ASP.NET Tutorial: How to Importing .NET Core APIs into Postman?

Craig Johnson05 mins

We can import API data into Postman API Collection with ease by using Swagger.

Copy the URL: https://localhost:7123/swagger/v1/swagger.json

Open the Postman application. If you don’t have an account, please create one and download the application.

Press the “Import” button. A popup similar to the one below will open.

Paste the copied URL in the highlighted textbox.

Click the Import Button once again in the box, It will create the collection as follows.

API Collection Highlights

We will set Authorization globally here in this tab.

In the Variables tab.

We can override the values below the image for our deployment environment settings.

  • If Development baseUrl: https://localhost:7123
  • If Testing baseUrl: https://test-api.domain.com

More details as below as an image.


While hitting the Send button (in Blue color), our endpoint will be triggered and get the API response.

The proper username and password will provide the results below.

Practical API Testing Techniques for Accelerating Development

pm.test("Status code is 200", function () {
    pm.response.to.have.status(200);
});

pm.test("Body isSuccess as true", function () {
    pm.expect(pm.response.text()).to.include("\"IsSuccess\":true");
});

pm.test("Body message", function () {
    var jsonData = pm.response.json();
    pm.expect(jsonData.Message).to.include("Login Success");
});

pm.test("Body Email Found", function () {
    var jsonData = pm.response.json();
    console.log("Value of Email in the Response Body - " + jsonData.Data.Email);

    pm.expect(jsonData.Data.Email).to.not.eql(null);
    pm.expect(jsonData.Data.Email).to.not.eql("");
    pm.expect(jsonData.Data.Email).to.be.an('string');
});

Basic scripts help developers unit-test their endpoints following the TDD approach.

In the example below, we see that the response was 200, but the email data in the response was missing, causing one test to fail.

The response below was passed with a score of 4/4.
