My guess is that those integration points are intended to be used by University owned and operated services. Having a service that the University doesn't control wanting to do this would be difficult to get approval. Student data is highly protected (legally), so access to it through another application (where the operators could see other students' data) is problematic.
That makes sense. Now, with that in mind, a reasonable response to OP's request would involve just saying "no". Maybe even politely explain why, but that isn't required.
