Update Canvas assignments after canceled Google events
Reflect schedule changes in Canvas before learners act on outdated details.
Trigger
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.
Action
Edit assignment
Updates an existing assignment in a canvas course (identified by `course id` and `assignment id`); only attributes explicitly provided in the request are modified.
Why this helps
Canceled sessions leave assignments with stale dates and instructions.
- Keeps assignment instructions aligned with schedule changes
- Reduces student confusion
- Creates a consistent response to cancellations
Setup
Build it in a few focused steps.
- 1Connect Google Super and Canvas in Notis once.
- 2Create an automation named Canceled session assignment update.
- 3Tell Notis to find the related Canvas assignment and update its instructions or dates based on the cancellation details.
- 4Pick Event Canceled or Deleted as the trigger, choose a report channel, and test with one canceled event.
Questions about this workflow
How does Notis identify the assignment?
Provide matching course or naming context in the instruction, or ask Notis to report ambiguous matches.
Can it delete the assignment?
Only ask for deletion when that outcome is intentional and the assignment is unambiguously identified.

Supported Triggers and Actions
Notis builds workflows that link Google Super to Canvas. A trigger fires from one place; an action lands in another.
Google Super triggers
Canvas actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Create account notification
Creates a global notification within a canvas account, ensuring `end at` is after `start at` and any specified `notification roles` are valid.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create appointment group
Creates a new appointment group in canvas for schedulable time slots within specified course or group contexts.
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
Create an assignment
Creates a new assignment within a specified course in canvas lms.
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
Create assignment override
Creates an assignment override to adjust due/unlock/lock dates for an assignment in a course, targeting specific students (requires `title`), a group, or a course section; at least one target (`student ids`, `group id`, or `course section id`) is required.
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
Create Calendar Event
Creates a calendar event with options for recurrence (finite `rrule` series only), section-specific timings, and blackout dates within a specified context.
Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Create communication channel
Creates a new communication channel (e.g., email, sms, push) for an existing canvas user to receive notifications.
Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
Create content share
Shares a canvas content item to specified users, if the sender has necessary permissions and receiver ids are valid.
Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
Create conversation
Use to send messages in canvas by creating a new conversation or adding to an existing one; an existing conversation with the same recipients (and matching scope/filter, if specified) may be reused unless `force new` is true.
