Sandbox Private Key – (Test Mode) – The test mode checkbox must be enabled to use this field.
Clicking activate saves the settings and activates the gateway. It should now be available for customers to use when proceeding through the checkout.
If there is an API error being received, it should be checked that the correct Public & Private Keys have been input (not test keys) and are in the correct location and that Test Mode is disabled. Public keys start with sbpb_ (sandbox/test key) or lvpb_ (live key). It should also be checked that the keys being used are enabled for hosted payments. When looking at the key this hosted tag should be visible:
