Hi Emily,
Pretty much everything that’s non-DM related in the current Activity API (favorites, retweets, follows etc)
Also need the delete equivalent of them, to help us with compliance.
Unfortunately, we have now lost the ability to get this info, it is not possible to get all the data with the REST API (e.g. who favorites, or who retweets more than 100), this was available previously in the Streams API.
It is a twitter guideline not to ask for DM permissions if we are not using DM functions, so we are kind of stuck now and won’t be able to use the new Activity API 
Thanks,
Samir
