Hello there! Sorry for the delay in responding. I wanted to get a good look at where things went wrong. It appears that, for some reason, the documentation is pointing to the wrong endpoint to delete a subscription. The badges endpoint deals with user badges.
Here is a detailed guide to help you get accustomed to user subscriptions: https://developer.khoros.com/khoroscommunitydevdocs/docs/delete-a-subscription-by-target-id
I'm also updating the existing API reference ( https://developer.khoros.com/khoroscommunitydevdocs/reference/delete-user-subscription ) to correct the error. Thank you for bringing this to our attention.
