Transavia Airlines is a Netherlands-based low-cost air travel operator that boasts an expansive route network in the European and North African regions. The Transavia Flight Offer API is one of the three air travel APIs that the company uses to supplement its web-based engagement portals. This API allows developers to build searchable platforms for ticket offers for different flight schedules, trips, and destinations. This enables travelers to check for availability of the most affordable tickets that best suit their travel schedules. The API conveys requests and responses in HTTP and JSON formats.
