* As such, we need to loop through all the payment info in the response.
*
* The library helps us do this using the GetExpressCheckoutPaymentInfo() method. We'll
* load our $payments_info using that method, and then loop through the results to pull
* out our details for the transaction.
*
* Again, in this case we are you only working with a single payment, but we'll still
* loop through the results accordingly.
*
* Here, we're only pulling out the PayPal transaction ID and fee amount, but you may
* refer to the API reference for all the additional parameters you have available at
* this point.
