I suggest you look into something called IMS LTI. Here is a good video introduction to it:

Before IMS LTI in order to hook into Moodle you needed to write a Moodle plugin. But using IMS LTI you should be able to just enter in some details about your app, like the url and a shared key and using IMS LTI user data and responses should be passed between Moodle and your app. Future versions of the IMS LTI standard will also allow you to pass grading information.
