About Billing Agreements

A billing agreement allows PayPal to withdraw funds from the buyer’s PayPal account

without requiring the buyer to log in to PayPal. Billing agreements are maintained by PayPal.

You must establish a billing agreement with a buyer if, for example, you and the buyer agree

that you will bill that buyer on a regularly scheduled basis such as monthly for a magazine

subscription. Before a billing agreement can take effect, the buyer must log in to PayPal once

to consent to it. With buyer consent, PayPal creates a billing agreement ID (BAID) to

represent the agreement. You pass the BAID in subsequent requests to bill the buyer. PayPal

withdraws funds without requiring the buyer to log in. A billing agreement is good until you or

the buyer cancels it.

A buyer may have multiple magazine subscriptions, each with a separate billing agreement. In

such cases, be sure to associate each transaction with the correct billing agreement.

About Billing Types

To specify how the buyer will be billed, you set the billing type in the call to Set Express

Checkout.

Table 2.1describes the values of this parameter:

Ways To Obtain a BAID

You can obtain a BAID whether or not the buyer logs in to PayPal to make a purchase. The

following sections describe how.
