How do you verify client certificate authentication?

How to test client certificate authentication in Postman?

We have a client that uses client certificate authentication in a POST request to our API.

The request is created using the Postman tool, and its parameters are set automatically. We need to send this request to our API as the first step of a larger process.

I am able to create the correct JSON body, but I can't see how I would test the response for the client certificate authentication. Is there some sort of way to view the response from our API? The response should be a new line saying that the request was successful, however, I can't see it. This is what the request looks like: And this is what the response looks like: When we test this API with a hard-coded certificate, the response is as expected. This is because we use an APIKEY set in our environment, which is why I would like to automate this test so I don't have to manually insert the APIKEY each time.

Thanks! Use Postman > Open in Developer Console. Then do the testing. You're asking about Postman 4 right? If you're using it you can use Postman > Inspect > Network in the header of the web tab. It will open a developer console, where you'll find the response if any.

If it's a POST call, in most of the scenarios it's a JSON call, so it should be pretty straightforward to inspect the headers in the dev console. As of version 5.x: To see the response (even when using postman > inspect > network), you just need to hit the arrow on the left side of the network pane, click on xHR (if you're seeing the raw response of the response, just click the response title.

In Postman 5. View > Click the "network" icon in the bottom right corner. This brings up a window showing all network requests your application has sent. Select the request and hit the "inspect" button, this will take you to the http request inspector where you can check the response and headers.

How to validate client certificate in Web API?

I am trying to understand how to validate a client certificate in Web API.

) So I understand this function takes one argument (the HttpRequestMessage) and is suppose to return a string. Or how else would one do this? The AuthorizeAttribute doesn't work well with MVC, but can work well with Web API. In your Web API controller, you should return your model/action result after the certificate is validated. So, assuming that the user can obtain a trusted certificate from your web server, and that your client sends the proper certificate to the web server, then just use your normal Web API action logic for processing the request.
