### List SKU Inventory Levels - Python

Source: https://docs.shipstation.com/openapi/inventory/updateskustocklevels

A Python script demonstrating how to query SKU inventory levels from the ShipStation API v2. This example uses the `requests` library to make a GET request, passing necessary headers including the API key and query parameters for filtering and grouping inventory data.

```python
import requests

def list_inventory(api_key, params):
    base_url = "https://api.shipstation.com/v2/inventory"
    headers = {
        "Authorization": f"ApiKey {api_key}"
    }
    try:
        response = requests.get(base_url, headers=headers, params=params)
        response.raise_for_status()  # Raise an exception for bad status codes
        data = response.json()
        print(data)
        return data
    except requests.exceptions.RequestException as e:
        print(f"Error fetching inventory: {e}")
        return None

# Example Usage:
