Yes! PayPal offers two different ways to pay.  They offer paying via a PayPal account as well as a credit card processing service.  In both cases you should send us the $payment_gateway value $paypal in your $payment_method object.

If they are paying via a PayPal account set the $payment_type to $third_party_processor, and in the case of credit card processing set the $payment_type to $credit_card.

We have other supported subfields for PayPal including:

• $paypal_payer_id
• $paypal_payer_email
• $paypal_payer_status
• $paypal_address_status
• $paypal_protection_eligibility
• $paypal_payment_status

We encourage you to send as many of these as possible. For more information on the Payment Method object, see our Events API documentation.
