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

Lola

  1. Have the traveller confirm booking details, charges and cancellation terms.
  2. Check whether a membership benefit is live before relying on it.
