Before you call either

Duffel Flights and Stays API

  1. Send Duffel-Version: v2 on every request or you get a version error
  2. Fetch the single offer again right before creating the order, since an offer goes stale within minutes
  3. Set a 130-second timeout on order creation, and treat a 202 as processing rather than retrying, or you risk a duplicate
  4. Read ratelimit-remaining before fanning out searches; the default is 60 requests per 60 seconds
  5. Count offer requests. Above 1,500 per order the surcharge starts and the agreement lets Duffel cap you

LiteAPI (Nuitee Connect)

  1. Use /hotels/rates with a short hotelIds list from /data/hotels; a broad rates call is slow and large
  2. Always prebook before book and read the cancellation policy in the prebook response, since refundability differs per rate
  3. Send a unique clientReference on book; a repeat returns error 4005 instead of a second booking
  4. Set margin explicitly on every rates call. Zero means net rates with no commission to you
  5. Send the key to the MCP in an X-Api-Key header rather than ?apiKey= where the client allows it
