Mass-Delete-Action over API doesn't work because of scope

Hi all,

we're currently trying to mass delete 40000 deals from our CRM, that we have already put into a custom view. I'm not that used to the API, but I managed to authenticate by https://accounts.zoho.com/oauth/v2/token with Postman and going by the response I got the necessary scopes:
  1. {
    "access_token": "1000.x.x",
    "scope": "ZohoCRM.mass_delete.DELETE ZohoCRM.modules.ALL",
    "api_domain": "https://www.zohoapis.com",
    "token_type": "Bearer",
    "expires_in": 3600
    }
I tried making a GET-Request to https://www.zohoapis.com/crm/v7/Potentials/{id} to see if the token works and everything is fine. But when I try to make a POST-Request to https://www.zohoapis.com/crm/v7/Potentials/actions/mass_delete I get the following error:
  1. {
    "code": "OAUTH_SCOPE_MISMATCH",
    "details": {},
    "message": "invalid oauth scope to access this URL",
    "status": "error"
    }
What am I missing? Thank you for your help in advance.
