Keep task details aligned with Slack updates
When a clear update changes the plan, bring the existing task up to date.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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
A task becomes stale after a deadline or scope changes in Slack, leaving planning based on old information.
- Reflect explicit changes in an existing task.
- Keep changed scope or timing visible in planning.
- Reduce manual back-and-forth between a conversation and task list.
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 the matching existing task and update only when a channel message clearly changes its details or due date.
- 3Select Channel Message Received as the trigger and describe how Notis should identify the matching task.
- 4Choose a channel for run reports and test with a real update to a known task.
Questions about this workflow
Does this create a new task when it cannot find a match?
The instruction can ask Notis to update only a clearly matching existing task and otherwise report that no reliable match was found.
What can be updated?
Patch Task can modify provided attributes such as title, notes, due date, or status when the task and list are known.
