CascadeCheckout is middleware, so every integration is either "call this API on capture" (gateways) or "fire this event on order" (pixels, fulfillment). Full current list below. If your provider is missing, custom HTTP endpoints cover almost anything with a payment intent + capture flow.
Any gateway with an API can join the cascade. First-party wired today:
Full API + 3DS2 + wallets. Route 1 for most low-risk stores.
Including Adyen high-risk desk for merchants past the mainstream threshold.
Customer Vault + 3DS2. Covers every NMI reseller (Fluid Pay, iTransact, Payment Cloud, etc). Details →
High-risk-friendly acquirer. Multi-currency + wallets.
Global-corridor coverage. Strong on APAC + EMEA.
Enterprise-grade rails with real-time reporting.
Europe-focused with iDEAL, SEPA, local rails.
PXP Financial for regulated + high-risk verticals.

Crypto capture as a cascade fallback for card declines.
Pay-by-bank rails for EU + North America.
MENA-region payment gateway with Knet, Mada, wallets.
Any acquirer or PSP that exposes a payment-intent + capture endpoint. Straight banking acquirers, local processors, custom offshore MIDs.

WordPress plugin. Store API for cart, REST API for order writeback. Included on Scale tier, add-on for Growth. Details →

Measurement Protocol integration. Server-side Purchase event fires even when browser pixel is blocked.
Enhanced Conversions via server-side upload with hashed email + phone.
Order-created event fires via Shopify/Woo native integration — cascade preserves the underlying platform event.
Fire your own HTTP webhook on capture, decline, or route rotation.
Cascade writes captured orders back to Shopify or WooCommerce via the standard Admin/REST API. Any tool that hooks the platform's order-created event fires as normal:
We are not the integration platform. We do not replace Zapier or n8n. Cascade's job ends at "write the captured order back to the storefront." From there, your existing storefront-based automations continue.
Any gateway with an API. Currently wired: Stripe, Mollie, Adyen, NMI (and every NMI reseller), Nuvei, Airwallex, Checkout.com, PXP, Whop, Coinbase Commerce, Trustly, MyFatoorah, plus custom HTTP endpoints.

Yes. Full Pixel + CAPI relay for PageView, ViewContent, AddToCart, InitiateCheckout, Purchase events, deduplicated with a shared event_id across browser + server.
Cascade writes captured orders back to Shopify / WooCommerce via the standard Admin/REST API. Any fulfillment app, ERP, subscription tool, or analytics plugin that fires on the platform's order-created event continues to fire normally.
