Add crypto checkout to your store
Every integration follows the same shape: your store creates a payment through the Merchant API, the buyer pays on the hosted checkout, and a signed webhook advances the order. The settlement stays non-custodial the whole way through: funds land in wallets you control. The fee is 0.5% per confirmed payment on every integration.
This page lists plugins that are shipped and installable today. We do not publish placeholder pages for platforms we have not built yet.
WooCommerce
A redirect-to-hosted-checkout gateway for WordPress. Coin groups become their own payment methods, orders advance on signed webhooks, and both the classic and block checkouts are supported.
Install guideOpenCart
Separate builds for OpenCart 3.0.x and 4.0.x with the same flow: hosted checkout, signed webhooks, order-status mapping, and coin groups as their own payment options.
Install guideWHMCS
A gateway for the WHMCS billing and hosting platform. Clients pay an invoice on the hosted checkout, a re-verified signed webhook marks it paid, and funds land in your own wallet. Self-hosted WHMCS 8.13 and 9.0.
Install guideEverything else: the API
Custom carts, SaaS billing, and invoicing run on the same Merchant API the plugins use: create a payment, redirect to the hosted checkout, consume the signed webhook. The API reference covers the whole surface.

- Do the plugins support test mode?
- Yes, and it is the recommended path: an API key with the pk_test_ prefix runs the same plugin against testnets, using the test credit every account starts with. You place a real order, watch the webhook advance it, and then swap in a pk_live_ key with no other configuration change.
- Can one store offer several crypto payment options?
- The WooCommerce and OpenCart plugins support coin groups: you name a set of coins, such as Stablecoins or Bitcoin, and each enabled group appears at checkout as its own payment method with an optional logo and default coin. WHMCS binds one payment method per module, so instead of separate methods it takes an accepted-coins list you can either hold buyers to or use only to pre-select the opening coin. Either way you control which coins a buyer sees.
- What if my platform has no plugin yet?
- Integrate the Merchant API directly: one server-side call creates the payment and returns the hosted checkout URL, and one webhook consumer advances your order when the payment confirms. The shipped plugins are thin wrappers around exactly this flow, so the API path is equally supported.
