This page is to decide on a STANDARD list of CORE web service functions that we should support in Moodle (by XMLRPC, REST and SOAP with the option to plug in AMFPHP for Flash/Flex interfaces) as an API for those writing code to work against Moodle.
{{Template:Migrated|newDocId=/docs/apis/subsystems/external/}}
 
Please add new functions if there's functionality you want that isn't covered (we can refactor/whittle at the end).
 
The tracker bug for all this is here: MDL-12886
 
==add user==
[Feedback]
Speaking as someone who will be using this API to integrate with another line of business application I would recommend the following changes.
 
The add_user method should really be a 'SetUser' ie it will create the record if it does not exist or update it it if it does. The ID that is passed into the method would be *our* primary key which Moodle would use to recognise the user record within Moodle. We would not normally need to know anything about the Moodle primary key.
 
One option to make the web services maintainable is to accept XML as a parameter and not a structure or custom object. That way you can define an XSD which will define required\optional parameters. Equally if you include a version number you can change the XML to add new features without having to redefine the web service signature itself (and hence clients will not have to recompile their code). So you may receive a SetUser call with XML V1.0 and another with XML V2.0 on the same webservice but from two different clients supporting different versions of the API.
 
The method *must* accept an array of users - it's a little trickier to set this up in the client code but is much more scalable (if there's some good sample code then this is easier anyway). The latency (round trip time) with web service calls is high so you want to do as much as you can in a single call. We have a customer who wants us to deploy Moodle to 40,000 users - we're not going to do that using individual calls.
 
Would it be possible to expand on the existing web service work rather than produce something completely new? We're investing a lot of effort with these services and we wouldn't like to have to re-do that work.

I think we should require all data needed for a successful "first login" to Moodle without popping him out the profile page to fill in all missing required data. This may require extra inputs such as city, description ... (unsure of the full list depending of Moodle version ?).
Also password should be "required" if authentication method is "internal" .
 
INPUT:
    firstname
    lastname
    email
    idnumber
    login
    authentication method (optional , default= manual ?)
 
 
 
OPERATION:
    Adds a new user to the user database
 
OUTPUT:
    id or false
 
==delete user==
INPUT:
    idnumber  or
    email or
    id or
    login
 
OPERATION:
    User is marked as deleted
    All it's role assignments are destroyed
OUTPUT:
    true/false
 
==get user==
INPUT:
    idnumber  or
    email or
    id or
    login
 
OPERATION:
    user record with optional fields set (Moodle 1.8 and later) and maybe some fields filtered out (password,
    email if user said not to disclose it ...) depending of the identity of the "caller" (admin or the user himself)
 
OUTPUT:
    false  or user record
 
==add course==
INPUT:
    name
    shortname
    format (default topics)
    idnumber
 
OPERATION:
    Adds a new course to the course table
 
OUTPUT:
    id or false
 
 
==delete course==
INPUT:
    name OR
    shortname  OR
    idnumber OR
    id
 
OPERATION:
    Deletes a course from the course table
    What about associated ressources, roles ...
 
OUTPUT:
    true or false
 
 
==get course==
INPUT:
    id or  idnumber or shortname
 
OPERATION:
    fetch course record with some fields filtered out depending of the "caller" identity (admin, teacher, student ...)
OUTPUT:
    false  or course record
 
==enrol student to course==
[Feedback]
It's not clear what the difference is or significance of ID vs. idnumber is. Remember the web service developers will probably not be users of Moodle so it needs to be clear.
[/Feedback]
