Build with ReactionSDK
ReactionSDK powers interactive overlays on videos you control. Use this page as the onboarding hub: get your API key in dashboard, follow the Quick Start docs, then ship with API reference and guides.
Also works on product and hero images (data-reaction-image) for storefronts and funnels—see the image embeds guide, duplicate a starter from the Commerce funnel pack, or jump to Quick Start.
Step 1
Get API key
Open dashboard account settings and use the API Key tab to reveal or copy your key.
Open dashboard account →Step 2
Quick Start
Add script + element, run a test interaction, and confirm events are arriving.
Open Quick Start →Step 3
Integrate by surface
Use platform guides, code examples, and API methods for production rollout.
Open install guides →Stills & PDP
Image overlays
Poll, tap, slider, and rating overlays on product heroes and gallery frames—same SDK and dashboard path as video when you use data-reaction-image.
ReactionSDK and ReactifySDK have different roles
ReactionSDK handles interactive overlays and event analytics on pages you control. ReactifySDK handles user-generated reaction threads, creator workflows, and widgets.
Security notes (current implementation)
- ReactionSDK ingest uses account/device velocity controls and throttling responses.
- Requests are authenticated with API keys and origin checks in the ingest path.
- For infrastructure-level controls, use CDN/WAF rules for additional per-IP protection.
See details in production architecture and security.
