I noticed that New Person activities when a new record is created via REST API now have these detail fields:
'modifying user', 'api method name', and 'request id' all make troubleshooting problems much easier.
But please also make the "modifying user" field a constraint on Person Is Created trigger and Person Was Created filter. I dealt with a vendor recently who was under the mistaken assumption that we would be able to run automation based on the modifying user - and it would be nice if we could!
Thanks again for the upgrade!
