The XML Web Services API

Any quality software product comes with a comprehensive API for deep integration, and PaperCut is no exception! Our industry standard Web Services API allows you to integrate with PaperCut with a programming language of your choice. Web Services data is transmitted over standard HTTP or HTTPS and uses standardized XML mark-up.

There are two main Web Services implementations used for Remote Procedure Call (RPC):

PaperCut MF uses XML-RPC. XML-RPC is a lightweight web services implementation and has good support for all major programming and scripting languages such as C#, Java, Visual Basic, Perl, Ruby and Python.

API methods are accessed by the URL http://[server_name]:9191/rpc/api/xmlrpc, or https://[server_name]:9192/rpc/api/xmlrpc for secure connections. You will also need to ensure you are making your API call from an authorized address. More information on API usage is provided below.

MethodDescription

api.isUserExists

Test to see if a user exists in the system/database.

api.getUserAccountBalance

Get the user's current account balance.

api.getUserProperty

Gets a user property. Properties include the user's full name, department, email, notes, office and restriction status among others.

api.getUserProperties

Get multiple user properties at once. Properties include the user's full name, department, email, notes, office and restriction status among others.

api.setUserProperty

Sets a user property. Properties include the user's full name, department, email, notes, office, password (for internal users) and restriction status among others.

api.setUserProperties

Set multiple user properties at once. Properties include the user's full name, department, email, notes, office, password (for internal users) and restriction status among others.

api.adjustUserAccountBalance

Adjust a user's account balance by an adjustment amount. An adjustment may be positive (add to the user's account) or negative (subtract from the account).

api.adjustUserAccountBalanceIfAvailable

Adjust a user's account balance if there is enough credit available.

api.adjustUserAccountBalanceIfAvailableLeaveRemaining

Adjust a user's account balance if there is enough credit available to leave the given amount available in the account.

api.adjustUserAccountBalanceByGroup

Adjust the account balance for all users in a group by an adjustment amount. An adjustment may be positive (add to the user's account) or negative (subtract from the account).

api.adjustUserAccountBalanceByGroupUpTo

Adjust the account balance for all users in a group by an adjustment amount, but not above the given limit. An adjustment may be positive (add to the user's account) or negative (subtract from the account).

api.setUserAccountBalance

Set the balance on a user's account to a set value. This is conducted as a transaction.

api.setUserAccountBalanceByGroup

Set the balance for each member of a group to the given value.

api.resetUserCounts

Reset the counts (pages and job counts) associated with a user account.

api.reapplyInitialUserSettings

Re-applies initial settings on the user. Initial user settings are based on group membership.

api.disablePrintingForUser

Disable printing for a user for selected period of time.

api.addNewUser

Triggers the process of adding a new user account defined by a given username. Assuming the user exists in the OS/Network/Domain user directory, the account will be created with the correct initial settings as defined by the rules set up in the admin interface under the Group's section. Calling this method is equivalent to triggering the "new user" event when a new user performs printing for the first time.

api.renameUserAccount

Rename a user account. Useful when the user has been renamed in the domain / directory, so that usage history can be maintained for the new username. This should be performed in conjunction with a rename of the user in the domain / user directory, as all future usage and authentication will need to use the new username.

api.getUserGroups

Retrieves all groups a single user is a member of.

api.deleteExistingUser

Delete/remove an existing user from the user list. Use this method with care. Calling this will perminently delete the user account from the user list (print and transaction history records remain).

api.addNewInternalUser

Creates and sets up a new internal user account.

In PaperCut MF all internal usernames must only contain characters that can be printed (e.g. not newline) and must not contain /, \ or @.

api.lookUpUserNameByIDNo

Looks up the user with the given user id number and returns their user name. If no match was found an empty string is returned.

api.lookUpUserNameByCardNo

Looks up the user with the given user card number and returns their user name. If no match was found an empty string is returned.

api.addAdminAccessUser

Add a user as an admin with default admin rights.

api.removeAdminAccessUser

When retrieving a list of all user accounts, the recommended page size / limit is 1000. Batching in groups of 1000 ensures efficient transfer and processing.

E.g.:

    listUserAccounts("authToken", 0, 1000) - 
    returns users 0 through 999
    listUserAccounts("authToken", 1000, 1000) -

api.listUserSharedAccounts

List all shared accounts the user has access to (sorted by account name), starting at offset and ending at limit. This can be used to enumerate the accounts in 'pages'. When retrieving a list of all accounts, the recommended page size / limit is 1000. Batching in groups of 1000 ensures efficient transfer and processing.

You may optionally specify TRUE to list accounts even if the user is currently not configured to charge to a shared account.

E.g.:

    listUserSharedAccounts("authToken", "username", 0, 1000) - 
    returns shared accounts 0 through 999

Table A.1. XML Web Services Methods

Web Services Example Code

The best way to demonstrate how to use the Web Services interface is using example code. PaperCut MF ships with example code for Java, C#, Python and Ruby located in:

    [app-path]/server/examples/webservices/
                

The C# and Java examples also include a full documented Proxy class - a proxy is a common program design pattern. The Proxy wraps and exposes the Web Services methods as standard methods. The setup and use of the underlying XML-RPC library is all handled in the proxy class meaning you can just focus on calling the methods.

Please see the README.txt files in the examples directories for more information. The Java example includes full JavaDoc style documentation under

                [app-path]/server/examples/webservices/java/docs/api

.

Developers using other languages such as Perl or Python will need to use an XML-RPC library to call the methods directly. All methods are exposed via the URL http://[server_name]:9191/rpc/api/xmlrpc.

Tip

All the XML Web Services commands are also accessible via the server-command program. An alternative to using a full programming environment to automate PaperCut MF via Web Services is to use the server-command program to call the commands via a script such as a batch file or shell script. This may be a simpler solution for common automation tasks such as scheduling a User/Group synchronization each night.

More information on the server-command program can be found in the section called “Server Commands (server-command)”.

Tip

Programmers often report that they get an error message "ERROR: java.lang.NoSuchMethodException:" and this is frequently because they are calling the API method with the wrong number or type of parameters. Consult the Javadoc API documentation (see above) for information on what parameters you need to use.

Security

The Web Services API's provide full access to the system's internals and hence need to be secured. PaperCut MF secures access using two security layers:

  1. IP address level security

  2. Authentication tokens - required for each method call

The IP address level security is used to control which systems, denoted by IP address, are allowed to connect to the server and call the API's. By default this is restricted to localhost (127.0.0.1) only. If the program/script making use of the API's resides on another system, then this system's IP address will need to be added to the list of approved addresses under OptionsAdvancedAllowed XML Web Services callers.

The first argument to all method calls is an authentication token (authToken). In the default setup the authentication token is the built-in admin user's password (This is password defined for the admin during the initial configuration wizard). Optionally an alternative web service authentication token may be defined via configuration - see below. This token must be supplied with all method calls.

To specify an alternative web service authentication token, to avoid the need to use/share the built-in admin user's password:

  1. Login to the system.

  2. Navigate to the Options section.

  3. Click on the Config editor link in the list of actions.

  4. Find the auth.webservices.auth-token config setting.

  5. Enter a new value that will be the new web services authentication token.

  6. Press the Update button to the right to apply the change.

  7. This authentication token can now be used in addition to the built-in admin user's password.
