Adding TLS Certificates to REST Client

The following procedure describes how to add a client certificate in Postman, the third-party REST tool. This is required when using Mutual TLS (mTLS) authentication with the device's REST API.

➢

To add client certificate in Postman:

1.

Start your Postman application.

2.

On the toolbar, click the grid icon, and then from the drop-down menu, choose Settings.

3.

Select the Certificates tab.

4.

Click Add Certificates, and then do the following:

a.

In the 'Host' field, type the device's IP address (or hostname).

b.

Select the CRT file and the Key file for your certificate.

c.

Click Add.

5.

For your URL endpoint:

a.

Make sure that the URL endpoint is "https" (not "http").

b.

Click the Authorization tab, and then from the 'Auth Type' drop-down list, select No Auth.

Once you've add the trusted root certificate to the device, your REST requests through Postman are seamless, eliminating any need to provide username and password.
