Steps
Authenticate to the Expedia Rapid API using API key and secret in the request signature
GET /v3/properties/{propertyId}/rooms to confirm room and property linkage before cross-sell
Call the Expedia Flights Seatmap endpoint with the itinerary ID and segment reference

Map seatCharacteristics codes (window, aisle, exit-row, no-recline) to user-facing labels
Return selected seat IDs for inclusion in the ancillary booking step
Known gotchas
Expedia Rapid primarily serves accommodation; flight add-ons including seatmap are available through a separate Expedia Travel API product that requires a distinct partner agreement
Seatmap responses vary by airline content source; some carriers provide full deck-level detail while others return only cabin-level occupancy counts
Seat characteristic codes are not standardized across airlines in the Expedia system; a code that means 'extra legroom' for one carrier may mean 'exit row restriction' for another
