Agent pitfalls & tips
- IMPORTANT: Request body uses form-encoded, NOT JSON (despite JSON responses).
- Always use Payment Intents API over legacy Charges API.
- Test card numbers: 4242424242424242 (success), 4000000000000002 (decline).
- Amounts are in smallest currency unit: 2000 = $20.00 USD, 2000 = ¥2,000 JPY.
- Idempotency-Key header prevents duplicate charges on retries.
- Webhooks: verify signature with endpoint secret for security.
