Hi Everyone, my company developed an App for back pain. The app is designed for patients (end users) that can use it to do excercises to get some relief. Patients can purchase extra-exercises or services. I want to explore the possibility that third parties (eg. Hospitals, Gyms, Assurances) can purchase the extra-contents on behalf of patients. I know there is VPP but it is only for paid apps not for free apps with in-app purchase. There is a way to give credit or voucher spendable only for my app? any other suggestion? I thank anyone who can help me
