How can I require a buyer's phone number with Paypal Express Checkout?

Question

I\'m working on Express Checkout integration, and have everything working without any technical problems. The only issue is that we need to have the buyer\'s phone number.

Answer 1

If anyone is still having trouble getting the phone number: even after I made the prefs change suggested above I couldn't see it in the payment response, but it IS available via a request to /v1/payments/payment/PAYMENT_ID via the REST API. Payer-PayerInfo->Phone.
