Finding the API User ID for a given user

Hi everyone,

I’ve been trying to work out how I might find the API User ID for a user. I’ve tried hunting through the docs and the community here, but I suspect I’m searching using the wrong terms - what I’m trying to do is track down the API User ID from the user’s email address.

The Edit User interface shows me the legacy UUID for the user, but not the API User ID.

Does anyone have any insights? TIA!
