"Receive messages on Signal via a simple API. Perfect for notifications and alerts."

"curl -d ' Houthi alert' https://signalbot.one/api/..."

If you don't know what "API" or "webhooks" are, then you're probably not the target audience. That's fine. Your aunt probably doesn't know what an "enterprise workload engine"[1] is, but that doesn't mean vmware needs to provide a dumbed down description so everyone can understand.
