Hi Edward, Apologies for the delay and thank you for the additional information. I could see that you are using production account credentials for you *oauth2_client_id* and *oauth2_client_secret* while using a test account customer ID as your *client_customer_id*. In order to make calls using your test account, you will need to fill these fields with test account information. As mentioned in my previous response, you will need to generate separate OAuth2 credentials for your test account while logged in to the email address you associated to your test account.
That being said, you may then use the below example to configure your yml file : :oauth2_client_id: [TEST-account] :oauth2_client_secret: [TEST-account-secret] :client_customer_id: [TEST-account-client-id] Let me know if this works.
