# For Each: Usage example
The objective of the **For Each** component is to go through an JSON array and, for each array item, trigger a subpipeline. For more information about the component and its parameters, [refer to the For Each documentation](https://docs.digibee.com/documentation/connectors-and-triggers/connectors/logic/for-each).
Take a look at the supported usage scenario below:
1. Obtain an example of JSON array through a call to the following address: . For this step, use the [**REST V2**](https://docs.digibee.com/documentation/connectors-and-triggers/connectors/web-protocols/rest-v2) component as well.
2. The result of the execution described in the previous step must return an address list. These addresses are in the `"body"` object. See:
```json
{
"status": 200,
"statusMessage": "OK",
"body": [
{
"cep": "91420-270",
"logradouro": "Rua São Domingos",
"complemento": "",
"bairro": "Bom Jesus",
"localidade": "Porto Alegre",
"uf": "RS",
"ibge": "4314902",
"gia": "",
"ddd": "51",
"siafi": "8801"
},
//omitted
],
"headers": {
"Access-Control-Allow-Credentials": "true",
"Access-Control-Allow-Headers": "Content-Type, X-Request-With, X-Requested-By",
"Access-Control-Allow-Methods": "GET",
"Access-Control-Allow-Origin": "*",
"Access-Control-Max-Age": "86400",
"Cache-Control": "max-age=3600, public",
"Connection": "keep-alive",
"Content-Type": "application/json; charset=utf-8",
"Date": "Fri, 24 Nov 2023 15:20:41 GMT",
"Expires": "Fri, 24 Nov 2023 16:20:41 GMT",
"Pragma": "public",
"Server": "nginx/1.22.0",
"Transfer-Encoding": "chunked"
}
}
```
3. With a list for **For Each** to go through, drag the component icon to the pipeline building area.
4. Click on the **For Each** item to open its configurations and specify the JSON Path expression. Through this expression is possible to:
* specify the array to be iterated.
* add filters for other items to be iterated.
**Examples:**
* **$.body.\*:** goes through the whole array body.
* **$.body.\[?(@.bairro == ‘Cristo Redentor’)].\*:** goes through the array only when the attribute `“bairro”` is equal to `“Cristo Redentor”`.
5. Access the **For Each** icon again to configure the execution subpipeline for each line.
{% hint style="info" %}
At least one component must exist in the subpipeline.
{% endhint %}
6. After designing the flow, execute the pipeline and observe that in the JSON output an execution totalizer is shown. For the execution to be accounted as successful, add the `"success" : true` message in the last step of the subpipeline.
**Example:**
Copy the content below and paste in your pipeline building using **Ctrl + V** (if using Windows) or **Command + v** (if using MAC).
{% code fullWidth="true" %}
```
