• Webhook Handling: Implements secure endpoints to process asynchronous payment events (e.g., successful payouts, disputes).
• Security & Compliance: Provides code patterns that enforce PCI compliance by never logging sensitive cardholder data.
• Resilience Engineering: Builds in idempotency keys and comprehensive retry logic for failed transactions.

Example Use Cases
