Hi, I’m trying to use the cards api but it gives me an error, I’m using access\_token authentication:  
curl --location --request GET ‘[https://api.hubapi.com/crm/v3/extensions/cards/{appid}](https://api.hubapi.com/crm/v3/extensions/cards/%7Bappid%7D)’ \  
--header ‘Authorization: Bearer {access\_token}’

I am getting the following error:  
Authentication credentials not found. This API supports both API Key and OAuth 2.0 authentication and you can find more details at [Accounts Dashboard | HubSpot](https://developers.hubspot.com/docs/methods/auth/oauth-overview)
