Notis

Mark booking reviews with a Slack reaction

Give the team a lightweight visual signal after a booking has been checked against the criteria you provide.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Add reaction to message

Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.

Why this helps

Review status can stay unclear when someone checks a booking but forgets to signal that the team can move on.

  • Make a completed check visible at a glance.
  • Use a reaction as a lightweight team signal.
  • Tie the review condition to criteria you provide.

Setup

Build it in a few focused steps.

  • 1Connect Appointo and Slack once in the Notis portal.
  • 2Create an automation in Automations, or tell Notis in plain language from any channel.
  • 3Ask Notis to check the booking and add a specified reaction to the Slack message identified in the request only when the supplied review condition is met.
  • 4Choose the webhook trigger and a channel for run reports.
  • 5Test with one real booking and message, then confirm the reaction is appropriate.

Questions about this workflow

Does Notis choose the Slack message automatically?

The webhook request or instruction must identify the existing message and its channel. The action needs a message timestamp.

Can the reaction mean a booking is approved?

Use a reaction only for a meaning your team has agreed on, and define the condition in the instruction. Notis should not infer approval criteria.
