Communicating Roblox's Inventory API with python?

[snippsat]

Requests is what you should use in Python for this.
There usually some documentation for an API.
Not looking at doc just using you address can build a requests like this.

import requests

params = {
    'assetTypes': 'Animation',
    'limit': '10',
    'sortOrder': 'Asc',
}

response = requests.get('https://inventory.roblox.com/v2/users/654357401/inventory', params=params)

So if look at response get 403 and the json back that's not authorized,you may have a API key or the requests may now be wrong.

>>> response.status_code
403
>>> 
>>> json_data = response.json()
>>> json_data
{'errors': [{'code': 4,
             'message': "You are not authorized to view this user's inventory.",
             'userFacingMessage': 'Something went wrong'}]}
>>> 
>>> json_data['errors'][0]['message']
"You are not authorized to view this user's inventory."
