Hey everyone,
We source users from 3 different apps and differentiate user_id. User IDs follow a letter sequence pattern like XVEOP. Recently we noticed that users in the different apps can have the same user_id, causing an issue with identify verification in Intercom. So we decided to implement a new user_id schema for Intercom where we prefix the user_id with the app region (e.g. us-XVEOP, au-WVMNX, etc). This achieves the result where we truly have unique user_ids in Intercom, however it’s resulted in duplicate users being created for every single user…
I’m wondering if anyone has a strategy for the best way to handle deduplicating this while preserving as much of the data as possible. I did come across this community suggestion but I note it’s about 4 years old and I’m wondering if it’s still he best approach. Any ideas on where to start?
