Events

Each event is delivered as a flat JSON body. See Webhooks for setup, retries, and duplicates.

Event list

Event	Fires when
`push.completed`	An action reaches `completed`.
`push.failed`	An action reaches `failed`.
`device.connected`	An end user links a new device through Link UI.
`device.reconnected`	An end user links a device that was already connected.
`device.disconnected`	The device’s manufacturer credentials stop working.

Coming soon. Events for recurring schedules.

Identify the event

The body has no event type field. Branch on the fields present.

function eventType(event: Record<string, unknown>): string {
  if ("actionId" in event) return "errorCode" in event ? "push.failed" : "push.completed";
  if ("reconnectionUrl" in event) return "device.disconnected";
  return "device.connected or device.reconnected";
}

device.connected and device.reconnected have the same fields. If you need to tell them apart, check whether you already know the deviceId.

push.completed

The manufacturer accepted the command.

{
  "actionId": "action_qjSucnQFAk",
  "deviceId": "device_abc123",
  "deviceType": "battery",
  "command": "charge",
  "parameters": { "target": { "value": 80, "unit": "percent" } },
  "result": { "success": true },
  "completedAt": "2026-05-07T10:30:05.000Z"
}

Field
`actionId`	The action. Same as `id` on `GET /actions/{id}`.
`deviceId`	The device.
`deviceType`	`battery`, `ev_charger`, or `hvac`.
`command`	The command you sent.
`parameters`	The parameters you sent, or `null`.
`result`	`success` is `true`. A short `message` may be present.
`completedAt`	When the action completed.

push.failed

The command didn’t succeed. Branch on errorCode.

{
  "actionId": "action_qjSucnQFAk",
  "deviceId": "device_abc123",
  "deviceType": "battery",
  "command": "charge",
  "parameters": { "target": { "value": 80, "unit": "percent" } },
  "result": { "success": false, "error": { "code": "DEVICE_OFFLINE", "message": "The device is currently offline at the manufacturer." } },
  "errorCode": "DEVICE_OFFLINE",
  "errorMessage": "The device is currently offline at the manufacturer.",
  "failedAt": "2026-05-07T10:30:05.000Z"
}

Same fields as push.completed, except:

Field
`result`	The error, or `null`. Don’t rely on it. Use `errorCode`.
`errorCode`	Why it failed. See Error codes.
`errorMessage`	Human-readable. Don’t parse it.
`failedAt`	When the action failed. Replaces `completedAt`.

device.connected

{
  "deviceId": "device_abc123",
  "deviceType": "battery",
  "timestamp": "2026-05-07T10:30:00.000Z"
}

Field
`deviceId`	The device.
`deviceType`	`battery`, `ev_charger`, `hvac`, `solar_inverter`, or `vehicle`.
`timestamp`	When the event happened.

device.reconnected

Same fields as device.connected.

{
  "deviceId": "device_abc123",
  "deviceType": "battery",
  "timestamp": "2026-05-07T12:00:00.000Z"
}

device.disconnected

Sent when a read or command fails with INVALID_CREDENTIALS. A failed command also sends its own push.failed.

{
  "deviceId": "device_abc123",
  "deviceType": "battery",
  "timestamp": "2026-05-07T11:00:00.000Z",
  "reconnectionUrl": "https://auth.amps.ai/app_abc123?manifestId=battery_example&reconnect=true"
}

reconnectionUrl opens Link UI so the end user can reconnect. It’s usually present but can be missing, so handle both cases.
