Close the Loop When a Meeting Is Canceled
A cancellation can prompt a quick cleanup step in the app where the related work lives.
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
Execute Composio Tool
Execute a tool using the composio api.
Why this helps
Canceled meetings can leave reminders or related work hanging around unless someone remembers to clean them up.
- React to canceled or deleted calendar events.
- Use the event ID and available summary to locate relevant follow-up tools.
- Reduce manual cleanup after a meeting is called off.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Composio once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis what to do from any channel.
- 3In one instruction, describe the cleanup outcome and tell Notis to search Composio for and execute a suitable available tool.
- 4Pick Event Canceled or Deleted as the trigger and choose where run reports should go.
- 5Test with one real canceled event and review the action result.
Questions about this workflow
What cancellation details are available?
The trigger returns a minimal payload with event ID, summary when available, and cancellation timestamp.
Can this find and clean up every related item?
Only if the relevant Composio tool is available, connected, and can locate the related item from the information provided. The instruction should specify the intended cleanup.

Supported Triggers and Actions
Notis builds workflows that link Google Calendar to Composio. A trigger fires from one place; an action lands in another.
Google Calendar triggers
Composio actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Ask Oracle
Static helper that returns a comprehensive system prompt describing how to plan and execute tasks using the available composio tools and workflows. no inputs required; simply call to retrieve the prompt. always call this after the search tool is executed -- it will provide the best context on how to proceed, chain tools, and execute the task end-to-end. relevant tools referenced by the prompt: 1. composio search tools 2. composio multi execute tool 3. composio execute code 4. composio manage connections 5. composio bash tool
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Check active connection (deprecated)
Deprecated: use check active connections instead for bulk operations. check active connection status for a toolkit or specific connected account id. returns connection details if active, or required parameters for establishing connection if none exists. active connections enable agent actions on the toolkit.
Attendee Response Changed
Polling trigger that fires when any attendee's RSVP changes to accepted, declined, or tentative. Returns attendee info and current status.
Check multiple active connections
Check active connection status for multiple toolkits or specific connected account ids. returns connection details if active, or required parameters for establishing connection if none exists. active connections enable agent actions on toolkits.
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.
Create Plan
This is a workflow builder that ensures the LLM produces a complete, step-by-step plan for any use case. WHEN TO CALL: - Call this tool based on COMPOSIO_SEARCH_TOOLS output. If search tools response indicates create_plan should be called and the usecase is not easy, call it. - Use this tool after COMPOSIO_SEARCH_TOOLS or COMPOSIO_MANAGE_CONNECTIONS to generate an execution plan for the user's use case. - USE for medium or hard tasks — skip it for easy ones. - If the user switches to a new use case in the same chat and COMPOSIO_SEARCH_TOOLS again instructs you to call the planner, you MUST call this tool again for that new use case. Memory Integration: - You can choose to add the memory received from the search tool into the known_fields parameter of the plan function to enhance planning with discovered relationships and information. Outputs a complete plan with sections such as "workflow_steps", "complexity_assessment", "decision_matrix", "failure_handling" "output_format", and more as needed. If you skip this step for non-easy tasks, workflows will likely be incomplete, or fail during execution for complex tasks. Calling it guarantees reliable, accurate, and end-to-end workflows aligned with the available tools and connections.
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.
Enable trigger
Enable a specific trigger for the authenticated user.
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).
Execute agent
Execute complex workflows using ai agent reasoning between multiple tool calls. use this for: complex multi-step workflows requiring reasoning, error handling and retry logic. use composio multi execute tool instead for: simple parallel operations, batch operations on similar data (e.g., fetch 5 emails, get 10 sent messages, retrieve multiple user profiles), independent tool calls that don't need each other's results, or bulk operations where all parameters are known upfront. performance: agent calls add ~2-3 seconds overhead. use for workflows >3 tools or requiring conditional logic. avoid for simple parameter passing.
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
Execute Composio Tool
Execute a tool using the composio api.
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).
Get Tool Dependency Graph
Get the dependency graph for a given tool, showing related parent tools that might be useful. this action calls the composio labs dependency graph api to retrieve tools that are commonly used together with or before the specified tool. this helps discover related tools and understand common workflows.
