Notes & Best Practices

Tokenized payments: Use this endpoint for returning customers; no card data should ever be re-entered.
CVV handling: Some issuers require CVV for stored card transactions — always respect the API’s response and re-submit only if prompted.
Security: Never store or log the CVV. Only keep customerToken and subscriptionToken for future use.
Idempotency: Avoid duplicate charges by tracking TransactionToken at your application level.
Response validation: Always verify both Result and ResultExplanation before updating payment status.
Error recovery: Retry only when safe (e.g., for transient 888 errors). Avoid retrying on verification or data mismatch errors.
