Plugin Framework > Getting Started

What is it?

The Plugin Framework is how you can extend Banno’s user interface.

With the Plugin Framework, you can build your own custom cards that will appear in your user’s Dashboard in Banno for quick information and fast action. These custom cards are referred to as “plugins”.

Download the Mobile Apps for the Garden demo institution

The Banno Mobile apps for the Garden demo institution are available on Google Play and the App Store.

What is its purpose?

Building custom plugins is how you can bring the best of fintech directly to your customer’s fingertips.

How do I use it?

These are some of the things you should know about the Plugin Framework.

Have you read the guide on Designing and Developing Plugins?

User interface

Plugins are web applications (i.e. HTML + CSS + JavaScript) that can be configured to display as cards (i.e. Card Face) in a user’s Dashboard in Banno Online & Mobile.

Plugins should be designed to be responsive and adapt to a variety of screen sizes to accommodate a great user experience for both Banno Online and Banno Mobile users.

Plugins use a Card Face to show ‘summary’ or ‘overview’ kinds of information. Plugins can also be configured with a primary action button to navigate the user to an Expanded View.

  • The Expanded View should be used when deeper user interaction and more screen real estate is necessary.

  • An alternative to configuring a primary action button is to use the @jack-henry/banno-plugin-framework-bridge JavaScript module to route click events (such as triggering the Expanded View). See the @jack-henry/banno-plugin-framework-bridge topic for details.

Plugins should work in all browsers and operating systems supported by Banno.

Have you read the User Interface topic?


Plugins are hosted in your own public-facing web server and are requested by Banno’s UI when needed.

Have you read the Hosting topic?


Web browsers have become increasingly restrictive on cross-site cookie tracking, which affects how cookies can be used within a plugin.

Plugins that want authenticated information about the user will need to handle an authentication request and exchange with Banno using our Authentication Framework.

Have you read the Authentication topic?


The Plugin Framework is specifically designed to protect the security of the user and protect the user experience.

While plugins are based on standard HTML, CSS and JavaScript, the full complexity of a modern browser is not supported.

Have you read the Restrictions topic?

External applications

Plugins require a set of credentials to be configured as an External Application in the Banno People app.

The back office administrator at your financial institution can do this for you in the External applications section of Banno People.

Have you read the External Applications topic?

Dashboard configuration

Plugins must be configured in the Banno People app.

The back office administrator at your financial institution can do this for you in the Dashboard configuration section of Banno People.

Have you read the Configuration topic?

How have others used it?

Launching your project

We have resources which can help your project on its way towards launching and “going live” at a financial institution.

Review process

A frequently asked question:

Is there a review process for fintechs before being able to integrate with a financial institution?

No, there is no review process required, by Jack Henry, for a fintech to integrate with a financial institution. The business relationship is between the fintech and the financial institution. Jack Henry is not involved in that business relationship.

Please note the guidance on being careful with Jack Henry’s trademarks when it comes to issuing a press release.

Additional details

These are some additional details that you may find useful as you build your apps.

Alternatives to plugins

Plugins have a specific look-and-feel, work well for many situations, and are an excellent way to extend Banno’s user interface.

However, if you wish to extend Banno’s UI in ways which do not fit the typical pattern for a plugin, then you may want to consider creating an External application with a different Link type.

Other Link types

For more information on other Link types, see these topics on


The Banno Digital Platform™ is a multi-tenant service, which means many different financial institutions exist on the platform.

Because of this, here are a few other things to keep in mind when developing an application using the Plugin Framework:

  1. Each financial institution can enable many different external applications
  2. Each external application can have multiple Redirect URIs
  3. Each plugin is powered by at least one external application
  4. Each financial institution can enable many different plugins
