Full control over every crypto payment flow your platform needs
The Oppi Payment API gives your team multi-currency crypto payment integration with real-time balance tracking, comprehensive transaction history, flexible withdrawals, and enterprise-grade security throughout.
The building blocks of your crypto payment integration
From dual-layer authentication to real-time balance tracking and flexible withdrawals, every Oppi Payment API feature is designed to give your development team full control at every stage of integration.
One API integration gives your platform access to Bitcoin, Ethereum, and a full range of supported cryptocurrencies. There is no need to manage separate connections or build per-asset integrations for your payment flows.
The Oppi Payment API uses two separate keys to protect every request. Your Auth Key identifies your integration and your Enc Key encrypts the data, so every API call is secured by two independent layers of protection.
The Oppi Payment dashboard lets you generate multiple API keys for different applications or environments. Each key is approved by an admin before activation and can be revoked or replaced at any time to keep your access fully controlled.
Real-time balance updates are delivered automatically to your platform through the API. Every supported cryptocurrency reflects the current accurate balance without any manual input, data polling, or delayed sync from your development team.
You have full control over how withdrawals are processed through the API. Choose manual processing when your team wants direct oversight or use automated withdrawals to move funds efficiently without requiring action each time.
Full transaction records are maintained automatically for every payment your platform processes through the API. Your team has access to detailed, structured payment history at any time without building or managing a separate logging system.
