Early Access Feature
The following feature may incur additional costs. If you would like to request early access to this feature, please get in touch with your Mambu Customer Success Manager or contact us through Mambu Support to discuss your requirements.  For more information, see Mambu Release Cycle - Feature Release Status.

Mambu Functions help you enhance your financial products by extending the functionality of the Mambu composable banking platform. Using Functions reduces the time it takes to create custom financial products and gives you the power to customize for your unique requirements by injecting your own code into existing business processes.

You can write custom functions in TypeScript or JavaScript that draw on Mambu data. For example, you may use Functions to create the following common custom processes:

  • Create custom deposit fees for clients.
  • Create custom monthly deposit fees.

The Mambu Functions Management APIs allow you to deploy your custom code, and see a list of your deployed Functions.

Please note

Early versions of this feature are limited to the calculation of fees in Deposit products, either manually or monthly.

How Functions work

Mambu Functions apply your custom logic when a process attached to a product is invoked. For example, you may want to apply a special fee class every time a deposit is made by clients with over EUR1000 in their account. Instead of being limited to the options in Mambu, you can code your own logic using data from the banking platform.

Once the Function has been deployed, it can be bound to a product using the Mambu UI - when choosing product configuration features such as deposit fee - and it will be invoked when the relevant API is called.

You can create Mambu Functions for the extension points listed in the Core Extensions page. Each extension point has ready-to-use templates that you can use to start your development.

Restrictions and security

Mambu Functions are run in an isolated environment for security purposes. Functions may only access and use data supplied by the Mambu cloud banking platform. To ensure that Mambu Functions do not affect the functioning of the cloud banking platform, check the individual pages under Core Extensions and Event Driven Functions for the current restrictions imposed.

You are responsible for running thorough functional tests of your Functions before deploying them to your production environment.

Please note

API keys used by the Mambu CLI are not encrypted at rest in the credentials file. Please ensure that your local disk is encrypted and that your workspace is secure.

Getting help
