Hotel Channel Manager & OTA API Integration -- 2

I work on own PMS SaaS platform.

Need to create a Hotel Channel Manager microservice where PMS inventory is synced with OTA platforms. The Channel Manager should work on real time basis.

The Hotel Channel Manager should allow maintain hotel's rate and availability across numerous third-party sales sites simultaneously, including majar global OTAs: Booking.com, Agoda, hotels.com, Expedia, Trivago, TripAdvisor, and some of the local domestic OTAs (TBD).

Please bid only if you already worked on such project before, or you have a ready, or semi-ready solution. Please start your reply with pointing that you have experience in OTA Channel Manager development and list OTAs with which you worked.

Experience of developing OTA Channel Managers needed

Initial tasks:
- consult what data synchronization standards are used in popular OTAs;
- consult what data format is used there (XML, JSON, B.XML, etc.);
- split OTA into groups according to criteria: a) by markets (global, domestic); b) similar protocol, format and structure of OTA APIs; and etc.
- research on additional OTAs (CIS countries): find information on how to integrate with them (protocol, format and data structure). If the information is not publicly available - request through support.
- draw up a technical specification/implementation plan.

After analysis, systematization of information and preparation of requirements, it will be possible to start implementation.

Thanks
