title: How to composite multiple API call in API gateway?
body: <p>I am looking in to how to use API gateway in my project. My current API gateway pattern idea is to create a layer of composite APIs calling multiple APIs, and expose the composite APIs through the API gateway.</p>
  
  <p>Researching elsewhere, I've found that it is not recommended to create composite APIs if using an API gateway, but rather that composition should happen in the API gateway itself. But if I need to do the composition in API gateway, doesn't that mean that I need to expose some domain logic there, because would I need to construct a meaningful request contract and possibly a sequence of calling APIs? Personally, I don't feel comfortable doing that.</p>
  
  <p>Is there other way to do this without exposing some logic?</p>
