I am trying to implement the RMA which triggers web-application.
A particular rule if added/deleted/edited/checked-in via RMA. I should be able to capture the old and new values and pass the trigger back to web-application which will in backend start populating the database for rule execution later in the day.
Is there a simple way to achieve this without using API? If API is the only way through which I can achieve it, then could you provide some possible API's to which I can look at?
