Creating OTRS web mobile interface

at the company where I work, we use OTRS to schedule tickets and such. But the web interface is not very intuitive and easy to use, particularly on mobile...

Is it possible to create my own mobile version of OTRS? I mean, I can create a website that is mobile optimised and easy to use, but is there an API to communicate with OTRS?

I've only seen simple scripts to create tickets via soap or rest interface, I need to create a ticket, show a list of the user tickets and close them, postpone them...

Thank you in advance
