You should (almost) always display the error traceback.  I suspect 
NameError: global 'SendRequest' not found.  You need 
Requests.SendRequest.  but...

If it were, then call the parameter 'cls', not 'self'.  But it is not a 
classmethod without @classmethod decorator.  but...

Does this need to send the class rather than instance object to the 
website?  If not, better to leave it an instance method and use 
self.SendRequest above.  If the request uses instance variables, then it 
*must* be an instance method!
