Introduction
Welcome to the Flash Protocol Payment Gateway API.
Overview
The Payment Gateway API allows you to programmatically create payment links, manage transactions, and integrate crypto payments directly into your application. We designed our API to be simple, RESTful, and secure.
Whether you are building an e-commerce platform, a subscription service, or a specialized dApp, our API provides the tools you need to accept cross-chain payments effortlessly.
Key Features
- Universal Acceptance: Accept payments from Ethereum, Arbitrum, Polygon, Optimism, Base, and more.
- Automatic Bridging: We handle the cross-chain complexity. You just receive your preferred token (e.g., USDC).
- Instant Settlement: Funds are routed directly to your wallet in real-time.
- Developer First: Webhooks, typed responses, and predictable error codes.
