Adyen Error message: "010- Not allowed"

This article covers: Why would we get this Adyen payment method error - "010- Not allowed" while testing the card for creating the Customer/ Subscription?

Solution:

This response indicates that you are missing the right permissions while doing the operation. This means most likely your API credentials (web service user) (eg. ws@Company.[YourCompanyAccount]) do not have the right roles for the request you are trying to make.

You could refer to the documentation here to understand the issue in detail and the steps to resolve this. You will need to reach out to Adyen support so that they can enable this role (Checkout Webservice role) in case you don't have this enabled.
