Facebook API

Client Libraries
Client libraries will simplify the calls to the
platform by reducing the amount of code you
have to write.
If you don’t use a client library then will have to
do the following for each method call:
– Construct a signature
– Create and send a HTTP POST request
– Parse the XML result of the request
