Answer 1

You need a client certificate and a private key from it, as well as a CA certificate.
Next, you need to upload your certificates and configure http.Client.

...
  transport := &http.Transport{TLSClientConfig: tlsConfig}
  client := &http.Client{Transport: transport}

  resp, err := client.Post(...)
...

See the full code here (googled for "golang http request client certificate"):
