I missed to add, we are using REST already in couple of scenarios, but for some scenarios we have challenges building the queries as there are limitations with ODATA queries. One of them is like having filter on Related entity plus
a filter on the primary entity. I couldn't find a way to write a query for this scenario, I may have to write some complex conditions.
So I was thinking to use fetchxml which has more options to build queries. But I am having this issue with that.
