Learn how to send Signalgrid push notifications
Signalgrid makes it straightforward to send notifications from Shell Scripts. The platform uses a simple model built around your client_key, a target channel, and a few core fields such as title, body, type, and optional critical.
Shell scripts are still everywhere. Signalgrid makes it easy to add simple notification delivery to scheduled tasks, maintenance jobs, and system scripts.

- A Signalgrid account
- Your client key
