title: consume https Rest API with certificate provided
body: <p>I want to consume a https based Rest API, the corresponding team has provided me a zip with certificates, which has two directory with following files  </p>
  
  <pre><code>truststore
   1. desktop-cacerts.jks 
   2. root-ca-g2.crt 
   3. sub-ca-g2.crt
  keystore 
   1. desktop.crt 
   2. desktop.jks 
   3. root-ca-g2.crt 
   4. sub-ca-g2.crt
  </code></pre>
  
  <p>now I want to connect to the service via postman and try out, I tried to add both the jks and .crt files into Postman certificate, but I always get certificate error.
  my understanding is that, I should be using keystore desktop.jks (key file) and desktop.crt to connect, which didn't work; hence I tried other combination but nothing seems to work.</p>
  
  <p>can anyone help me here?</p>
  
  <p><strong>* EDIT *</strong> July 11, 2019 ***
  it turns out the certificate provided had some slight differences, as compare to what the server/RestAPI was expecting, causing it to fail to connect.</p>
  
  <p>Thanks for the help.</p>
