Welcome to the Google Home Developer Center, the new destination for learning how to develop smart home actions. Note: You'll continue building actions in the Actions console.


If the user unlinks your smart home Action from Google Assistant, your fulfillment receives an action.devices.DISCONNECT intent. This intent indicates that Assistant will not send any more intents for this user, and your cloud service should stop calling Google Home Graph APIs (Request Sync and Report State) for their devices.

    "inputs": [{
      "intent": "action.devices.DISCONNECT",
const {smarthome} = require('actions-on-google');
const app = smarthome();
// ...
app.onDisconnect((body, headers) => {
  // TODO Disconnect user account from Google Assistant
  // You can return an empty body
  return {};
public void onDisconnect(
    @NotNull DisconnectRequest disconnectRequest, @Nullable Map<?, ?> map) {
  // TODO Disconnect user account from Google Assistant
  // This function does not return anything

For more information, see the DISCONNECT intent reference documentation.
