Highlight Chameleon engagement signals with a Slack reaction

Use a Chameleon signal to add a meaningful reaction to its related Slack message, so the team can recognize an adoption milestone or concern at a glance.

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

When product engagement updates get buried in Slack, people can miss which messages need attention.

  • Make a related Slack message easier to spot.
  • Give the team a lightweight signal without creating another message.
  • Use different reactions for meaningful engagement outcomes.

Setup

Build it in a few focused steps.

  • 1Connect Chameleon and Slack once in Notis.
  • 2Create an automation in Notis by naming it and describing the reaction outcome.
  • 3In one instruction, tell Notis which incoming engagement signals should add a reaction and how to identify the related Slack message.
  • 4Choose the Notis webhook trigger and configure Chameleon to send the relevant signal to its webhook URL.
  • 5Choose where run reports go, then test with one real signal and a related Slack message.

Questions about this workflow

Can this workflow find or create a Slack message by itself?

The selected action adds a reaction to an existing Slack message identified by its channel and timestamp. Include enough information to identify that message in the signal or instruction.

Can I use different reactions for different signals?

You can describe the intended behavior in your instruction. The signal and available Slack message details need to support the choice.
