Nationwide’s mortgage API

Here at Nationwide, we’re always looking for ways to help brokers submit business easier and more efficiently.

So with this in mind, we’ve developed a mortgage API (Application Programming Interface) which will allow Remortgage and Purchase DIPs to be created in third party platforms.

Once an API DIP is completed, the case can progress to a full mortgage application in NFI Online.

Who have Nationwide integrated with so far?

  • Twenty7Tec

We are working to integrate with other third parties and this page will be updated with further details.

What can be done through our API?

We’re still developing our API, so the application types that can be submitted through these Third-Party Platforms are restricted. You can review the below information to check whether your application can be submitted through the API. Any applications that cannot be submitted through the API, can continue to be keyed via NFI Online.
