The card identifier returned during card creation or listing.

Request Body

The reviewed public contract accepts a flexible JSON payload here. In practice, a safe funding request should include:
  • amount_minor
  • currency
  • transaction_reference
  • idempotency_key
Legacy reference may still be accepted by some downstream services, but new integrations should prefer transaction_reference.

Example Request

Response Notes

  • The reviewed public OpenAPI models this as an accepted async-style operation.
  • Use stable business references and idempotency keys for retries and reconciliation.
