Mambu Setup
The steps on this page help you set up your Mambu environment to use the Mambu-nCino Loan connector.
Set user permissions
To configure user permissions in the Mambu UI go to the Administration tab, then Access, then open the Users section and click Actions > Edit for the user you want to edit. The Mambu user should have Mambu and API access rights.

The minimum required user permissions to use the connector are:
Entity | Permissions |
---|---|
Clients | - View Client Details - Create Clients - Edit Clients - Approve Clients - Manage Client Association |
Groups | - View Group Details - Create Groups - Edit Groups - Approve Group - Manage Group Association |
Products | View Loan Product Details |
Loan Accounts | - View Loan Account Details - Create Loan Accounts - Edit Loan Accounts - Delete Loan Accounts - Approve Account - Request Loan Approval - Disburse Loans - Edit Loan Tranches - Set Disbursement Conditions - Manage Loan Association |
Products and fees configuration
- Open your Mambu tenant and start creating the loan products with your desired settings and fees. Keep in mind that the same fees need to be configured in nCino as well. The fees must be set as optional in Mambu. This means that the fee is applied on the loan account only if provided by nCino. Supported settings for loan products can be found in the table below.
Product setting | Value |
---|---|
Product type | - Fixed Loan - Dynamic Loan - Revolving Credit - Tranched Loan |
Interest Calculation Method | - Flat - Declining Balance Equal Installments - Declining Balance |
Interest Rate Source | -Fixed Interest Rate - Index Interest Rate |
Payments Method | - Standard Payments - Optimized Payments - Balloon Payments |
Grace Period | - Principal Grace Period - enabled by default for all the products except for the Balloon Payments |
Repayment Amount - Principal Payment | - Flat Amount - % of Outstanding Principal (only for Revolving Credit) |
Repayment Amount - Total Due Payment | % of Total Balance (only for Revolving Credit) |
Product Fees | For Fixed and Dynamic term loans: Disbursement fees (deducted, capitalized, upfront) |
Start creating the fees taking into consideration the
Fee Name
in Mambu must contain thefee id
from nCino in the format{nCino Fee Id} {Mambu Fee name}
, for example020 Loan Origination
or013 Upfront Disbursement
. This step can be done in parallel with the configuration of fees in nCino or you can come back to it later to update the fee name with the ID generated in nCino. The feetypes
supported by this integration are:- Upfront disbursement
- Capitalized disbursement
- Deducted disbursement
Please Note
Percentage amount fees are always configured in Mambu with a default amount. Flat fees are always configured in Mambu without a default amount. These are the default settings in Mambu.
- Take note of the Mambu product’s
encodedKeys
as they are used in both Mambu Process Orchestrator (MPO) and nCino products configuration. You can take theencodedKey
from either the browser address bar if using the UI, or by using the get loan products API endpoint once you have created your products.
Please Note
Fees are not supported for revolving credit and tranched loans. These loan types only allow First Repayment Date
as part of the Disbursement Details
wrapper. Disbursement fees can only be added to these loan types when disbursing them.
Branches configuration
Branches are configured manually both in nCino and Mambu. They are linked through the lookupkey
which takes the value of the branch encodedKey
from Mambu. This is the only field used in the MPO logic, so the other fields can be configured as you desire. Other branch details such as state, city, address, etc, are not used in the MPO logic, but should be the same across platforms for consistency.
To do the mapping for branches, create the branch in Mambu and take note of its encodedKey
either by taking this from the browser address bar if using the UI or by using the get branches API endpoint.
Follow the steps for configuring branches in nCino in the next page.
