I am using airtable with softr for a client portal, and I and trying to configure and automation to send and an email to the portal admin alerting them that a user has logged in for the first time. I have a "users" table in airtable which maps to the "users" table in softr. I have last modified turned "on" in air table. Softr maintains it's own "last seen" field which I have mapped into a matching date field in air table.
The basic logic is that the "last seen" field is empty until a user logs in. So I would think that I would just need to trigger when the "last seen" is part of the "last modified" history? But this alone would result in an email going out every time the last seen field changes which would be every time the user logs in.
I only care about the FIRST time, so I would need a way to check if the "last seen" field was previously empty, then compare it to the current field contents. I just do not understand where I would get the "previous" value from?
I am open to doing this automation within airtable or zapier. Any help would be appreciated.
