Squarespace
If your current plan permits scripts in Code Blocks, add the snippet and test the published page.
Integrations
Embed a free Stripe donation form on sites that permit script-based custom HTML.
A generated two-line snippet adds a branded, Stripe-powered donation form to the website you already have. No backend, no platform fees — donations go straight to your own Stripe account. On WordPress, there’s a free plugin too.
The embed
Two lines of HTML. That’s the whole install.
Your dashboard generates this snippet with your organization and form filled in. Add it where your platform and current plan permit script-based custom HTML.
<div data-kindlumen-inline="https://www.kindlumen.com/give/your-org/forms/donate"></div>
<script async src="https://www.kindlumen.com/embed/widget.js"></script>Prefer a button? Swap in the popup snippet, a floating Donate button that stays in view on every page, or link to your hosted donation page — every form ships with all of them.
Platforms
Works where you build.

FAQ
Embed questions, answered.
Do I need a plugin to embed the donation form?
No. The embed is a div and an async script tag. It works where a site builder and its current plan permit script-based custom HTML. On WordPress you can instead install KindLumen – Free Stripe Donation Forms for a guided account connection, shortcodes, a block, and campaign displays.
How does the embed work technically?
The snippet renders a KindLumen form in an iframe. On the Stripe route, the inline flow uses Stripe Checkout Elements when available and can fall back to hosted Stripe Checkout. Payment details are not submitted to or stored by the website carrying the embed.
Will the embed slow my website down?
The widget script loads asynchronously and the form renders in an iframe, which keeps the integration separate from your page code. It still adds network and rendering work, so measure the published page with your site’s theme, consent tools, and other scripts enabled.
What if my page builder doesn’t allow custom scripts?
Every form also gets a hosted donation page on KindLumen. Link to it from an existing button, menu, email, or social post when your website cannot run the embed script.
Is it free to use on client websites?
Yes. Agencies and developers embed KindLumen’s free Stripe donation form on client sites with no platform fees. Each organization connects its own Stripe account, so client funds never route through you or KindLumen.
