# Routing Data Requests

> This endpoint returns routing data requests.

### Body

# POST Endpoint Usage

This documentation provides detailed instructions on using the `POST` endpoint to submit routing data requests with our API.

## Prerequisites

Ensure Node.js is installed and you have Axios and the filesystem module:

```bash theme={null}
npm install axios fs
```

```js theme={null}
const axios = require('axios');
const fs = require('fs'); // Import filesystem module for file handling

async function fetchRoute(coordinates) {
  const apiKey = 'YOUR_API_KEY_HERE'; // Ensure you replace this with your actual API key
  const apiUrl = 'https://www.usepathway.dev/api/routing';

  const payload = {
    data: {
      coordinates: coordinates
    }
  };

  try {
    const response = await axios.post(apiUrl, payload, {
      headers: {
        'x-api-key': apiKey,
        'Content-Type': 'application/json',
      },
    });

    // Log and save detailed route information
    console.log('Received Routing Data:', response.data);
    response.data.routes.forEach((route, index) => {
      const geometryData = `Route ${index + 1} Geometry:\n${route.geometry}\n`;
      fs.writeFile(`route${index + 1}_geometry.txt`, geometryData, (err) => {
        if (err) throw err;
        console.log(`Geometry for Route ${index + 1 has been saved in a separate file.`);
      });
    });

  } catch (error) {
    console.error('Error:', error.response ? error.response.data : error.message);
  }
}

// Sample coordinates for route calculation
const coordinates = [
    [-122.4194, 37.7749], // San Francisco, CA
    [-118.2437, 34.0522], // Los Angeles, CA
];

fetchRoute(coordinates);
```

## JSON Response Structure

Here is an example of the JSON response structure after a successful POST request:

```bash theme={null}
{
  "code": "Ok",
  "routes": [
    {
      "geometry": "...",
      "legs": [...],
      "weight_name": "routability",
      "weight": 633.6,
      "duration": 630.7,
      "distance": 4732.2
    }
  ],
  "waypoints": [
    {
      "hint": "...",
      "distance": 4.231521214,
      "name": "Friedrichstraße",
      "location": [13.388798, 52.517033]
    },
    {
      "hint": "...",
      "distance": 2.795148358,
      "name": "Torstraße",
      "location": [13.39763, 52.529432]
    }
  ]
}
```
