With the initial setup complete it is time to move onto setting up your Payment Providers. You can navigate using the search.
As soon as you open the page there will already be data setup, the Get Default Configuration you ran earlier in the setup will create the Payment Providers below. Each Payment Provider must have a Payment Provider Account, you can navigate to the account for each Payment Provider by selecting one and clicking the Accounts button in the ribbon.
NB: The Payment Provider Accounts need to be created for each payment provider.
