Instapage

Instapage is strict about script security—host the SDK on an allowed domain and follow their external script guidelines. Always publish to a live URL to test.

Where to paste code

Settings → JavaScripts (global or page-level).
HTML widgets embedded in the page.

Setup guide

Add external script URL to Instapage-approved configuration.
Initialize after load; include each published hostname in allowedOrigins.
Embed custom elements; duplicate-check when cloning pages across workspaces.

Example snippet

ReactionSDK here means overlays on reaction-video (tap, poll, rating, slider, and CTA). For ReactifySDK—recorded video reactions and threads—load reactify.js and use reactify-video / reactify-thread per ReactifySDK HTML install. Copy the embed from the Code column.

Verification

Publish to a live URL; open in a clean session and confirm the SDK loads without CSP errors.
Trigger first render and first interaction; check ReactionSaaS analytics.
Use the SDK playground with Instapage selected to mirror overlay settings.

Template `platform_config`

Marketplace templates can declare a Instapage block inside platform_config:

UI presets (reference)

Fullscreen / CTA — Single primary conversion path; respects reduced motion. Events: install_completed, first_render, first_interaction, template_used, platform_used, verification_heartbeat.
Inline conversion block — Lazy-load; threads reactions to the same campaign as the page. Events: first_render, first_interaction, install_handoff_started, install_handoff_completed.
Lead-gen overlay — Does not block native form submit. Events: first_render, first_interaction, template_used.

Troubleshooting

Script does not run — Use a raw HTML or global script area; rich-text-only fields often strip JavaScript.
403 from API — Add the exact published origin (including www) to allowed domains.
Duplicate events — Ensure only one SDK init per page when combining global and section-level code.

FAQ

Script rejected? Use Instapage’s script manager UI rather than inline paste where blocked; contact their support for CSP allowlists.

Code

ReactionSDK (sdk.js)

<script src="https://reactify-cdn.s3.us-east-2.amazonaws.com/sdk.js" defer></script>
<script>
  window.addEventListener('DOMContentLoaded', function () {
    var sdk = window.reactionSDK || window.Reactify;
    if (!sdk || !sdk.init) return;
    sdk.init({
      apiKey: 'YOUR_API_KEY',
      baseUrl: 'https://YOUR_APP_ORIGIN',
      mode: 'production',
      allowedOrigins: [window.location.origin]
    });
  });
</script>
<reaction-video
  src="https://cdn.example.com/demo.mp4"
  overlays="tap,poll,rating,slider,cta"
  interaction-type="tap"
  cta-text="Continue"
  poll-question="Ready for the next step?"
></reaction-video>

ReactifySDK expansion (optional)

<script src="https://reactify-cdn.s3.us-east-2.amazonaws.com/reactify.js" defer></script>
<!-- After overlays are live, load reactify.js for recorded video reactions: reactify-video, reactify-thread, and thread embeds. -->

<script src="https://reactify-cdn.s3.us-east-2.amazonaws.com/sdk.js" defer></script>
<script>
  window.addEventListener('DOMContentLoaded', function () {
    if (!window.Reactify) return;
    Reactify.init({
