Mark verified contacts in Slack

Make completed checks visible on the conversation your team already uses to review a contact.

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

Verification status can be hard to spot when it lives separately from the Slack discussion about a lead.

  • Show that a check passed without adding another status update.
  • Keep the verification signal attached to an existing Slack message.
  • Help teammates scan active discussions faster.

Setup

Build it in a few focused steps.

  • 1Connect Abstract and Slack once in the Notis portal.
  • 2Create an automation in Automations, New Automation, and name it.
  • 3In one instruction, ask Notis to add your chosen reaction to the Slack message identified in the webhook only when the Abstract result meets your verification criteria.
  • 4Choose the webhook trigger and where run reports should go.
  • 5Test with a real result and the Slack message timestamp it belongs to.

Questions about this workflow

What does the webhook need to include?

Include the Abstract result and the Slack channel and message timestamp for the message to react to.

Does the reaction replace the original message?
