[role="xpack"] [[watcher-api-ack-watch]] === Ack Watch API {xpack-ref}/actions.html#actions-ack-throttle[Acknowledging a watch] enables you to manually throttle execution of the watch's actions. An action's _acknowledgement state_ is stored in the `status.actions..ack.state` structure. [float] ==== Request `PUT _xpack/watcher/watch//_ack` + `PUT _xpack/watcher/watch//_ack/` [float] ==== Path Parameters `action_id`:: (list) A comma-separated list of the action IDs to acknowledge. If you omit this parameter, all of the actions of the watch are acknowledged. `watch_id` (required):: (string) Identifier for the watch. [float] ==== Authorization You must have `manage_watcher` cluster privileges to use this API. For more information, see {xpack-ref}/security-privileges.html[Security Privileges]. [float] ==== Examples To demonstrate let's create a new watch: [source,js] -------------------------------------------------- PUT _xpack/watcher/watch/my_watch { "trigger": { "schedule": { "hourly": { "minute": [ 0, 5 ] } } }, "input": { "simple": { "payload": { "send": "yes" } } }, "condition": { "always": {} }, "actions": { "test_index": { "throttle_period": "15m", "index": { "index": "test", "doc_type": "test2" } } } } -------------------------------------------------- // CONSOLE // TESTSETUP The current status of a watch and the state of its actions is returned with the watch definition when you call the <>: [source,js] -------------------------------------------------- GET _xpack/watcher/watch/my_watch -------------------------------------------------- // CONSOLE The action state of a newly-created watch is `awaits_successful_execution`: [source,js] -------------------------------------------------- { "found": true, "_id": "my_watch", "status": { "version": 1, "actions": { "test_index": { "ack": { "timestamp": "2015-05-26T18:04:27.723Z", "state": "awaits_successful_execution" } } }, "state": ... }, "watch": ... } -------------------------------------------------- // TESTRESPONSE[s/"state": \.\.\./"state": "$body.status.state"/] // TESTRESPONSE[s/"watch": \.\.\./"watch": "$body.watch"/] // TESTRESPONSE[s/"timestamp": "2015-05-26T18:04:27.723Z"/"timestamp": "$body.status.actions.test_index.ack.timestamp"/] When the watch executes and the condition matches, the value of the `ack.state` changes to `ackable`.

This happens when the condition of the watch is not met (the condition evaluates to `false`).
