Trigger
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Action
Get BART Schedule Arrive
Tool to retrieve schedule information based on a specified arrival time. use when planning trips arriving by a given time.
Why this helps
A changed arrival time can make an old transit lookup unreliable, leaving you to remember to repeat it.
- Use a revised arrival time to request updated schedule information.
- Keep the lookup tied to the itinerary that changed.
- Reduce forgotten schedule refreshes after a plan update.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Bart once in the Notis portal.
- 2Create an automation in Automations, then New Automation, and give it a name.
- 3In one instruction, ask Notis to read the updated itinerary and retrieve BART schedule information for its arrival time and station codes.
- 4Pick the Google Drive File Updated trigger and choose where run reports should go.
- 5Test with one real updated itinerary containing confirmed station codes and an arrival time.

Get GTFS-RT Trip Updates
Tool to fetch real-time trip updates in gtfs-realtime format. use when you need the latest live trip information as raw protobuf.
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
