Had a look at their documentation and it seems that in PHP, we cant do all request via the REST service.
For example:
I could fetch flights by REST (Instaflights Search)
But when I want to book something, I need to jump into SOAP (Book Air Segment)
I would prefer to do everything in REST rather than SOAP or half and half.
Is this the right way to create a booking engine? Or I am missing something?
Sabre is working on developing REST Booking API. At this moment only available using SOAP technology.
Instaflights is available on REST only, not SOAP. But Pnr creation will have to be on SOAP only, for now.
