One API. Every payment method.

CascadX connects to your stack with a single integration. SDK, REST API, webhooks — your choice.

Overview

Build once. Route everywhere.

A single API call sends a transaction into the CascadX engine. The AI picks the PSP, handles the cascade, and returns the result — all through one consistent interface.

Code Examples

Three lines to production.

curlJavaScriptPython
curl -X POST https://api.cascadx.com/v1/charge \
-H "Authorization: Bearer sk_live_..." \
-d amount=4999 -d currency=EUR -d cascade=true
Features

Everything you need to go live.

Webhooks

Real-time event notifications for every transaction state change. Retry-safe with signature verification.

Idempotency

Built-in idempotency keys prevent duplicate charges. Safe to retry any request without side effects.

Sandbox-to-live

Full sandbox environment mirrors production. Flip a key to go live — no code changes.
