I am trying to set up a Sandbox account for our client's Magento 2.3 site on their staging environment. We are using the
Authorize.net payment method, and we keep receiving an error when we place test orders. We have regenerated all of the credentials, including the transaction, signature, and client public keys, but that has not helped. The error message we are receiving is “An error occurred during processing. Please try again.” The exact response string is:
{"messages":{"resultCode":"Error","message":[{"code":"E00001","text":"An error occurred during processing. Please try again."}]}}
Are there any additional steps we need to take to be able to successfully place test orders through our sandbox account?
