I've done some research regarding the matter, I can see that you can use SOAP or RESTful APIs to make a web application using PHP. However what I want to accomplish here is to make a red app that can be used with sabre workspace.
I'm not familiar with the work space, i just started learning about it, I've downloaded the developer toolkit and read the documentation, from this I came to the conclusion that the app has to be written in java in order to work with sabre workspace.
I wanted to make sure if that's the only way of doing it.
your help is highly appreciated. Thanks.
