I am looking for API or way to upload an image directly to a playlist image within the Music App from my app. Any idea how this is done? I can create the names of the playlists and transfer them over, I just can’t get my images to transfer over. Any insights?

I am looking for an API that allows me to gift a subscription to another app from my app. Example: There is an app Swortkit Fitness and I have a subscription for it. I want to create an App that allows me to gift similar workout apps that require subscriptions to other Apple users. I looked in StoreKit, but I am not seeing if this is possible or if there is an API and Documentation out there. Again, I want to use my app with the StoreKit framework and In-App Purchase to purchase a subscription to another user. How would this be done and is there an API and documentation on this?Thanks
