Original GitHub issue: https://github.com/binwiederhier/ntfy/issues/706

❓ Question
Is it possible from a web script (not having Ntfy as a private server) to create a topic where only one user can be subscribed?
Or, if it's not possible, having my own Ntfy server can I know how many subscribers a topic has, and reject or delete subscriptions if more than one?

Pubsub generally allows many subscribers, and ntfy does not implement subscriber limits per topic either.

Or, if it's not possible, having my own Ntfy server can I know how many subscribers a topic has, and reject or delete subscriptions if more than one?

Topic subscriptions are kept in memory and are not exposed in any way right now. I suggest you just create a user and reserve a topic, or you update your access controls manually to allow only the authorized user to access the topic.
