I’m not sure about an option to do this with logging into the base, but if it helps, On2Air has a Field Difference Log function where you can keep a log of changes to a single field or multiple fields.
It will keep a running log of changes to any field and each change is stored in a long text field with a timestamp and some other options.
You can read a little more about it - Field Difference Log
Thank Hannah. Airtable itself tracks field-level changes pretty nicely, but that’s not what I was asking about. I want a base access log, that is, a record of how often the base is accessed and by whom. Apparently NOT possible, which is a bummer. I’m pretty sure that front-end builders like Softr, Miniextensions and Stacker do make this possible. I was just trying to see what can be done in Airtable alone.
