapplicationsolutions dot com so we can add them! Once you have found an API that interests you then continue reading!

Steps to use Postman to Execute APIs

Step 2: On the left side of the screen, click on “Collections.” Step 3: Click on “Add Collection.” Step 4: Type in a name for your collection and select the type of request you would like to create. Step 5: Select the date range for your collection. Step 6: Click on “Create Collection.” ..

Step 2: On the “collections” tab, click on the “+” button to create a new collection. A new collection will appear and you will be able to edit its name, description, and many other settings. ..

Step 3: Then right click on that new collection and select “add request” to create your first request.

In this step, we will select the recently created request and enter the API endpoint where it says ‘Enter request URL’ and select the method (the action type) on the left of that field. The default method is GET but we will use POST in the example below.

  1. Use the “OAuth 2.0” authentication method to obtain an authorization token from the server.
  2. Use the “Basic Authentication” authentication method to provide your username and password directly to the server.
  3. Use the “CURL” command-line tool to obtain an authorization token from the server using a POST request with a JSON payload containing your credentials.
  4. Use the “Webhooks” feature in Postman to automatically send an authorization request to a remote server upon each change made in a project’s source code repository.
  5. Use any of Postman’s other supported authentication methods, such as Facebook, Google, or Twitter login credentials, if available on the server side. Postman supports five different methods for obtaining an authorization token from a server: OAuth 2.0, Basic Authentication, CURL, Webhooks, and any of Postman’s other supported authentication methods ..

To use the Basic Authentication feature on a website, you must provide a username and password.

Step 6: Enter headers in case they are required. ..

In order to complete the sign-in process, you will need to enter a POST body. This information will be used to create your account and set up your preferences. ..

If you wish to execute this API now, hit the ‘Send’ button. You can also click on the ‘Save’ button beside it to save that API request to your library. ..

Final Words

In this article, we will use Postman to test the REST API of a company. This API enables interoperability between software programmes by facilitating API calls. Postman is a popular API testing software that integrates easily into CI/CD pipelines.
