I can understand why they do it, it's enterprise software so the more open you make it, then the less licences they can sell.

They do have a module you can purchase to run API calls and access their files/software but as you probably guessed that's another $40k license!

Most of my apps I build use this API, but for me to provide to other companies they need them to also buy the API extension.

I'd love to cut out the middle man and I'll do it eventually when I reverse engineer the header!
