'Changes' API: identifying Merge target Person based on the source Person (rather than vice versa)
I have been analysing some merge history via the output of the Changes API, https://www.familysearch.org/platform/tree/persons/<id>/changes.
I have found that, where there has been a Merge, I can track down the source Person given the target Person, but not vice versa.
On the source Person change history, the change is just shown as 'Person Removed', with no indication that it was caused by a Merge.
The target Person's change history does show a Merge, and gives the source Person ID, but that's not much use if you are starting from the source Person.
Has anyone found a API-based way of automatically identifying the target Person given the source Person?
