About OneSignal's OneSignal API
OneSignal's OneSignal API sends push, email, and SMS notifications through OneSignal. OneSignal is a customer engagement platform for messaging. The OneSignal API is used by developers worldwide for push notifications, email, SMS, user engagement.
Probecast monitors the OneSignal API from 4 global regions (US West, US East, Europe, Asia Pacific) every 300 minutes, tracking uptime, latency and regional availability. Our real-time monitoring helps developers and teams understand the current health of OneSignal's OneSignal API and get alerted the moment service degrades.
Why monitor OneSignal API?
If your product depends on OneSignal API for critical features, an outage on OneSignal's side is an outage on your product. Probecast detects OneSignal API incidents as they start, giving you time to communicate with customers, fall back to alternative services or pause background jobs gracefully.
