Mark an alert signal as read.

Rate Limit: No endpoint-specific limit

Marks an alert signal as read, setting its isRead flag to true. An alert signal is a single trigger event produced by an alert — the moment the alert's condition was met. Marking it read acknowledges that the user has seen the notification. Identify the signal with alertSignalId (the integer entity ID); supply the owning alert's ID in alertId.

To look up the parent alert, query alertItem or alertItems.

On success, the response returns with an empty errorText. On a handled failure, the response carries a non-empty errorText describing the problem.

Common Failure Scenarios

• The alertSignalId doesn't exist or isn't accessible to the caller.
• The access token is missing or invalid (returns HTTP 401).
