We are experiencing an inconsistent but frequent (approx one per day) issue where the response from the GetExpressCheckoutDetails call is missing the SHIPTONAME and PAYMENTREQUEST_0_SHIPTONAME array elements. All other SHIP... and PAYMENTREQUEST_0_SHIP... values are present. Here is a snippet of an example response:
[FIRSTNAME] => Redacted
[LASTNAME] => Redacted
[COUNTRYCODE] => AU
[SHIPTOSTREET] => 29 Redacted Road
[SHIPTOCITY] => Redacted Town
[SHIPTOSTATE] => New South Wales
[SHIPTOZIP] => 2321
[SHIPTOCOUNTRYCODE] => AU
...
[PAYMENTREQUEST_0_SHIPPINGAMT] => 9.05
[PAYMENTREQUEST_0_HANDLINGAMT] => 0.00
[PAYMENTREQUEST_0_TAXAMT] => 19.06
[PAYMENTREQUEST_0_SHIPTOSTREET] => 29 Redacted Road
[PAYMENTREQUEST_0_SHIPTOCITY] => Redacted Town
[PAYMENTREQUEST_0_SHIPTOSTATE] => New South Wales
[PAYMENTREQUEST_0_SHIPTOZIP] => 2321
[PAYMENTREQUEST_0_SHIPTOCOUNTRYCODE] => AU
The customer has supplied screenshots from their Paypal account to demonstrate that a shipping name (and address) was supplied. We can't reproduce this issue. Any pointer appreciated.
Apparently this is an issue with Paypal itself. We received the following response:
My name is REDACTED from PayPal merchant technical support. I understand that you are having a problem missing SHIPTONAME value and that causing you unable to supplied shipping information to your client. At the meantime, this issue was a well known issue at our end and we're still collecting data to resolve this issue.

We had the very same issue confirmed by Paypal. They said they rolled out a fix today for it. (07/07/2015 02:15 PM EST) " I have received word from our engineers that a correction has been made live for the bug that causes the SHIPTONAME to not be included. "
