These keys can be used when implementing hook_service

#method

(required) Public method name. If it contains a dot, the part before the dot is assumed to be the namespace, the other part: function name.

#callback

(required) Function name of the method in your code.

#access callback

Which function does some access control? If not defined, the user_access function will be used.

#access arguments

Arguments for the '#access callback' function. If not defined access arguments will be ignored.

#file

Which file defines the '#callback' function? If node_service.inc, then write array('file' => 'inc', 'module' => 'node_service'). This is not required if you define your methods in the .module file. Array keys are 'file', 'module', and 'file name', following the module_load_include API.

#key

Does this method require a key? Default: TRUE

#auth

Does this method require a session id? Default: TRUE

#args

The arguments of the callback function. For each argument, you can define the following keys:

#name

Argument name

#type

Argument data type. Choose one of these: boolean, double, int, string, array, struct, date or base64, see xmlrpc_value_calculate_type(). Ps: you can use 'big' to get a textarea in services admin browser but it really is data type 'string'.

#description

Help text.

#optional

Is this argument required? Default: FALSE

#signed

Include this argument when computing the hash? Default: FALSE

#title

Label used with this argument's form element on the services admin browse form of this method. Default: '#name'.

#return

#help
