Close the loop on completed work
A clear done signal in Slack can update the task you have already been tracking.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Patch Task
Partially updates an existing task (identified by `task id`) within a specific google task list (identified by `tasklist id`), modifying only the provided attributes from `taskinput` (e.g., `title`, `notes`, `due` date, `status`) and requiring both the task and list to exist.
Why this helps
Work is reported finished in Slack, but the corresponding task stays open and clutters the list.
- Keep task status aligned with an explicit completion signal.
- Reduce cleanup after work has already been reported done.
- Make the open task list more trustworthy.
Setup
Build it in a few focused steps.
- 1Connect Slack and Google Tasks once in the portal.
- 2Create an automation with one prompt asking Notis to find and mark the matching existing task complete when your designated reaction is added to a completion message.
- 3Select Message Reaction Added as the trigger and state the completion reaction in the instruction.
- 4Choose where runs should be reported and test against one known completed task.
Questions about this workflow
Will any reaction complete a task?
The prompt should restrict this behavior to your designated completion reaction and a clearly matching task.
What if there is no reliable task match?
Ask Notis to leave tasks unchanged and report that it could not confidently identify the task.

Supported Triggers and Actions
Notis builds workflows that link Slack to Google Tasks. A trigger fires from one place; an action lands in another.
Slack triggers
Google Tasks actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Clear tasks
Permanently clears all completed tasks from a specified google tasks list; this action is destructive and idempotent.

Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Delete task list
Permanently deletes an existing google task list, identified by `tasklist id`, along with all its tasks; this operation is irreversible.

Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Insert Task
Creates a new task in a given `tasklist id`, optionally as a subtask of an existing `task parent` or positioned after an existing `task previous` sibling, where both `task parent` and `task previous` must belong to the same `tasklist id` if specified.

DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
