Description

https://developer.xero.com/documentation/api/finance/overview

Release Notes

The Finance API is a collection of endpoints which customers can use in the course of a loan application, which may assist lenders to gain the confidence they need to provide capital.

The Finance API is a closed API that is only available to those that have an established (usually, but not limited to, financial services) partnership with Xero.

If you're an existing partner that wants access, contact your local Partner Manager.

If you're a financial institution or other partner who wants to leverage the Finance API for your business customers, contact us to become a financial services partner.
