I think you can do this using their API as c-cex also provide api access but you have to build script for this from scratch by yourself or you have to hire someone who have enough experience on working with api.
I can make anything from scratch as long as I know what I'm looking at. If I knew the address to the coin transfer, amount and button within C-Cex balance and implement that I could write a php or jquery script around it on my site.
