How to establish a secure connection to the API via TLS?

Question

API

You need to send a request to the API via https. Tell me how to do it?
I use postman for testing, I found a tab where you can add a certificate. In the documentation, I was given a link only to a certificate (.cer) from which I could not get the key.

Answer 1

Have you received a UC certificate? So put it in the required certificate store. And if authorization is by certificate - you need both a key and a certificate - yours (which you were given at the CA) - when you authorize, you encrypt the transfer with a key and send only the certificate. The key is a private part - only the owner should have it.
