Choose a topic

A topic is a name you make up. Alertified sends to https://ntfy.sh/<your topic>.

• Use only letters, numbers, dashes (-) and underscores (_). No spaces, dots or slashes.
• Enter it in Alertified exactly as you subscribed to it in the ntfy app.

Pick a hard-to-guess topic

On ntfy.sh, anyone who knows a topic name can subscribe to it and read its messages. Choose a long name nobody would guess, such as acme-stock-7f3k9q2xw4, rather than my-shop-alerts.
