What is the best way to chain APIs on Boomi?
For e.g., I have an API1 defined on Boomi (web-service end-point http://my-atom:9090/ws/rest/API1)
I have a second api, API2, (web-service end-point http://my-atom:9090/ws/rest/API2) which has to call API1 in one of the steps in its process (it has other things to do as well).
What would be the most easy/efficient way to do it? Is the only way to call API1 from API2 through its web-service end-point, even though both APIs are running under the same account on the same atom? Is there a better way of accomplishing this?
