### JavaScript Example for API Integra Contador

Source: https://apicenter.estaleiro.serpro.gov.br/documentacao/api-integra-contador/pt/solucoes/integra-sn/pgdasd/exemplos/retorno_entregar_declaracao

This JavaScript example illustrates how to make a GET request to the API Integra Contador using the Fetch API. It handles the response asynchronously and logs the JSON data to the console. This code is suitable for browser-based or Node.js environments.

```javascript
const apiUrl = 'http://example.com/api/integra-contador';

async function fetchContadorData() {
  try {
    const response = await fetch(apiUrl, {
      method: 'GET',
      headers: {
        'Accept': 'application/json'
      }
    });

    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }

    const data = await response.json();
    console.log('API Response:', data);
    return data;
  } catch (error) {
    console.error('Error fetching data:', error);
    return null;
  }
}

fetchContadorData();

### Data Retrieval Example in Python

Source: https://apicenter.estaleiro.serpro.gov.br/documentacao/api-integra-contador/pt/solucoes/integra-sn/pgdasd/exemplos/retorno_consultar_extrato_do_das

This Python snippet demonstrates how to retrieve data using the API. It assumes the necessary authentication and request libraries are installed. The output is typically a JSON object representing the requested data.

```Python
import requests

def get_data(api_url, api_key):
    headers = {
        "Authorization": f"Bearer {api_key}"
    }
    response = requests.get(api_url, headers=headers)
    response.raise_for_status()  # Raise an exception for bad status codes
    return response.json()

# Example usage:
# api_endpoint = "https://api.example.com/data"
# auth_token = "YOUR_API_KEY"
# data = get_data(api_endpoint, auth_token)
# print(data)
```

### JavaScript: Making an Asynchronous API Request

Source: https://apicenter.estaleiro.serpro.gov.br/documentacao/api-integra-contador/pt/solucoes/integra-parcelamento/parcmei/servicos/exemplos/retorno_emite_das

This example shows how to perform an asynchronous GET request to an API endpoint using the `fetch` API in JavaScript. It includes basic error handling for network issues and non-OK HTTP responses.

```javascript
async function getApiData(url) {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }
    const data = await response.json();
    return data;
  } catch (error) {
    console.error('Error fetching API data:', error);
    return null;
  }
}

// Example usage:
// const apiUrl = 'YOUR_API_ENDPOINT';
// getApiData(apiUrl).then(data => {
//   if (data) {
//     console.log(data);
//   }
// });
```

### Python API Integra Contador Example

Source: https://apicenter.estaleiro.serpro.gov.br/documentacao/api-integra-contador/pt/solucoes/integra-sn/pgdasd/exemplos/retorno_gerar_das

This Python code snippet shows how to use the requests library to make a GET request to an API endpoint. It handles potential exceptions and prints the response status code and body. Ensure the 'requests' library is installed (`pip install requests`).

```python
import requests

url = "http://example.com/api/endpoint" # Replace with actual API endpoint

try:
    response = requests.get(url)
    response.raise_for_status()  # Raise an exception for bad status codes (4xx or 5xx)
    print(f"Status Code: {response.status_code}")
    print(f"Response Body: {response.json()}") # Assuming the response is JSON
except requests.exceptions.RequestException as e:
    print(f"Error making request: {e}")
```

### Data Submission Example in JavaScript

Source: https://apicenter.estaleiro.serpro.gov.br/documentacao/api-integra-contador/pt/solucoes/integra-sn/pgdasd/exemplos/retorno_consultar_extrato_do_das

This JavaScript code illustrates how to submit data to the API using the Fetch API. It's designed for front-end or Node.js environments and handles POST requests with JSON payloads. Ensure proper error handling for network or server issues.

```JavaScript
async function submitData(api_url, api_key, payload) {
    const response = await fetch(api_url, {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json',
            'Authorization': `Bearer ${api_key}`
        },
        body: JSON.stringify(payload)
    });

    if (!response.ok) {
        throw new Error(`HTTP error! status: ${response.status}`);
    }

    return response.json();
}

// Example usage:
// const apiUrl = "https://api.example.com/submit";
// const apiKey = "YOUR_API_KEY";
// const dataToSend = { name: "Example", value: 123 };
// submitData(apiUrl, apiKey, dataToSend)
//     .then(result => console.log('Success:', result))

### Basic API Request Handling (Java)

Source: https://apicenter.estaleiro.serpro.gov.br/documentacao/api-integra-contador/pt/solucoes/integra-sn/pgdasd/exemplos/retorno_gerar_das

This Java code illustrates a fundamental approach to handling API requests, likely within a web framework. It shows how to define a request method (e.g., GET), access request parameters, and return a simple string response. This forms the basis for many API endpoints.

```java
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ApiController {

    @GetMapping("/api/resource")
    public String getResource(@RequestParam(value = "name", defaultValue = "World") String name) {
        return "Hello, " + name + "!";
    }

    @GetMapping("/api/status")
    public String getStatus() {
        // In a real application, this would check system status
        return "API is operational";
    }
}
```

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public static String callApi() throws Exception {
        URL url = new URL(API_URL);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Accept", "application/json");

        int responseCode = conn.getResponseCode();
        if (responseCode != HttpURLConnection.HTTP_OK) {
            throw new RuntimeException("HTTP error code : " + responseCode);
        }

        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
