As per normal practice, you must configure the mode in which you are processing payments for each site that accepts credit card transactions. Since the configuration is per site, you can configure one site to process transactions with Connected Payments and another site to use Integrated Credit Mode (EDC).

To configure Connected Payments as the credit processing mode:

• In Web Admin, select Configuration > Site Set up > Sites.
• Select the site from the list and click Edit Site.
• Select the Submission Details tab.
• Select Connected Payments from the 'Credit Processing Mode' drop-down list.
  
• Click Update and exit the Sites function.
