External Application and Joom Credits

Hello!

I read many good things about Joom Credits and it's really what i'm looking for. but i wanna know one last major matter to me to proceed and buy the component.

I have an external application (conected with joomla), which with it, i would like to be able to change the credit values for each user, depending of the usage of this application. Is this possible??

Many thanks for your time!!!
