Welcome
One platform for pay-ins, treasury, and pay-outs. Built for the businesses everyone else overcharges or ignores.
MintCash is a payment orchestration platform. You integrate once and we route every transaction through the right provider — picked per merchant, per geography, per card type — to maximize approval rates and minimize fees.
This documentation covers everything you need to go from "zero" to "live in production": the API surface, the concepts behind the state machines, the webhooks you'll receive, and the playbooks for the most common flows.

Quickstart
Make your first test charge in under 5 minutes.
How MintCash works
The orchestration model: routing, cascading, retries.
Concepts
State machines, idempotency, errors, webhooks, and test mode.
Guides
End-to-end walkthroughs for the most common integration tasks — accept a payment, set up subscriptions, issue refunds, go live.
API reference
Every endpoint, every parameter — interactive playground.
What's in the box
- A single REST API for one-time payments, saved cards, and subscriptions
- HMAC-signed webhooks for every state transition so you can react in real time
- Idempotency keys on every charge so retries are safe
- A test mode with reusable card numbers that exercise every success and failure path
- An error taxonomy so failures are easy to branch on
- A Postman collection mirroring every endpoint in the reference
