 Secure Sockets Layer (SSL) certificates are a way of authentication for some servers using the SSL encryption protocol. These certificates provide secure, encrypted communications between a client and a server. If you're submitting sensitive data such as passwords or payment information, these certificates are often used in testing and development environments to provide a layer of security for an API. ![](https://blog.postman.com/wp-content/uploads/2017/12/HTTPS_icon.png) If a server requires this type of client authentication, the client is required to send the associated SSL certificate along with any requests. Using the [Postman native apps](https://www.postman.com/downloads), you can view and set SSL certificates on a per domain basis. If you're using HTTPS in production, this allows your testing and development environments to mirror your production environment as closely as possible. When you add a client certificate to the Postman app, you associate a domain with the certificate. This means that for all HTTPS requests sent to this configured domain, the certificate will be sent along with the request.

Make sure you’re using `https` so the client certificate is sent along with the request. In the console, inspect the certificate that was sent along with the request.
