Content-Type: multipart/form-data

Reference: https://docs.cable.tech/v-1-0/api-reference/customer-data-api/upload/upload-csv

## Authentication

- `x-api-key` header (required) — API Key authentication via header

### Body (multipart/form-data)

This endpoint expects a multipart form with multiple files.

- `filename` (files, optional)

## Response

### 200

Operation success

## Examples

**Request**

```

**SDK Code**

```python
import requests

url = "https://api.cable.tech/v1/upload/csv"

files = { "filename": "open('network_logs_may.csv', 'rb')" }
headers = {"x-api-key": "<apiKey>"}

response = requests.post(url, files=files, headers=headers)

print(response.json())
```

```javascript
const url = 'https://api.cable.tech/v1/upload/csv';
const form = new FormData();
form.append('filename', 'customer_data_2024-06.csv');
form.append('filename', 'network_logs_may.csv');

const options = {method: 'POST', headers: {'x-api-key': '<apiKey>'}};

options.body = form;

try {
