I have a scenario in which I need to integrate data from an external system into Dynamics CRM 2016. I plan to use the new Web API to create and update entities. However, I am wondring if I could update an entity just by specifying the associated Alternate
Key, in case I do not have the GUID ?
I know that It is possible to query an entity by Alternate Key (GET). But is it possible to use Altrrnate Key in PATCH operation ?
