Hi @EllaClark, 

Yes, you can automate tagging of Databricks notebooks based on folder structure using the REST API and a script. Use the Workspace API to list notebook paths, extract folder names, and treat them as tags.

If the API supports metadata updates in your environment, you can apply tags directly. Otherwise, maintain a separate path to tag mapping. You can also schedule this as a Databricks Job to keep tags up to date as your workspace changes.
