Review presence history across channels automatically
Bring channel presence history together for a regular, low effort review.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Query Batch Presence History
This tool enables querying presence history for multiple channels in a single api request. it uses the get endpoint at https://rest.ably.io/presence to retrieve the member presence history details of the specified channels in parallel.
Why this helps
Reconstructing participation across several channels takes repeated lookups and breaks focus.
- Review multiple channels in one scheduled run
- Reduce repeated manual history checks
- Keep participation records easier to scan
Setup
Build it in a few focused steps.
- 1Connect Ably once in the Notis portal.
- 2Create an automation in Automations, or tell Notis the outcome in plain language.
- 3In one instruction, ask Notis to retrieve presence history for the selected channels and summarize the results returned.
- 4Pick the recurring schedule trigger and choose where run reports should go.
- 5Test with one real run and confirm the channels and history interval are appropriate.

Comment Added (Docs/Sheets/Slides)
Triggers when a new comment is added to Google Docs, Sheets, or Slides.
Create Ably Channel
Creates a new channel or retrieves an existing channel in ably. this tool allows you to programmatically create and initialize channels for real-time messaging. since ably creates channels implicitly when first used, this action publishes an empty initialization message to create/activate the channel.
File Created
Triggers when a new file is created in Google Drive.
Delete Channel Subscription
This tool allows you to unsubscribe devices or clients from push notifications for specific channels. the operation is asynchronous, so immediate requests after deletion may briefly still return the subscription.
File Deleted or Trashed
Triggers when a file is moved to trash or permanently deleted in Drive.
Get Channel Details
This tool retrieves metadata and details for a specific channel in ably. it returns a channeldetails object containing information about the channel's status, occupancy, and other metadata. the endpoint provides visibility into channel activity, including metrics such as connections, presence, publishers, and subscribers, and requires appropriate permissions.
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.
Get Channel History
This tool retrieves the message history for a specified ably channel. it uses the get /channels/{channelid}/messages endpoint to return a paginated list of messages in chronological order, subject to parameters such as 'channelid', 'limit', 'direction', 'start', and 'end'. the tool is useful for auditing, recovering missed messages, analyzing channel activity, and debugging message flows. authentication is required via basic or token authentication.
File Updated
Triggers when a file's metadata or content changes in Google Drive.
Get Channel Presence History
This tool retrieves the history of presence messages for a specified channel in ably. it allows you to query presence events on a channel within a given time period.
Google Drive Changes
Triggers when changes are detected in a Google Drive.
Get Ably Service Time
This tool retrieves the current server time from ably's service in milliseconds since the epoch. it is particularly useful for time synchronization and generating valid tokenrequest timestamps to prevent replay attacks. the endpoint supports multiple content types, handles http errors, network issues, and is a fundamental tool for ensuring accurate timing in ably applications.
