There is a configuration change that might be required if you are running PHP 5.6: the always_populate_raw_post_data setting. If you try to enable the RESTful Web Services module without changing the default setting, you will see the following error message on installation:

The always_populate_raw_post_data PHP setting should be set to -1 in PHP version 5.6. Please check the PHP manual for information on how to correct this. (Currently using always_populate_raw_post_data PHP setting version not set to -1.)
