Send a Slack alert when a HubSpot deal changes stage using Make

Prerequisites

Make account (Free plan works for this scenario)
HubSpot connection configured in Make via OAuth
Slack connection configured in Make

Step 1: Add a Watch Deals trigger

Create a new scenario. Add a HubSpot CRM → Watch Deals module:

Connection: Your HubSpot OAuth connection
Watch: Updated deals
Limit: 10 (per poll cycle)

This module fires whenever a deal is updated. It returns the full deal record including all properties.

Step 2: Add a filter for stage changes

Click the line between the Watch Deals module and the next module to add a Filter:

Condition: dealstage → Not equal to → {{previous.dealstage}}

This ensures you only process deals where the stage actually changed, not every minor property update.

Alternative: use the property change filter

If your Make plan supports it, you can filter directly in the Watch Deals module for the dealstage property change, which is more efficient than filtering after the fact.

Step 3: Resolve stage name

Add an HTTP module to fetch pipeline stages:

URL: https://api.hubapi.com/crm/v3/pipelines/deals
Method: GET
Headers: Use the HubSpot connection for auth

Then add a Set Variable module or use Make's built-in map() function to look up the stage label from the pipeline response.

Step 4: Send Slack message

Add a Slack → Create a Message module:

Connection: Your Slack connection
Channel: Select #sales-pipeline
Text:

🔄 *Deal Stage Changed*
*{{dealname}}* moved to *{{stageName}}*
Amount: ${{formatNumber(amount; 0; "."; ",")}}

For richer formatting, use the Blocks field with Block Kit JSON.

Step 5: Schedule and activate

Set the scenario schedule to Immediately (processes as soon as HubSpot emits the event)
Toggle the scenario to Active
