+Test Code - Apple Pay
+==============================================
+**Enables you to pass Apple Pay payment data to Authorize.Net.**
+
+Apple Pay support is available through the SDK using our new model 
+and code samples.
+
+###Create a Apple Pay Transaction
+Use this function to create an Authorize.Net payment transaction request 
+using Apple Pay Opaque data in place of card data. 
+
+**_DataDescriptor (Apple Pay Blob) is one-time use value._**
+
+A transaction of this type can be performed with the following code (JSP) :
