Grafana Webhooks

Covers the Grafana Alerting webhook contact point (Grafana-managed alerting, the only alerting system in Grafana 11+; also Grafana Cloud).

Not covered: Grafana legacy dashboard alerting webhooks (removed in Grafana 11 — different payload with ruleName/evalMatches, no HMAC); Grafana OnCall / IRM outgoing webhooks (separate product, own templates and auth); Prometheus Alertmanager webhook_config (payload is a close relative — Grafana's is Alertmanager's plus extra fields — but Alertmanager has no HMAC signing).

When to Use This Skill

• How do I receive Grafana alert webhooks?
• How do I verify a Grafana webhook signature?
• What is X-Grafana-Alerting-Signature and how do I check it?
• Why is my Grafana webhook HMAC verification failing?
• How do I tell a firing alert from a resolved one in the Grafana payload?
• How do I secure a Grafana webhook contact point (HMAC, basic auth, bearer token)?
