Plone support for HTTP verbs.

Plone REST

Purpose allows you to use HTTP verbs such as GET, POST, PUT, DELETE, etc. in Plone.

REST stands for Representational State Transfer. It is a software architectural principle to create loosely coupled web APIs. provides the basic infrastructure that allows us to build RESTful endpoints in Plone.

The reason for separating this infrastructure into a separate package from the ‘main’ full Plone REST API is so you can create alternative endpoints tailored to specific usecases. A number of these specific endpoints are already in active use.

Audience is for experienced web developers who want to build their own HTTP/REST endpoints on top of Plone.

If you want to use a ready-made full RESTful Plone API, you should use plone.restapi. That package uses, and depends upon, this one.


  • Registering RESTful service endpoints for the following HTTP verbs:
    • GET
    • POST
    • PUT
    • DELETE
    • PATCH
  • Support for Dexterity and Archetypes-based content objects
  • Content negotiation (‘application/json’ is currently the only format supported).
  • Named services allows to register service endpoints for custom URLs

Registering RESTful Service Endpoints allows you to register HTTP verbs for Plone content with ZCML.

This is how you would register a PATCH request on Dexterity content:


You have to specify the HTTP verb (GET, POST, PUT, DELETE, HEAD, OPTIONS), the interface for the content objects and the factory class that actually returns the content.

The factory class needs to inherit from the ‘Service’ class and to implement a render method that returns a list or a dict:

from import Service

class Patch(Service):

    def render(self):
        return {'message': 'PATCH: Hello World!'}

The return value (list or dict) will be automatically transformed into JSON.

Content Negotiation

To access the service endpoint we just created we have to send a GET request to a Dexterity object by setting the ‘Accept’ header to ‘application/json’:

PATCH /Plone/doc1 HTTP/1.1
Host: localhost:8080
Accept: application/json

The server then will respond with ‘200 OK’:

HTTP/1.1 200 OK
Content-Type: application/json

  'message': 'PATCH: Hello World!'

You can try this out on the command line:

$ http --auth admin:admin PATCH localhost:8080/Plone/doc1 Accept:application/json


You have to install httpie (pip install httpie) to make this example work.

Here is a list of examples for all supported HTTP verbs:


$ http --auth admin:admin GET localhost:8080/Plone/doc1 Accept:application/json


$ http --auth admin:admin POST localhost:8080/Plone/doc1 Accept:application/json


$ http --auth admin:admin PUT localhost:8080/Plone/doc1 Accept:application/json


$ http --auth admin:admin DELETE localhost:8080/Plone/doc1 Accept:application/json


$ http --auth admin:admin PATCH localhost:8080/Plone/doc1 Accept:application/json


$ http --auth admin:admin OPTIONS localhost:8080/Plone/doc1 Accept:application/json

Named Services

Named services can be registered by providing a ‘name’ attribute in the service directive:


This registers a service endpoint accessible at the site root using the following request:

GET /Plone/search HTTP/1.1
Host: localhost:8080
Accept: application/json


Install by adding it to your buildout:

and then running “bin/buildout”
