Introduction

Stakk is checkout, storefront, and delivery for digital sellers. Connect Stripe, PayPal, or crypto wallets. Buyers pay you directly. We never hold the money.

Start here

• Embed — drop a buy button on any site
• API — create products, list orders, issue refunds
• Theme SDK — build a custom storefront
• Webhooks — get paid and delivered events

Quick embed

<script src="https://your-vinext-host/embed.js"></script>

<button
  data-vinext-product="PRODUCT_ID"
  data-vinext-coupon="SAVE10"
>
  Buy now
</button>

That button opens Stakk checkout in a modal. Coupon, email, quantity, gateway, and custom fields can all be declared as HTML attributes.

REST API

curl https://your-vinext-host/api/dev/v1/products \
  -H "Authorization: Bearer sk_live_..."

Create an API key in Dashboard → Developers. Errors include a doc_url pointing back here.
