Build global payments
with Volet.com API

A payment gateway API allows your website or app to process transactions securely and in real time. It acts as a bridge between your frontend and payment processors, enabling seamless checkout experiences while handling data encryption, authentication, and communication with banks or crypto systems.

Payment API integration enables direct communication between your platform and financial infrastructure. This lets you automate billing, payouts, refunds, and transaction monitoring — reducing manual tasks, lowering error rates, and enhancing user satisfaction through faster processing.

When integrating a payment gateway API, developers should focus on documentation clarity, error handling, sandbox testing, multi-currency support, and regulatory compliance. Choosing a gateway with well-structured endpoints and SDKs (like Java libraries) speeds up integration and minimizes bugs.

You can use the payment gateway API to accept crypto payments, automate payouts, manage balances and create custom payment flows. It works for personal projects, SaaS products and large-scale platforms.

Payment API integration is simple: generate your API keys, follow the endpoint documentation and start sending requests from your backend. You can accept payments, trigger payouts and move funds using a clean, modern API.

You can accept and send USDT, USDC, BTC, ETH, TON and other crypto, and manage USD and EUR balances. The API supports conversions, internal transfers and real-time balance checks.

All requests are signed and protected with secure keys. Rate limits, IP controls and real-time monitoring keep integrations safe and reliable.

Some features work without verification, but to use fiat rails, stablecoin payouts or higher limits, a quick KYC/KYB check is required. Verification typically takes just a few minutes.
