What alternative is there to the HubSpot webhook?

Since you don’t have access to HubSpot’s webhook subscription, you can use HubSpot Workflows with Custom Code actions to trigger external API calls when a deal moves to “qualifiedtobuy.” Alternatively, you can poll the HubSpot API at intervals to check for stage changes or use private app webhooks for specific property updates. Third-party tools like Zapier, Make, or n8n can also automate triggers efficiently without causing infinite loops. If you need a real-time solution, the Workflows + Custom Code method is the best alternative.
