***Why is it that we see "source" as "under_armour" when retrieving our users' MapMyFitness fitness records in the Validic API, but using the apps.json API call, we get a different "subname" in the response such as "mapmyfitness"?***

For the MapMy suite of apps, the "subname" in apps.json is not intended to match the “source" field from the Validic API when retrieving fitness records. Since the acquisition of the MapMy apps by Under Armour, all the data for these apps come through the same API and therefore have the source_name when data is retrieved. We have maintained the different apps in the marketplace and apps.json to eliminate confusion when trying to connect to one of the MapMy apps.

When filtering apps.json, use the subname of the desired MapMy app as the value of the source filter in the request.
