Selling tickets via API/3rd party ticket sites

Hi everyone,

We are exploring selling tickets via API through Tripadvisor and some of the other companies listed here on Tessitura's list of "alternative sales channels".

https://www.tessituranetwork.com/en/Services/Partnerships/Alternative-Sales-Channels

• CityPass
• Goldstar
• Ingresso
• SeatGeek
• StubHub
• TodayTix
• Travelzoo
• TripAdvisor
• VetTix

Are any of you selling tickets through API with any of these companies? Or, have you attempted to but found obstacles (internal, union box office, etc.)?

I'd love to speak with you. 

Thanks,

Chuck Buchanan
