I am working on a Paypal integration that uses the Paypal server side API to create a purchase transaction. The response from paypal includes a redirect URL to which to redirect the customer to login/authorize the payment via their Paypal account. In this scenario I am not in control of what appears on the payment page since it is using Paypal's native payment UI. My question is, how do I enable Pay Later options, such as Pay in monthly installments? The Paypal documentation only seems to deal with the case where yo are building your own front-end. During my testing, when I logged into PayPal to authorize a payment the Apply for Credit button was displayed but not the Pay Later options. Can anyone briefly explain what criteria controls whether the customer sees the Pay Later option please? The Developer documentation seems to suggest that for merchants implementing their own checkout using the JS SDK they can control these buttons by passing the right parameters to the SDK. So is the display of these buttons managed purely from the state of a customer's account or can the merchant influence it as well?
