Make a shared beta roster ready for analysis
When a teammate shares the beta roster, add its listed participants to the cohort for product analysis.
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
Update Amplitude Cohort Membership
Incrementally update cohort membership by adding or removing ids. this action allows you to: - add new ids to an existing cohort - remove ids from an existing cohort - perform multiple operations in a single request
Why this helps
A roster can be ready for the team but still need a separate manual pass before its users appear in the analysis cohort.
- Connect the roster handoff to cohort setup.
- Reduce follow-up work after a roster is shared.
- Keep membership changes focused on listed identifiers.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and Amplitude once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it for shared roster processing.
- 3Tell Notis to use the shared roster's listed user IDs to add participants to the named Amplitude cohort.
- 4Choose File Shared as the trigger and select where run reports should go.
- 5Test with one real share of a roster containing test IDs.
Questions about this workflow
Does sharing itself identify the cohort?
No. The instruction and roster need to make the target cohort clear.
Does this change Drive permissions?
No. The trigger observes new sharing permissions; the action updates Amplitude cohort membership.
