Documented steps
Authenticate. Use GET {base}/activities - activities are the superset of all alarms and audits in the system.
Narrow by activityType (array, values alarm and audit, maximum 2 entries) and by time with startTime and endTime (ISO-8601 date-times).
Filter alarms by severity with priorityRange, which must match the pattern ^\d+,\d+$ - a comma-separated pair within 0-255 and no space, e.g. priorityRange=0,70.
Scope by asset with the equipment, object and space array parameters (each capped at 100 ids), and by alarm type with the type parameter (values from alarmValueEnumSet, e.g. alarmValueEnumSet.avHighLimit, up to 100).
Control acknowledgement visibility with includeAcknowledged, includeAcknowledgementRequired (default true) and includeAcknowledgementNotRequired (default true); include closed items with includeDiscarded.
Sort with sort (creationTime, -creationTime, priority, -priority; default creationTime). Page by passing the continuationToken from the previous response - this endpoint uses a continuation token, not page/pageSize.
Acknowledge an alarm with PATCH {base}/alarms/{alarmId} and body {"activityManagementStatus":"acknowledged","annotationText":"acknowledged by automation"}. Expect 204 No Content.
Close an alarm with the same PATCH using "discarded". Discarded is terminal - the alarm cannot move to any other state afterwards.
For a live feed, open a stream and reissue GET /activities with header METASYS-SUBSCRIBE: {streamId}; filters on the GET also filter the subscription. Cancel with DELETE on the returned METASYS-SUBSCRIPTION-LOCATION (/activities/streams/{streamId}/subscriptions/{subscriptionId}).

Known gotchas
GET /alarms and GET /audits were removed in the Metasys 14.0 release of API v6 - a breaking change. The replacement is GET /activities?activityType=alarm or activityType=audit. Code written for v5 will 404.
/activities does not accept page and pageSize; it pages with continuationToken. The token is ignored for streaming subscriptions.
An alarm can only be acknowledged when activityManagementStatus is currently 'pending' and isAckRequired is true. Any other combination returns 400, including a second acknowledgement of an already-acknowledged alarm.
Successful acknowledgement returns 204 with no body - do not parse a response payload.
Streaming filter behavior has a deliberate exception: you receive activity.alarm.discard and other management-status events even when your filters exclude discarded items, because the change affects activities you already received. Handle these or your client state drifts.
Activity stream event names are activity.heartbeat (every 120 seconds), activity.alarm.new, activity.alarm.ack, activity.alarm.annotate, activity.alarm.discard, activity.audit.new, activity.audit.annotate and activity.audit.discard. Audits have no ack event because audits cannot be acknowledged.
priorityRange is validated against a strict regex; 'priorityRange=0, 70' with a space fails.
