So I see some docs saying that to test an API integration I should register for a sandbox account and put that info ( API Login ID, Transaction Key, and Client Key) in the code and test it that way.
Then I see right in my control panel in my live account, there is a Transaction Processing switch I can set to "test" and it says what I quote below. This seems to be WAY easier and I eliminate things like mistyping the server to connect to in my code, etc etc etc. It stands to reason that testing with live real code is always better than using a sandbox. The problem is, I cant seem to get anything other than a "[E00027] The transaction was unsuccessful."
I also can not find online documentation for using this method. Am I blind?
"Transaction Processing
While your account is in Test Mode you may:
- Confirm that you are successfully connected to the payment gateway
- Check that your API Login ID and Transaction Key are correct
- For more information, refer to Reference & User Guides
To process live transactions switch your account to LIVE"
