# Add trigger

Available in Classic and VPC

Here is an example to help you understand how to add triggers that run actions. This example creates a trigger that updates user location and calls the hello action when the user location is updated. For learning this example, see the following guides:

- How to create an action
  - Cloud Functions > Action > Create action

## Create action

1. Write source code that receives and outputs name and location.

```
function main(params) {
    return {payload:  'Hello, ' + params.name + ' from ' + params.place};
}
```

1. Create an action in the console using the source code written in step 1.

## Add trigger

You can add a trigger that runs actions as follows:

1. Go to action details by selecting the action named helloAction created in the console.

2. Click **[Add]** in the trigger section.
3. Select **Create new** for connection method and select **API Gateway** for type.

4. Configure settings to create API Gateway endpoint that will call the action through API Gateway.

## Check run results

You can run the trigger and check if the action runs properly. To check, take the following steps:

1. Run the action by calling the API Gateway endpoint. For detailed run methods, see [Run trigger in API Gateway trigger](/docs/en/cloudfunctions-apigateway-vpc#%ED%8A%B8%EB%A6%AC%EA%B1%B0%EC%8B%A4%ED%96%89).

```
curl -X POST -H "Content-Type: application/json" https://func.apigw.ntruss.com/api/v1/hello?blocking=true&result=true -d '{"name": "Cloud Functions", "place": "NAVER Cloud"}'
```

1. Check detailed information about run results in the **Monitoring** tab menu of the action details screen. Check if the action ran by viewing the most recent activation information and verify that the action triggered processes parameters correctly.
