Dear Maxim, For some of my online apps, I have well defined databases of users with their specific IDs. So, when I connect them to OM via REST, I assign a modified version of their IDs to the 'externalId' parameter. That creates a new record for the given user in the OM database. Subsequently, when the same user connects, no new copies of the same user are created. This is very good.
But in one app, I have the ability for guests to connect, who are not members of my app. In that case, I initially was creating random 'externalId' values for them. I noticed that this causes OM to create a new record in the OM database each time the same individual connects. So, I had many copies of the same person created, cluttering my database. Not so good. A solution I found is that for each non-member guest, I assign the same value to the 'externalId', e.g. 'externalId': 'guest'. This seems to be working well, and it does NOT clone the same poor individual a multitude of times. I just wanted to confirm with you that this would be an alright solution and would not cause any conflicts or crashes (i.e., assigning the same externalId for unregistered guest users). Thank you!
