How to create a user in the Moodle Rest WS using the Python Requests module?

I'm trying to create a user using the Moodle Webservices - Rest Server, but I'm stuck at the validation of the params :S My code is the following:

import requests

function = 'core_user_create_users'

url = 'http://localhost/webservice/rest/server.php?wstoken={0}&wsfunction={1}&moodlewsformat=json'.format(token,function)

user1 = {'email': '','firstname': 'firstname',
'lastname': 'lastname', 'createpassword': 1,
'username': 'username'}

Then, I try to post the data (two different ways):,data={'users': user1}),data={'users': [user1,]})

And moodle keeping return the error:

Only arrays accepted. The bad value is: \'username\'</DEBUGINFO>

In the documentation (available from the own moodle), its stated:

users (Obrigatório)

Estrutura geral

list of (
object {
username string //Username policy is defined in Moodle security config.
password string Opcional //Plain text password consisting of any characters
createpassword int Opcional //True if password should be created and mailed to user.
firstname string //The first name(s) of the user
lastname string //The family name of the user
email string //A valid and unique email address

)customfields Opcional //User custom fields (also known as user profil fields)
list of (

So, with this in mind, how can I create a Moodle user using python requests module? Whats wrong with the data that has been passed?


To use REST service in Moodle, parameters to function has to be formated in a flat dictionary. The structure of the arguments reflects in names of the keys. In your example, you have one argument courses which is a list. So keys of your dictionary will be courses[0]email, courses[0]firstname, ... for the first user, and courses[1]email, courses[1]firstname, ... for the second and so on

users = {'users[0]email': '',
         'users[0]firstname': 'firstname',
         'users[0]lastname': 'lastname', 
         'users[0]createpassword': 1,
         'users[0]username': 'username'},data=users)
