Moneydance enables advanced users to develop extensions using a free
Extension Developer’s Kit that is easy to download and use. The developer’s kit
includes sample code, the necessary libraries to package and sign your
extension, and an ANT build file for compiling, packaging, and signing your
The Moneydance API that can be used from your extension code is available here:

An additional resource is the Extension Development
section of The Infinite Kind’s support forum. This forum can be used for questions about writing extensions, scripts, and code
that works with Moneydance.
Some of the facts to consider when developing Moneydance extensions:
- Each extension is self-contained in a single MXT file.
A correctly packaged extension is completely contained within an MXT file.
Moneydance can add extensions from MXT files stored at moneydance.com or directly
from the users hard drive. The Extension Developer’s Kit can be used to package
and sign your extension.
- Every extension includes a digital signature that is verified each time the extension is loaded
Every extension must be audited and signed by The Infinite Kind before users will be able
to load it into Moneydance. Extensions with invalid or missing signatures will generate an
error and will not be loaded unless the user forces the extension to load.
- Extensions can access the financial data objects within Moneydance.
Extensions have full access to the financial data in Moneydance. They can analyze, edit,
and modify the data. Extensions are also notified when application events happen such
as opening or closing a file, or modifying a transaction.
- Extensions can integrate with the Moneydance user interface to provide a seamless user experience.
Extensions can register “features” with the program which create icons on the main toolbar.
When the user clicks a toolbar icon, the associated extension is invoked. Extensions can also be
notified when the user opens or closes a file, or whenever any part of the data model is modified.
In future versions of Moneydance, extensions will be able to register interface components that
can be displayed on the Moneydance startup screen.
Extensions can also invoke other features and extensions in Moneydance using Uniform Resource
Identifiers (URIs) that identify different resources and services. For example, an extension
could call the following to display a net worth report:
or the following to display the edit-reminders window:
The URI concept provides the ability to invoke almost any function that is available
within Moneydance while maintaining a loose coupling between extensions and the application.
For a list of URIs that can be invoked from within Moneydance see our URI Scheme page.
In addition, extensions can add an item to the home/start page. Basically, to do this you can call:
where ‘view’ is an object implementing the
Extensions can receive notifications when certain events occur. To receive these event notifications, override the following method:
public void handleEvent(String eventURI)
New events can always be registered. Some of the events that are fired now include:
- md:file:opening (file will be opened)
- md:account:root (homepage was selected)
- md:file:opened (file was opened)
- md:file:closing (file will be closed)
- md:account:select (acount was selected)
- md:viewreminders (reminders were selected/viewed)
