Detecting the user that makes the update

For Pack Sync Tables, does Coda pass an identifier of the user who makes an update to a Coda row?

We’d like to be able to keep track of who is making changes to records. If we can capture the user ID/email to our API endpoint we could log that.

No, unfortunately that information isn’t available. Part of the Packs security model is that they don’t get any implicit access to user data or identity.

Would an opaque ID for the user be valuable for your use case? Or do you need to tie the identifier back to the user in some way?
