#summary HTTP access to prosody’s storage mechanism
= Introduction =
This module gives HTTP access to prosody’s storage mechanism. It uses normal HTTP verbs and [http://tools.ietf.org/html/rfc2617 Basic HTTP authentication], so you could call it RESTful if you like buzzwords.
= Syntax =
To Fetch data, issue a normal GET request
{{{
GET /data[/<host>/<user>]/<store>[/<format>] HTTP/1.1
Authorization: <base64(authzid:password)>
-- OR --
PUT|POST /data[/<host>/<user>]/<store> HTTP/1.1
Content-Type: text/x-lua | application/json
<data>
}}}
These map to `datamanager.method(user, host, store, data)`, where choice of `method` and its parameters are explained below.
== Verbs ==
||*Verb*||*Meaning* ||*datamanager method* ||
||`GET` || Just fetch data || `load()` or `list_load()` ||
||`PUT` || Replace all data in the store || `store() ||
||`POST`|| Append item to the store || `list_append()` ||
Note: In a `GET` request, if `load()` returns `nil`, `list_load()` will be tried instead.
== Fields ==
||*Field*||*Description*||*Default*||
||`host`||Which virtual host to access||Required. If not set in the path, the domain-part of the authzid is used.||
||`user`||Which users storage to access||Required. If not set in the path, uses the node part of the authzid.||
||`store`||Which storage to access.||Required.||
||`format`||Which format to serialize to. `json` and `lua` are supported. When uploading data, the `Content-Type` header is used.||`json`||
||`data`||The actual data to upload in a `PUT` or `POST` request.||`nil`||
Note: Only admins can change data for users other than themselves.
== Example usage ==

{"password":"secr1t"}

}}}
