Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Obtain an OAuth 2.0 access token from the Sabre token endpoint using client credentials
Construct a BFM JSON request body with OD pairs, passenger types, and TPA_Extensions for carrier include/exclude lists
Add PenaltyRestrictions element with ChangePenalty and CancelPenalty max-amount filters
POST to /v4/offers/shop and inspect the groupedItineraryResponse envelope
Iterate legs and pricingInformation arrays to surface the lowest combinable fare per carrier
Cache the SequenceNumber and BookingCode for the chosen itinerary before moving to price verification
Known gotchas
BFM returns grouped itineraries by default; set TPA_Extensions/IntelliSellTransaction/RequestType to 'AD1' for single-itinerary mode when you need per-solution pricing
The token endpoint returns a ConversationID that must be echoed in subsequent requests in the same session to maintain context
Penalty filter amounts are in the POS currency; results from multi-POS deployments will vary unless you pin PointOfSaleOverride
