SVB Virtual Cards API
The Virtual Cards API (v2.0) issues and manages virtual card numbers (VCN) for accounts-payable, procurement, and travel spend. It exposes /v2/card/virtualcards plus authorizations, clearings, real-cards, suppliers, and templates resources, letting partners create single-use or controlled-spend cards and reconcile card activity programmatically.
