Creates a new alert from a predefined template. At least one delivery method is required:
a callbackUrl (direct webhook) or one or more connectorIds (Slack, email, SMS, etc.).
You can use both simultaneously.

The alert is compiled into a stream subscription internally — the delivery engine handles
matching and delivery with retries.

Alert state

• armed — The alert is actively watching for its condition.
• triggered — The condition was detected and the alert fired. For threshold_crossing
  suppression mode, the alert stays triggered until the value recovers past the threshold.

Example: CC balance alert

{ "templateId": "cc-balance-low", "params": { "party": "noves-validator-1::1220...", "threshold": 5000, "comparison": "below" }, "connectorIds": ["your-slack-connector-id"] }

Example: Large CC transfer alert with webhook

{ "templateId": "cc-transfer-amount", "params": { "party": "noves-validator-1::1220...", "amount_threshold": 100, "direction": "both" }, "callbackUrl": "https://your-server.com/alerts" }
