This page describes the API that Sugar Network clients use to interact with Sugar Network server. See also a guide to basic Sugar Network concepts and its twin page from technical point of view. Besides, visit the introduction page.

Overview

To better understand this API, see technical explanation of the conceptual level and objects model in particular.

The API operates with resources that are collections of objects. All objects are identified by global unique identifiers, GUIDs. Resources might support common actions. While processing requests, server might generate events. There are common events that all resources might generate.

The API is RESTful and being served via HTTP(S) using JSON notation. The common RESTful request url format is: 

http[s]://<SERVER>/<RESOURCE>[/<GUID|ACTION>[/<ACTION>]][?<ARG>=<>..]

When:

  • RESOURCE value is one of existing resources;
  • GUID, the RESOURCE's particular object;
  • ACTION and a set of ARGs depend on particular RESOURCE.

Besides, particular request can send and receive data in JSON notation. If request processing was failed, the reply is a JSON directory that contains error key with error message.

Actions

Actions might be restricted for particular resource, see the corresponding section for detailed information. 

POST /<RESOURCE>

Create new RESOURCE object.

Sends:

Resource properties.

Receives:

  • guid, str
    globally unique identifier that specifies created object;
PUT /<RESOURCE>/<GUID>

Modify the specified RESOURCE object. By default, might be called only by RESOURCE creator.

Sends:

Keys that need to be modified.
DELETE /<RESOURCE>/<GUID>

Delete the specified RESOURCE object. The real destroying won't happen, the object will be hidden. The garbage collection of hidden objects will be processed by Network administrators. By default, might be called only by RESOURCE creator. 

GET /<RESOURCE>?offset=<INTEGER>&limit=<INTEGER>[&query=<STRING>][&reply=<PROP>[,..]][&order_by=[+|-]<PROP>][&<QUERY_PROP>=<VALUE>[&...]]

Find RESOURCE objects.

Where:

  • offset, int
    start index to return entries from;
  • limit, int
    do not return more then specified value;
  • query, str
    search request in Xapian notation with the following additions:
    • if property is boolean, integer or datetime, it supports searching by ranges: <PROP>:[<START>]..[<END>];
    • the statement <PROP>:=["]<VALUE>["] means (<THE-REST_QUERY>) AND <EXACT-PROP-SEARCH> with searching PROP for exact VALUE; it is different to regular <PROP>:<VALUE> where VALUE might be a substring of exact PROP value;
  • QUERY_PROP, str
    supplement query with filtering by property value, the resulting query string will be QUERY_PROP=VALUE AND (query);
  • reply, str
    coma separated list of RESOURCE properties to return; by default, return only guid property;
  • order_by, str
    property to sort the resulting list by; if starts with the -, the order is descending, otherwise it is ascending.

Sends:

  • A dictionary with RESOURCE's properties to restrict the resulting list.

Receives:

  • An array of dictionaries with RESOURCE properties, dictionaries contain at least guid property.
GET /<RESOURCE>/<GUID>

Return RESOURCE properties the of particular object.

Receives:

  • A dictionary with RESOURCE properties that contains at least guid property.

Receives:

Rendered Wiki with text/html MIME type.
PUT /<RESOURCE>/<GUID>/wikitext

Put new content for Wiki page. Only object creator can use it.

Sends:

Wiki sources with text/plain MIME type.

Events:

type: update
