How can I send notifications to users using Ntfy but prevent them to
write into the topic?
reddit / selfhosted

Hi. If I wanted to send manual push notifications to a team of people
using ntfy, how can I make sure they can subscribe and read the topic
but only I can send the notifications with POST? I have already tried
researching the docs, but I can't find anything and I don't seem to
understand it. Thank you.

From what I’m seeing that isn’t how ntfy works.  Nfty simple pushes a
notification of some event you’ve tied into it - there is no
read/write function at all.

What are you pulling the notifications from?

Ntfy provides a `ntfy` command-line tool which can be used to
configure many things about the ntfy service, including [access
control](https://push.sairaag.com/docs/config/#access-control).

For example, if you had an `announcements` topic:

1. `ntfy access everyone announcements read` sets the `announcements`
topic globally read-only.
1. use `nfty user add ` to create a user for yourself.
 * You might also want to `ntfy token add ` to generate an access
token for yourself to use for pushing.
1. `ntfy access  rw` to grant yourself read+write to the
`announcements` topic.

If you're running ntfy inside a docker container, you can run the
`ntfy` CLI tool by `docker exec  /usr/bin/ntfy`

it does have read/write permissions if you selfhost it. i haven't
tried the hosted version but the dev has added password protected
channels for public topics.

No, it’s pub/sub. Look into MQTT.
