Everything for Terminal Integration
Production-ready features for professional card terminal connectivity
REST API
Control any card terminal through standardized REST endpoints. POST /transactions for a new payment, GET /terminals for device status – as simple as any other API. Complete OpenAPI documentation, SDKs for popular programming languages, and Postman collections for rapid prototyping.
ZVT Protocol Abstraction
Terminal Cloud automatically translates your API calls into the correct ZVT commands. No need to deal with registration sequences, intermediate status messages, or manufacturer-specific TLV containers. The ZVT layer automatically handles connection setup, keep-alive, and protocol handshakes.
Terminal Management
Manage your entire terminal fleet through a central dashboard or the API. Auto-detection, firmware status, connection monitoring, and remote configuration. Organize terminals by location, department, or register and keep track of all devices.
Real-Time Transactions
Start payments, reversals, and refunds via API call. Track transaction status in real time – from card presentation through PIN entry to authorization. Detailed transaction logs with receipt numbers, card type, and authorization codes.
Multi-Terminal Control
Control any number of terminals from a single application. Parallel transactions on different devices, centralized billing and reporting. Ideal for retail chains, restaurants, and events with multiple registers.
Webhooks & Events
Receive real-time notifications about transaction changes, terminal status, and errors. Configure webhooks for specific events or subscribe to the event stream for complete tracking. Retry logic and signature verification for reliable delivery.
