Notis builds workflows that link Google Tasks to Ably. A trigger fires from one place; an action lands in another.
Google Tasks triggers
Ably actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Query Batch Presence

Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
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.
New Task Created
Triggers when a new task is created in a Google Tasks list. Uses timestamp filtering (updatedMin) to efficiently detect new tasks.
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.
New Task List Created
Triggers when a new Google Tasks task list is created. This trigger monitors Google Tasks and fires when new task lists are detected.
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.

Triggers when a specific task's details change. This trigger monitors a single Google Task and fires when any of its details (title, notes, status, due date, completion, position) are modified.
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.
Task List Changed
Triggers when a task list changes (title or content updates). This trigger monitors a specific Google Tasks list and fires when changes are detected.
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.

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.
