# For Each: Exemplo de uso
Aprenda um exemplo de uso do componente For Each.
O objetivo do componente **For Each** é percorrer um *array* JSON e, para cada item do *array*, acionar um *subpipeline*. Para mais informações sobre o componente e seus parâmetros, [veja a documentação do For Each](/documentation/connectors-and-triggers/pt-br/connectors/logic/for-each.md).
Dê uma olhada no cenário de uso suportado a seguir:
1. Obtenha um exemplo de JSON *array* através de uma chamada ao seguinte endereço: .Para este passo, utilize também o componente [**REST V2**](/documentation/connectors-and-triggers/pt-br/connectors/web-protocols/rest-v2.md).
2. O resultado da execução descrita no passo anterior deve retornar uma lista de endereços. Esses endereços estão contidos no objeto `"body"`. Observe:
```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"
}
}// Some code
```
3. Com uma lista para o **For Each** percorrer, arraste o ícone do componente até a área de construção do *pipeline*.
4. Clique no ícone do **For Each** para abrir as suas configurações e especificar a expressão JSON Path. É por meio dessa expressão que:
* se especifica o *array* a ser iterado;
* se adicionam filtros para iterar outros itens.
**Exemplos:**
* **$.body.\*:** percorre o *array body* inteiro.
* **$.body.\[?(@.bairro == ‘Cristo Redentor’)].\*:** percorre o *array* somente quando o atributo `"bairro"` for igual a `"Cristo Redentor"`.
5. Acesse o ícone do **For Each** novamente para configurar o *subpipeline* de execução para cada linha.
{% hint style="info" %}
É necessário existir ao menos um componente no *subpipeline*.
{% endhint %}
6. Após desenhar o fluxo, execute o *pipeline* e observe que na saída do JSON é demonstrado um totalizador de execução. Para que a execução seja contabilizada com sucesso, adicione a mensagem *`"success" : true`* no último passo do *subpipeline*.
**Exemplo:**
Copie o conteúdo abaixo e cole na sua área de construção do *pipeline* utilizando o comando **Ctrl + v** (se utilizar Windows) ou **Command + v** (se utilizar MAC).
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.digibee.com/documentation/connectors-and-triggers/pt-br/connectors/logic/for-each/for-each-example-of-use.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
