# PayPal Billing Agreement

Consumers can use their PayPal accounts to make recurring subscription payments. Consumers have the option to choose to auto-renew or manually renew.  

## How to configure 

Configuring the PayPal Billing Agreement depends on whether you use [DigitalRiver.js with Elements](/commerce-api/payments/payments-solutions/digitalriver.js.md) or[ Drop-in payments](/commerce-api/payments/payments-solutions/drop-in.md).

## How it works

PayPal Billing Agreement uses a [redirect then submit (RTS) payment flow](/commerce-api/payments/building-your-workflows/flows-by-payment-type.md#redirect-then-submit-rts-payment-flow).
