I’ve written a blog a while ago on using alternate keys with the Dynamics 365 / CRM WebApi. You can read the blog here. The post guides you in creating an alternate key and identifies some usage scenario’s.
Lately I’ve been working on an integration between Eventbrite and Dynamics 365 / CRM with Microsoft Flow. Currently I’m going back and forth between enthusiasm and disappointment. Sometimes it does more than you would expect and sometimes you’re missing the details you are looking for.
Most often you would want to set a lookup value in a record you are creating and updating. With flow this might be a bit hard as looping is cumbersome, or even impossible, to implement (e.g. nested loops are not supported).
The first thing you could do it set hard coded values. E.g. when creating a product in CRM it’s sometimes feasible to hard code the unit of measure. Simply pasting in the Guids works fine in such case:
Other time you want want to set a lookup to a record you are also integrating. E.g. with Evenbrite you have the ‘entity’ Events that I integrate with a custom entity Events. Event tickets I’m integrating with a custom entity Event tickets. On that event ticket entity I need to set the lookup to the related event. One option would be query for the event in CRM using Flow and setting the value.
However, to simplify things, I’ve created an alternate key on the Event entity in CRM, using the EventId from Eventbrite. Now setting the lookup is fairly easy, and we don’t have to query CRM to fetch the record. This sample works perfectly:
For now, Microsoft Flow seems to be a perfect tool to do lightweight integration scenario’s. Using alternate keys might really help in making your life a little easier in extending the options you have with Microsoft Flow.
