Connect HubSpot in the ReactionSaaS dashboard and install ReactionSDK on HubSpot-managed pages using a server-hosted loader tag. Your API key stays on ReactionSaaS servers — the loader calls Reactify.init() when the page loads.
1) Connect HubSpot
In the ReactionSaaS dashboard, go to Integrations → HubSpot and click "Connect HubSpot" to authorize. Then enter your campaign and creative IDs and save install settings.
2) Install loader on a HubSpot page
After saving settings in the dashboard, copy the loader tag and paste it into a HubSpot Custom HTML module. You can also use a minimal URL with only ?account=YOUR_ACCOUNT_ID if full settings are saved in the dashboard.
<!-- ReactionSDK for HubSpot (server-hosted loader) -->
<!-- Replace YOUR_ACCOUNT_ID, YOUR_CAMPAIGN_ID, YOUR_CREATIVE_ID with dashboard values -->
<script src="https://www.reactionsaas.com/integrations/hubspot/reaction-sdk-loader.js?account=YOUR_ACCOUNT_ID&campaign=YOUR_CAMPAIGN_ID&creative=YOUR_CREATIVE_ID"></script>3) Verify
Publish your HubSpot page, load it in a browser, and interact with a ReactionSDK overlay. The dashboard Integrations panel detects loader beacons and first events automatically.
