Action

Why this helps
A useful update can get buried in conversation before anyone turns it into a time record.
- Use a quick visual signal to mark work ready for logging.
- Keep the entry tied to the original Slack context.
- Avoid retyping complete work notes into Harvest.
Setup
Build it in a few focused steps.
- 1Connect Slack and Harvest to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis in plain language to log a Slack work note in Harvest when you add your chosen reaction.
- 3In the instruction, say to create an entry only when the message includes the necessary work details and to report anything uncertain.
- 4Pick the Slack message reaction trigger and choose a channel for run reports.
- 5Test by reacting to one real message with a complete project, task, date, and duration.
Questions about this workflow
Can I use a specific emoji to signal a work note is ready?
Yes. Describe the reaction you want Notis to treat as the signal in the plain-language instruction.
Does a reaction provide missing time details?
No. The message still needs enough information for an accurate entry; Notis can report missing details.
