title: How to update Postman collections when new requests get updated by developer to the api
body: <p>I have my API's document in Swagger which have different endpoints or request.
  I used the <code>swagger.json</code> link from my API's in Swagger to import them to Postman as collections and then add test cases there.</p>
  
  <p>But I am confused on one thing that if the developers add more requests to the API how can I import the new request without impacting the test cases.</p>
  
  <p>For e.g.:<br>
  In one case I have one API with 65 requests that I imported from Swagger UI and test cases written.
  Then after few days I used the same link to import and number of requests changed to 69 which means 4 new request got added but Postman replaced the whole collection with test cases gone.</p>
