Hello, my question may be a little bit stupid because I have no experience at all on using websockets.

I need to stabilish a connection between two PHP servers using Laravel, it works this way :

I have a central server, wich works as an API that will update every 10 minutes, but it can also update anytime if some changes are needed, and I need this change to be reflected instantly into other "Client Servers"

I tried doing it with websockets using laravel-websockets, redis, pusher and a bunch of other stuff on the central server, and all worked fine.
But every single tutorial I see on the internet uses like SocketIO or Laravel Echo wich both are js solutions, I need to listen to these events without using a browser, no front-ends involved

How Can I achieve this? really need help
Sorry for any english errors as it's not my primary language
