can't add scopes to for my oauth token

[pado4821]

so i have this code thats works 

```python

encoded_credentials = base64.b64encode(f'{appid_}:{certid_}'.encode()).decode()

url = 'https://api.ebay.com/identity/v1/oauth2/token'

data = {

    'grant_type': 'client_credentials',

    'scope': 'https://api.ebay.com/oauth/api_scope',

}

print(data['scope'])

headers = {

    'Content-Type': 'application/x-www-form-urlencoded',

    'Authorization': f'Basic {encoded_credentials}'

}

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

print(response)

# Extract access token from response

token_ = response.json()['access_token']

```

but the problem is, when i try to add more scopes like https://api.ebay.com/oauth/api_scope/sell.marketing.readonly or https://api.ebay.com/oauth/api_scope/sell.inventory.readonly

i get the Response: 400 (bad request)

so i really don't know how to do that

eBay has two types of authorizations:

1.  Client credentials—gives your client application a token to request publicly available data from eBay. Client Credentials have limited use on the site, since the publicly available data has a limited scope.
    
2.  Authorization code—grants access to a specific user's private data via a user-approved token. An Authorization code has a broader array of scopes (varying degrees of limited access) to a user's private data.
    

https://developer.ebay.com/api-docs/static/oauth-scopes.html#Getting

A private user-based scope can not be applied to public Client credentials.

I believe multiple scopes are space delimited:

'scope':'value1 value2 value3'

But make sure that the scope you want to add is valid for the API call.
