Hello,
When using Paypal Adaptive, the vendor must have a paypal email if they want to receive directly their money in their account.
Only your store need a Paypal Adaptive account.
For more details, please contact the Paypal support.
the customer would need to use paypal adaptive to pay for 1 item, and a different payment method for the other items?
The customer will pay an entire order using one single payment method.
You can't pay an order with several payment methods.
One order = One transaction.
So if the payment method do not feet to the entire order ; the method is not available.
Regards,
