Edesy OnCall gives you a webhook URL for Prometheus Alertmanager or Grafana alerting. Route your critical alerts to it and each firing alert opens an incident that phones your on-duty engineer in English or Hindi, escalating until someone presses 1. A resolved alert closes the incident. Keep chat and email for everything else.

What happens to an alert your stack sends
| Item | Edesy OnCall |
|---|---|
| Endpoint | POST https://oncall.edesy.in/ingest/<token>, one URL per alert webhook monitor |
| Formats | Prometheus Alertmanager webhook, Grafana alerting webhook, Uptime Kuma, or generic JSON; detected automatically |
| Firing alert | Opens an incident (or updates the open one with the same key) and starts the monitor's escalation policy |
| Resolved alert | Closes the matching incident; paged contacts get a back-up email |
| Grouping | By Alertmanager fingerprint, or alertname + instance + job when there is no fingerprint |
| What the call says | The alert's summary annotation, or its alertname, plus your organisation name |
| Limits | 120 requests a minute per IP, 1 MB body |
Your stack keeps doing the detection
In OnCall, add an Alert webhook monitor, attach an escalation policy and copy its URL.
In Alertmanager, add a webhook_configs receiver with send_resolved: true. In Grafana, add a Webhook contact point.
Send severity=critical (or your equivalent) to the OnCall receiver, and keep warnings in chat or email.
Set a short summary annotation such as "Checkout API error rate above 5%". It is what the on-call engineer hears.
Fire a test alert from Grafana or amtool and check the incident timeline in OnCall.
Chat channels get muted, and email is read in the morning
Press 1 tells the team someone owns the incident
A second step calls the next engineer if the first is asleep
Hindi alerts for teams who prefer them
Detection, thresholds and alert rules stay in Prometheus or Grafana
Chat notifications stay in your existing contact points
OnCall has no schedules or rotations: edit the policy when duty changes
No SMS, Slack or Teams from OnCall: calls and email only
