Card Issuing. Crypto Conversion. Real-Time Control. All Through APIs
Vircard is API-first by design. Every function available in the dashboard card creation, spend controls, balance queries, conversion triggers, and reporting is available via the same REST API your development team will integrate with. Build, test in our sandbox, and go live without touching infrastructure you do not own.
API Capabilities
| API Endpoint Group | What You Can Build |
| Card Provisioning API | Create virtual and physical cards for individual cardholders or in bulk. Assign to programs, set initial limits, and activate or freeze instantly. |
| Spend Controls API | Set, update, and remove spend rules programmatically. Define MCC filters, geo restrictions, velocity caps, and approval flows per card or program. |
| Conversion API | Trigger crypto-to-fiat or fiat-to-crypto conversions programmatically. Query live rates, lock rates for a window, and execute conversions against your treasury balance. |
| Balance & Ledger API | Query real-time balances across all currencies and digital assets. Access full transaction history with filtering, pagination, and export. |
| Cardholder API | Create, update, and manage cardholder records. Attach KYC status, link to card programs, and manage lifecycle from onboarding to offboarding. |
| Webhook Events | Receive real-time push notifications for every authorization, settlement, decline, dispute, and status change. Retry logic and delivery guarantees included. |
| Reporting API | Pull structured reports for accounting, reconciliation, and compliance. Choose fields, date ranges, and output formats including JSON and CSV. |
| Partner API | Connect external processors, compliance services, and data tools to your Vircard program. Extend your stack without replacing existing infrastructure. |
