Quick Start

The fastest way to get started is the HTML snippet. For framework-specific guides, see the Widget section.

1. Get your API key

In the Lumifeed dashboard, go to Project Settings → API Keys and create a new key. Copy the key — you'll need it in the next step.

2. Add the snippet

Paste this snippet before the closing </body> tag in your HTML:

<script
  src="https://cdn.lumifeed.app/widget.js"
  data-key="YOUR_API_KEY"
  defer
></script>

Replace YOUR_API_KEY with the key you copied.

3. Open your site

Reload your page. A feedback button will appear in the bottom-right corner. Click it, submit some test feedback, and head to your Lumifeed dashboard to see it arrive.

What's next

• Identify users — attach user ID, name, and email to feedback
• Customize the widget — match your brand colors and position
• Add custom fields — capture structured data alongside feedback
• Set up automations — auto-tag or notify your team on new submissions

Troubleshooting

Widget doesn't appear — Check browser console for errors. Ensure your API key is correct and the project is active.

Feedback not arriving — Check that the API key belongs to the right project. Look at the Network tab for any 4xx responses from api.lumifeed.app.

CORS errors — Lumifeed's API handles CORS automatically for all origins. If you see CORS errors, double-check that your API key is valid and that the src URL is correct.
