Early Access Feature

If you would like to request early access to this feature, please get in touch with your Mambu Customer Success Manager to discuss your requirements. For more information, see Mambu Release Cycle - Feature Release Status.

A loan product allows you to set up, in advance, the parameters for a type of loan that you wish to offer. Loan products are flexible and highly customizable templates for creating individual loans. For more information, see Setting Up New Loan Products.

With Configuration as Code (CasC), you may batch configure your loan products configuration via Mambu API v2 using YAML. For general information on CasC, see Configuration as Code Overview.

API operations

CasC for loan products supports two operations.

Action	Endpoint	Description
`GET`	`/configuration/loanproducts.yaml`	Get current loan products configuration.
`PUT`	`/configuration/loanproducts.yaml`	Write a new loan products configuration to Mambu.

Please Note

If you write a PUT configuration to Mambu, any loan products not included in the new YAML configuration will be deleted - if possible.

If the loan products cannot be deleted, you will receive warnings.

Requests

For general information on CasC requests such as authentication and required headers, see Configuration as Code Overview.

The following section shows sample requests using curl and basic authentication. For all examples, replace TENANT_NAME with your actual tenant name. {auth} is the base64 encoded value of username:password. For more information, see Authentication in our API reference.

Additional headers

You may send synchronous or asynchronous PUT requests.

Please be Aware

If you have more than 60 loan products, we recommend you make your request asynchronous.

To use the endpoint asynchronously, you must provide two additional headers:

X-Mambu-Async with a value of true.
X-Mambu-Callback with the callback URL.

The expected status code in case of a successful asynchronous request is 202 Accepted. When the update configuration operation is completed, a message will be posted to the provided URL with information about whether the updated request completed successfully or not.

GET configuration

Get loan products for all product types

curl -X GET 'https://TENANT_NAME.mambu.com/api/configuration/loanproducts.yaml' \
-H 'Accept: application/vnd.mambu.v2+yaml' \
-H 'Authorization: Basic {auth}'

Get loan products for specific product types

To retrieve loan products for specific product types, you may use the type query parameter. You may specify more than one product type.

The following example returns all loan products for the revolving credit and dynamic term loan product types.

curl -X GET 'https://TENANT_NAME.mambu.com/api/configuration/loanproducts.yaml?type=REVOLVING_CREDIT&type=DYNAMIC_TERM_LOAN' \
-H 'Accept: application/vnd.mambu.v2+yaml' \
-H 'Authorization: Basic {auth}'

PUT configuration

curl -X PUT 'https://TENANT_NAME.mambu.com/api/configuration/loanproducts.yaml' \
-H 'Accept: application/vnd.mambu.v2+yaml' \
-H 'Content-Type: application/yaml' \
-H 'Authorization: Basic {auth}'  \
--data-binary @loanproducts.yaml

@loanproducts.yaml represents the absolute path of the file on your device. Use the --data-raw flag if you want to specify the YAML body inline.

Replies

If you do not receive a 200 OK response then fix any validation errors and make another PUT request until you receive a 200 OK response.

Please Note

If you PUT a valid YAML configuration to the API and you do not receive a 200 OK status code within 60 seconds, you may receive a 504 Gateway Timeout status code. We expect all responses to be below 60 seconds.

If you encounter this issue, please contact us through Mambu Support so we can investigate it.
