One Mortgage System (OMS) has expanded the functionality of its full application programming interface (API) link with Nationwide Building Society.

Brokers using OMS can now submit decisions in principle (DIPs) for all Nationwide’s mortgage applicants, including self-employed, contractors, foreign nationals and those looking for interest-only.

The integration supports key product options, such as Helping Hand and Extra Help.

In addition, product reservations can now be undertaken within the OMS platform.

Fact find information from OMS is passed directly to Nationwide without the need to rekey data into Nationwide for Intermediaries online.

Once submitted, Nationwide’s decision is returned directly into the OMS platform, allowing brokers to review, amend and resubmit if necessary. Brokers will also receive a DIP certificate within OMS if required.

When they proceed to full application, all personal information and lending requirements are transferred automatically to NFI Online and any supporting documents can be requested from the client using the integrated checklist step.

One Mortgage System managing director Neal Jannels says: “We’re always listening to what our lending partners and our users need and this speedy upgrade to the initial Nationwide integration reflects that.”

“The result is a more complete, end-to-end journey for a wider variety of cases. It streamlines submissions and removes duplication, helping brokers and clients reach the right outcome more quickly and accurately.”

Nationwide head of intermediary digital Andy Tilsley adds: “We continue to support the intermediary market by making it easier and quicker for brokers to do business with us. We’ve worked closely with OMS to enhance the digital journey to improve the quality of submission and save broker’s time.”

In March, OMS connected with Nationwide’s API provide quicker decisions for brokers.
