Block a user from your GitHub org when an offboarding event is created
Offboarding is where access loose ends hide, and a lingering account is a real risk. When an offboarding event is booked on your calendar, Notis blocks the departing user from your GitHub organization, so their access is closed off exactly when it should be.
Trigger
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
Action
Block a user from an organization
Blocks an existing github user from an existing organization, preventing their contributions, collaboration, and forking of the organization's repositories.
Why this helps
Departing people keep organization access longer than they should, because revoking it is a manual step that gets lost in the shuffle of offboarding.
- Access is cut off at the scheduled offboarding, not weeks later.
- Closes a real security gap without relying on memory.
- Ties a sensitive step to a concrete calendar event.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and GitHub to Notis once in the portal.
- 2Tell Notis: When an offboarding event is created, block the departing user from our GitHub organization.
- 3Select the Google Calendar event created trigger.
- 4Choose a channel where Notis confirms the block.
- 5Test with a sample offboarding event and verify the outcome.
Questions about this workflow
What does blocking do?
It prevents the user from contributing to, collaborating on, or forking the organization's repositories.
Can I unblock later?
Yes. Ask Notis to unblock the user if the situation changes.
Does it work on any account?
It blocks an existing individual GitHub user, not an organization or your own account.

Supported Triggers and Actions
Notis builds workflows that link Google Calendar to GitHub. A trigger fires from one place; an action lands in another.
Google Calendar triggers
GitHub actions
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
Accept a repository invitation
Accepts a pending repository invitation that has been issued to the authenticated user.
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
List repositories starred by the authenticated user
Deprecated: lists repositories starred by the authenticated user, including star creation timestamps; use 'list repositories starred by the authenticated user' instead.
Event Starting Soon
Triggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available.
List stargazers
Deprecated: lists users who have starred a repository; use `list stargazers` instead.
Calendar Event Changes
**SOON TO BE DEPRECATED** - Use Calendar Event Sync (polling trigger) instead. Real-time webhook trigger for calendar event changes. Returns event metadata only. For full event data, use Calendar Event Sync (polling trigger).
Star a repository for the authenticated user
Deprecated: stars a repository for the authenticated user; use `star a repository for the authenticated user` instead.
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
Add email for auth user
Adds one or more email addresses (which will be initially unverified) to the authenticated user's github account; use this to associate new emails, noting an email verified for another account will error, while an existing email for the current user is accepted.
Calendar Event Sync
Polling trigger that returns full event data including details, attendees, and metadata. For real-time notifications with basic info, use Calendar Event Changes (webhook).
Add app access restrictions
Replaces github app access restrictions for an existing protected branch; requires a json array of app slugs in the request body, where apps must be installed and have 'contents' write permissions.
Event Updated
Triggers when an existing Google Calendar event is modified. Returns the event ID, change type, and the specific fields that changed with their previous and new values.
Add a repository collaborator
Adds a github user as a repository collaborator, or updates their permission if already a collaborator; `permission` applies to organization-owned repositories (personal ones default to 'push' and ignore this field), and an invitation may be created or permissions updated directly.
Add a repository to an app installation
Adds a repository to a github app installation, granting the app access; requires authenticated user to have admin rights for the repository and access to the installation.
