To avoid duplicating code that converts this ID into it's corresponding object, Drupal support autoloading for "named" wildcards.When a named wildcard is used, Drupal will check for a function with the same name as the wildcard, suffixed by is necessary to make the simple example above viewable at all, but it's hardly ideal, as it allows no control what so ever.Anyone that tries to visit /hello will be granted access.The easiest way to provide some measure of control, is to provide a I know that the docs say so, but when I tested in D7, that was not the case.An additional benefit that I’ll touch on briefly is access control.This hook allows you to specify what permissions a given path will require of the user.Enable the module, and go to /hello on your website. In the example below, this means the 0 will be turned into 'hello', as that's the first, and only, part of the URL. Often a URL argument will be the ID-number of something, such as an entity.

The Drupal community has contributed several modules for processing RESTful POSTs.

In particular, you may want to read about permissions, as the page above will be viewable by .
