Order approval settings are defined at the account level and apply to all contacts within the account. When you integrate with an external system, the order approval feature can be enabled or disabled only in the administration interface, not on the storefront.
To enable order approval and specify that an external system should determine if orders require approval:
Click the menu icon, then click Accounts.
Select the account to modify and click its Approvals tab.
If you are using multiple sites, select the name of the site. (Approvals are site-specific.)
Under Approval Settings, select Require Approval, then select Use external service to determine approval settings.
Click Save.
