Payments - Kleap Documentation

You can accept payments on your Kleap site using Stripe. Because Kleap sites are fast, mostly-static websites, the simplest and safest way to sell is with Stripe Payment Links and Buy Buttons — no server or secret keys required.

Stripe Payment Links and Buy Buttons are hosted by Stripe and embed with a public key only. That means no sensitive keys ever live in your site’s code — which is safer and works perfectly with a static site.

The Easy Way: Payment Links

A Payment Link is a Stripe-hosted checkout page you can link to from any button.

Create products in Stripe

In your Stripe Dashboard, create a product and price (one-time or subscription).

Create a Payment Link

Go to Payment Links → New, pick your product, and copy the link (looks like https://buy.stripe.com/...).

Add it to your site

Ask the AI to add a buy button:

Add a "Buy now" button in the pricing section that links to
https://buy.stripe.com/your-link-here

That’s it — clicks go to Stripe’s secure checkout, and Stripe handles payment, receipts, and (for subscriptions) recurring billing.

Buy Buttons & Pricing Tables

Stripe also offers embeddable Buy Buttons and Pricing Tables you can drop into a page. Create one in Stripe, then:

Embed this Stripe pricing table on my Pricing page:
<stripe-pricing-table pricing-table-id="..." publishable-key="pk_live_...">
</stripe-pricing-table>

Only ever use your publishable key (pk_live_... / pk_test_...) in your site. Never put a secret key (sk_...) in a website — it must stay private.

Test vs Live Mode

Mode	Keys / Links	Use
Test	Test-mode payment links, `pk_test_`	Try the flow safely
Live	Live payment links, `pk_live_`	Real payments

Test Card Numbers

Use these in test mode:

Card Number	Result
`4242 4242 4242 4242`	Success
`4000 0000 0000 0002`	Declined
`4000 0000 0000 3220`	Requires 3D Secure

Advanced: Custom Checkout

Fully custom, server-side Stripe flows (dynamic carts, metered billing, custom webhooks) require a backend to hold your secret key. That’s beyond a static site — if you need it, you’d pair your site with your own backend or a serverless function. For most sites, Payment Links and Buy Buttons cover selling products, plans, and services.

Best Practices

Use Payment Links for most cases

They’re the fastest, safest way to sell on a static site — no keys in your code.

Keep secret keys out of your site

Only publishable keys belong in a website. Secret keys stay in Stripe / a backend.

Test before going live

Run a test-mode purchase end to end before switching to live links.

Troubleshooting

Button doesn't open checkout

Make sure the button links to a valid https://buy.stripe.com/... Payment Link, and that the link is set to live mode when you’re ready for real payments.

Pricing table not showing

Confirm you used your publishable key (pk_...) and the correct pricing-table ID from Stripe.
