Agent Metadata
Known Gotchas
- ⚠ Sandbox and production use different credentials — never mix them up
- ⚠ Access tokens expire after 8 hours — agents must refresh before expiry
- ⚠ PayPal v1 and v2 APIs coexist — prefer v2 (Orders, Subscriptions, Payouts)
- ⚠ Webhook verification requires signature validation — critical for payment security
- ⚠ Currency handling requires ISO 4217 codes and decimal precision varies by currency
- ⚠ Seller onboarding (for marketplaces) is complex — requires separate OAuth flows
