Integrate your system with Möbius API

The Möbius Web Services API allows users to query Möbius data from custom-built online systems (such as course management systems), and provide access points to several parts of Möbius:

Endpoint services: ask for XML-formatted requests and return XML-formatted responses for connection to Möbius, and data retrieval and manipulation from Möbius. Requests are sent as a body of standard HTTP POST requests. Each XML response includes a standard part that provides information about the status of the request processing.
Launcher services: ask for regular HTTP requests with request parameters specified in name-value pairs and do not return any readable responses. They serve to launch corresponding sections of Möbius in the current browser for the user to further interact with.

The Möbius Web Services API also supports automatic grade pushing to the external system from Möbius.

To use Möbius Web Services, the following parameters are required and are stored by DigitalEd as part of hosting your Möbius site:

Name	Required	Type	Description
WS_PASSWORD	YES	String	Shared password that will be used to sign request data. The receiving side should know the password and use it to ensure that the request comes from a valid sender.

Connection test

This service allows testing of the API connection and works as an echo service, returning the value sent in the request.

Ping site

Purpose: Pings the Möbius site.

Name	Required	Type	Description
value	YES	String	Any string - it will be echoed back in the response.
timestamp	YES	Long	Current time in milliseconds (Java style).

</Response>

Name	Type	Description
value	String	String passed to the service in the request.

Connect or disconnect user session

These services provide a means for opening and closing a user session in Möbius.

The "Connect" service opens a user session, creates the user account (if it doesn't already exist), and updates the user account with the information provided.

If the classId value isn't set to an existing class, the user session can call services not related to any specific class (list classes, create new classes). This is analogous to a user logging in and staying on the System Homepage.

If the classId value is set to an existing class, then this "Connect to a class" request enters the user into the Möbius class specified in the request; the user session can call services related to the specific class (list assignments, list grades). This is analogous to a user logging in, and going to the Class Homepage for the specified class.

The "Disconnect" service closes the user session that was previously opened by the "Connect" service.

Connect (login)

Purpose: Creates a user session with the specified user and privileges.

Launcher services

Launcher services work as endpoints to Möbius with automatic login for the user.

They allow the starting of Möbius activities as well as direct navigation to the System Homepage, Class Homepage, Proctor Tools, or Gradebook pages.

Each launcher request includes a wsActionID parameter that identifies the type of the launcher service, as well as a set of parameters that match fields from either the “Connect” or “Connect to a Class” calls.

POST versus GET request methods

The following sections assume that the POST request method is being used. If you plan to use the GET request method, you’ll need to:

URL-encode all of the parameters.
Use "launcher.do" in the Relative URL instead of just "launcher".
End the entire URL with an ampersand (&).

Note that GET requests may be more convenient to use, but they inherently provide less security than POST requests. GET requests expose all request parameters (even if they run over SSL) and make it easier for a malicious third party to intercept, modify, and resubmit the request. The valid signature does not guarantee that the content of the request wasn't tampered with.

Grade pushing service

When a Möbius assignment is launched by a student from the external system, grade pushing means that immediately after grading is completed in Möbius, the grade for that student will be sent back to the external system.

The grade information is sent in the body of a regular POST request to a specified endpoint on the external system. The Möbius grade pushing service expects feedback from the external system to confirm the status of the operation.

In order for this service to function, you'll need to provide details of the external system to DigitalEd, so that the following properties can be set for your Möbius site:

Name	Required	Example	Description
WS_SERVER_URI	YES	https://yourserver.com:433	The URL of the external system that will receive the grade data.
WS_GRADE_URI	YES	grade/import/grade_receiver	A URI (relative to WS_SERVER) for the endpoint of the external system that will process the grade data.
WS_PASSWORD	YES	Any string	Shared password with which Möbius will sign the grade push request. The receiving side should know the password and use it to validate the request.
GRADE_EXPORT_TYPE	YES	BEST	Set to BEST, AVERAGE, or LAST to indicate which grade will be sent where the student has multiple grades for the given assignment.
WS_EMAIL_ON_ERROR	NO	Boolean (true or false)	Specify if an email notification will be sent when grade pushing fails.
WS_EMAILS	NO	admin@myuni.edu	Email address(es) where the notification will be sent when grade pushing fails. If none are provided, the class instructor's email address will be used by default.

Grade push details

Purpose: Pushes a grade from Möbius to the external system
