Mark contact updates where the team already talks
Keep a useful contact update attached to the Slack conversation it belongs with. A webhook can prompt Notis to react to a specific message when it has the required details.
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
A useful CRM update can be easy to miss when the team has already discussed the relationship in Slack.
- Make a relevant existing Slack message easier to notice
- Keep follow-up attached to the conversation
- Avoid reposting an update when a reaction is enough
Setup
Build it in a few focused steps.
- 1Connect Attio and Slack once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, tell Notis when to react and which emoji to use for the specified Slack message.
- 4Pick the webhook trigger and choose where run reports should go.
- 5Test with one real example that includes the Slack channel, message timestamp, and contact context.
Questions about this workflow
What details are needed to add a reaction?
The action requires the Slack channel and timestamp for an existing message, plus the emoji to add. Include those details with the webhook or make them available to Notis.
Does this action send a Slack message?
No. It adds a reaction to an existing message and does not create a new message.
What if the Attio update does not identify a Slack message?
Notis cannot identify a target message from the contact update alone. Supply the channel and timestamp or use a workflow whose action does not require a specific message.
