Confirm Resource Bookings with a Slack Reaction
A clear approval reaction can be enough to move an agreed resource plan into Hub Planner, with less chasing and fewer copy-paste steps.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Create Booking
Tool to create a new booking for a resource on a project in Hub Planner. Supports scheduled bookings, booking requests (WAITING_FOR_APPROVAL), and hourly bookings. Use when you need to allocate resources to projects with specific start/end dates and time commitments.
Why this helps
Approved allocations can stay stuck in chat because updating the planning system becomes one more follow-up task.
- Use an explicit team signal to capture agreed allocations.
- Reduce follow-up between approval and resource planning.
- Keep tentative proposals from being treated as confirmed bookings.
Setup
Build it in a few focused steps.
- 1Connect Slack and Hub Planner to Notis once through the portal.
- 2Create an automation that tells Notis to create a booking only when the designated approval reaction confirms a complete proposal.
- 3Select the Slack message reaction added trigger and choose a run-report channel.
- 4Test with one real approved proposal that includes clear resource, project, and dates.
Questions about this workflow
Will any reaction create a booking?
Specify the exact approval reaction and require a complete, clearly approved proposal.
What should happen for incomplete proposals?
