hi,

Iam integrating the Paypal pro for my site almost in final stage.For this i came to know they are two methods to integrate Paypal pro

1) With SDK installation
2) Without SDK installation (by using some NVP files)

Can any one know what is the exact difference Between the above two
Please clarify the above Thanks in advance

Hi,

SDK uses a SOAP (Simple Object Access Protocol ) object-oriented interface using data objects defined by the eBay Business Language (eBL) schema, where API requests and responses are sent as objects
via the SOAP protocol.


NVP(Name-Value Pair):

This also Uses a similar but different data dictionary to eBL

where API requests and responses are sent as simple strings via the HTTP protocol

You should use whichever method is easier for your programming style. The two interfaces

are described in more detail in the sections that follow, but the essential choice you have

to make is whether you want to form objects for your requests or compose long strings that

contain all request parameters as name=value pairs, with all pairs separated by ampersands.
