Get BART station details when a trip folder is shared
Share the travel folder and let Notis pull station details for the code included in its trip materials.
Trigger
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.
Action
Get Station Info
Tool to fetch detailed information for a specified bart station. use after you have a station's abbreviation. (e.g., get station info for 'balb')
Why this helps
When a trip plan is shared, recipients may still need to look up station information in another place.
- Make station details easier to find after a trip folder is shared.
- Use the station abbreviation provided in trip materials.
- Reduce follow-up searches for station information.
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 identify the BART station abbreviation in the shared trip material and retrieve its station information.
- 4Pick the Google Drive File Shared trigger and choose where run reports should go.
- 5Test by sharing a real trip file or folder that includes a confirmed station abbreviation.
Questions about this workflow
What if the shared material has no station code?
The Bart station information action needs a station abbreviation. Add the abbreviation to the trip material for a grounded lookup.
Does every shared file trigger a useful lookup?
The automation runs on the listed Drive sharing event. Its instruction should focus on shared travel material that identifies a BART station.
