title: Best Practice : Roundtrip calls in Restful Event driven Microservice Architecture
body: <p>I am using an Event Driven Microservice architecture with Rest Endpoints.</p>
  <p>I am looking for advice on microservice roundtrip calls.</p>
  <p>For eg, in my app I have Services &quot;A&quot; and &quot;B&quot;.</p>
  <p>Service B calls A's post method, and &quot;A&quot; again calls a get method on &quot;B&quot; to get some data to prepare the final result. I am using this approach to break cyclic dependency.</p>
  <p>Almost all articles i have read so far talk about 'reducing' round trips and not necessarily 'eliminating' them.</p>
  <p>What does microservice best practice say about such roundtrips ?</p>
