Web Services¶
The web-service module offers a common interface for all web services:
XML-RPC
JSON-RPC
Business objects can also be accessed via the distributed object mechanism. They can all be modified via the client interface with contextual views.
Odoo is accessible through XML-RPC/JSON-RPC interfaces, for which libraries exist in many languages.
XML-RPC Library¶
The following example is a Python 3 program that interacts with an Odoo
server with the library xmlrpc.client
:
import xmlrpc.client
root = 'http://%s:%d/xmlrpc/' % (HOST, PORT)
uid = xmlrpc.client.ServerProxy(root + 'common').login(DB, USER, PASS)
print("Logged in as %s (uid: %d)" % (USER, uid))
# Create a new note
sock = xmlrpc.client.ServerProxy(root + 'object')
args = {
'color' : 8,
'memo' : 'This is a note',
'create_uid': uid,
}
note_id = sock.execute(DB, uid, PASS, 'note.note', 'create', args)
Exercise
Add a new service to the client
Write a Python program able to send XML-RPC requests to a PC running Odoo (yours, or your instructor’s). This program should display all the sessions, and their corresponding number of seats. It should also create a new session for one of the courses.

JSON-RPC Library¶
The following example is a Python 3 program that interacts with an Odoo server
with the standard Python libraries urllib.request
and json
. This
example assumes the Productivity app (note
) is installed:
import json
import random
import urllib.request
HOST = 'localhost'
PORT = 8069
DB = 'openacademy'
USER = 'admin'
PASS = 'admin'
def json_rpc(url, method, params):
data = {
"jsonrpc": "2.0",
"method": method,
"params": params,
"id": random.randint(0, 1000000000),
}
req = urllib.request.Request(url=url, data=json.dumps(data).encode(), headers={
"Content-Type":"application/json",
})
reply = json.loads(urllib.request.urlopen(req).read().decode('UTF-8'))
if reply.get("error"):
raise Exception(reply["error"])
return reply["result"]
def call(url, service, method, *args):
return json_rpc(url, "call", {"service": service, "method": method, "args": args})
# log in the given database
url = "http://%s:%s/jsonrpc" % (HOST, PORT)
uid = call(url, "common", "login", DB, USER, PASS)
# create a new note
args = {
'color': 8,
'memo': 'This is another note',
'create_uid': uid,
}
note_id = call(url, "object", "execute", DB, uid, PASS, 'note.note', 'create', args)
Examples can be easily adapted from XML-RPC to JSON-RPC.
Nota
There are a number of high-level APIs in various languages to access Odoo systems without explicitly going through XML-RPC or JSON-RPC, such as:
