How to create a detail alert message via webhook?

Hi Friends,

I need help to create an alert on grafana.
Now, I have success to create an alert via webhook but I have the alert message issue. How to add metric value in the alert message? How about the tag name and value?

the answer hre depends on what Grafana version you are using, and what version of alerting you are using: legacy alerts, alertng, of the fully-released Unified Alerting in 8.2+
