​
🚀 Added

  • Receipts management: Two resource operations were introduced for payment receipt management:
    • GET /v1/receipts/{orderNumber} → Retrieve full receipt details.
    • POST /v1/receipts/{orderNumber}/redeem → Redeem entitlements (full or partial).
  • USD support for Checkout Sessions: Checkout Sessions now accept collections in USD, expanding beyond local currency support.

​
💡 Common Use Cases

  • Verify a purchase – Retrieve a receipt by order number to confirm items, status, and timestamp.
  • Redeem event tickets or vouchers – Mark entitlements as redeemed at point of entry.
  • Partial redemption – Consume part of a multi-item receipt (e.g., ride credits, vouchers).
  • Full redemption – Mark a receipt as fully consumed to prevent reuse.
  • Checkout in USD – Allow merchants to receive funds in U.S. dollars.
