11. The method of claim 10 , wherein user binding error information is returned in the event that that the platform parameters include a user session uniqueness identity in the Independent Software Vendor application and the service request message authentication fails.

12. The method of claim 10 , further comprising:

initiating a second service request message to a login address of the ISP upon receiving the user binding error information, wherein the second service request message includes as its platform-level parameters the Appkey associated with the application, a service name, a user session uniqueness identity in the Independent Software Vendor application and an address the Independent Software Vendor application to be redirected to upon passing user binding.

13. A service integration platform system for providing web services comprising:

an interface configured to receive a service request message that is initiated by a user of an application provided by an Independent Software Vendor (ISV), the service request message being implemented according to an Application Programming Interface (API) type and a plurality of platform-level parameters that conform to the API type, wherein:

the plurality of platform-level parameters comprise an Appkey associated with the application provided by the ISV;

the Appkey is a parameter issued to the application provided by the ISV and is not modifiable by the application provided by the ISV; and

the Appkey is a proof of identity that identifies the web services the application provided by the ISV is allowed to access; and one or more processors coupled to the interface, configured to:

determine a set of authentication checks that correspond to and that are appropriate for the API type, wherein:

the API type is one of a plurality of possible API types;

for each possible API type there is a corresponding set of authentication checks; and

at least some API types map to different sets of authentication checks;

perform authentication of the service request according to the set of authentication checks;

route the service request to a service address of an Internet Service Provider (ISP) in the event that the service request is authenticated, wherein the Internet Service Provider (ISP) is a provider of web services on the internet;

maintain a token list in a cache in the event that the platform parameters include service Internet Service Provider identity, the Appkey associated with the application and user session uniqueness identity in the Independent Software Vendor application; determine whether a token exists and is valid; and return user binding error information in the event that no token exists or the token is invalid;

wherein the API type has a corresponding service level comprising an authorized service type and the determined set of authentication checks includes a signature check and a timestamp check; and

wherein the platform-level parameters for the authorized service type further comprises a service name, a service request timestamp and a signature.

14. The system of claim 13 , wherein the API type has a corresponding service level comprising an anonymity access type and the set of determined authentication checks includes zero elements.
