Lumin Digital launches open banking integration with MX

Lumin Digital has launched an open banking integration with MX, giving financial institutions on its platform a way to connect users with third-party financial applications.

The integration lets retail and business users connect bank accounts to supported external financial apps without sharing usernames and passwords. It uses application programming interfaces and OAuth 2.0 authentication to give users more visibility into how their financial information is accessed and shared.

The move reflects a broader shift in financial data sharing away from screen scraping, in which customers hand over login credentials to outside services so account information can be collected. Instead, banks, credit unions and financial technology providers have increasingly backed application-based connections that let customers grant and withdraw permission directly.

The MX connection is being offered through Lumin FDX, Lumin's framework for standards-based financial data sharing. Built on specifications established by Financial Data Exchange, the framework is designed to support multiple aggregation providers through a common approach.

That structure is intended to help financial institutions connect consumers and businesses to a wider range of financial applications while giving users a clearer view of which services can access their information. Users can also revoke access for individual third-party apps.

How it works

The direct API connections are designed to improve reliability and support near real-time access to connected financial services. The arrangement also aims to reduce repeated reauthentication by maintaining supported persistent connections between institutions and approved third-party apps.

For banks and credit unions using Lumin's digital banking platform, the integration adds another way to offer account connectivity to customers who want to use budgeting tools, payment services and other financial applications. The MX integration is now being rolled out across Lumin's client base.

Lumin also plans more aggregator integrations for the same framework, signalling an effort to support a broader set of data-sharing connections rather than relying on a single provider. That could help its banking and credit union customers meet demand from users who expect access to a range of external financial tools within secure permissioning systems.

Sean Weadock, Chief Product and Technology Officer at Lumin Digital, said the move reflects changing market standards.

"The future of financial data sharing will be defined by secure APIs, consumer control, and greater interoperability," said Sean Weadock, Chief Product and Technology Officer, Lumin Digital. "Our integration with MX strengthens Lumin's ability to help financial institutions navigate that shift with an architecture designed to evolve alongside industry standards and regulatory expectations."

MX framed the integration around user choice and oversight of personal financial information. The company works with financial institutions and financial technology groups on data connectivity and data use.

"Open banking succeeds when people are in control of their financial data," said Jane Barratt, Chief Advocacy Officer and Head of Global Public Policy, MX. "By working with Lumin, we're making it easier for financial institutions to deliver secure, consumer-permissioned connectivity that gives people greater transparency into how their data is shared and the confidence to connect with the financial tools they choose."

The arrangement highlights how digital banking providers are building open banking features directly into their platforms as financial institutions face rising expectations around permissioned data sharing, transparency and user control.

By tying the MX integration to Financial Data Exchange specifications, Lumin is positioning the service around a common industry framework rather than proprietary account-linking methods. Using a shared standard may also make it easier for institutions to add more data connections over time while keeping the same basic controls for consent and access management.

The integration is rolling out to financial institutions on the Lumin platform.
