## Before you call it

1. Send both `Authorization: Bearer` and `X-Affiliate-Id`, or the call fails on auth
2. Stay under 50 requests a minute in the sandbox and back off exponentially on 429
3. Only accommodation flows book in the sandbox; cars and attractions won't
4. Store the key at creation, it's never shown again
5. Use filters and pagination on search to keep payloads small
