Hi, I'm trying to integrate an external mobile application into Blackboard, which needs to integrate with membership, roles, and grading components (apologies if my terminology is incorrect, I'm new to Blackboard development). I've seen the Office Hours about the new RESTful APIs, and they sound really interesting. However, one thread notes that this is only for SaaS customers, and not self or managed solutions. I've found that the Grades Journey building block also opens up some RESTful endpoints, so that is one possible solution for us. Are there other Building Blocks or ways to tap into the Blackboard enrollment and roles data?
