Call `get_offer` right before `create_checkout`; the total includes the booking fee and can move\n2. Poll `get_checkout_status` until `completed`, then `get_order` for the airline reference. A sent link isn't a booking\n3. Never ask for card numbers in chat. Hand over `checkout_url`, or pay it with a Link virtual card the user approved for the exact total\n4. Budget 100 searches a day per signed-in user, and use `search_multi_city` instead of many single searches\n5. Save the traveller once with `save_traveler` so later bookings don't re-ask for passport details\n\n### Hotelbeds Hotel Booking API\n\n1. Compute `X-Signature` fresh per request from key, secret and the current epoch seconds, in that order\n2. Budget the 50 daily evaluation calls; cache hotel content and only call availability for real dates\n3. Run CheckRate on a rate before booking when the availability response says it needs rechecking\n4. Read a 403 on the test host as the daily quota first, not a bad key\n5.
