Introduction At Cross River, we are focused on making financial technology more efficient for our partners. We understand that B2B data exchange can be complicated, especially in regulated industries like lending and payments. That’s why we are working on a new approach to partner integration—one that improves data validation, schema flexibility, and user experience to make collaboration smoother.

Most API integrations rely on fixed JSON schemas, forcing partners to adapt to rigid data structures. This can lead to inefficiencies, requiring partners to send redundant data, deal with validation errors, or go through multiple iterations before getting the integration right. Regulatory changes like 1071 compliance add even more complexity, making flexibility important.

To address these challenges, we are developing a new B2B integration platform that allows partners to define, customize, and validate JSON schemas more dynamically. We are starting with our Lending and Credit Card partners, who face the greatest challenges in adapting to evolving data and compliance requirements. The key improvements include:

We want to build this with input from our partners. As we refine our integration platform, we are inviting fintech companies and marketplace lenders to help shape the design. By participating, partners will gain:

We aim to improve how financial data is exchanged between businesses. With scalable and adaptable integration tools, we are making it easier for partners to work with us.

If you’re a Lending or Credit Card partner interested in collaborating, we’d love to hear from you. Reach out to our team and be part of the next phase of B2B integrations.

Cross River Bank is excited to announce an enhancement to our Lending process, designed specifically for our valued Marketplace Lending (MPL) partners. The new solution streamlines the process of purchasing loans, delivering efficiency, transparency, and control. After the designated seasoning period, MPLs repurchase originated loans from issuing banks. With our enhanced Lending Selling solution, MPLs can access a user-friendly interface or integrate with our Lending Selling API . Log on in the morning and see loans scheduled to be purchase that day.

We’re proud to announce that the enhanced Lending Selling solution is now live for Held for Sale (HFS) loans, enabling MPLs to immediately benefit from this streamlined process.

Looking ahead, we will be expanding the platform to enable management of loans in a warehousing facility , ensuring full coverage to meet your needs.

We’re committed to empowering our MPL partners with tools that make loan buyback processes faster, smarter, and easier. Whether you prefer the hands-on control of our UI or the automation of our API combined with the proactive capabilities of webhooks, Cross River Bank is here to support your success.

For access requests, inquiries, or feedback, please don't hesitate to contact our dedicated support team at [email protected]. To access the UI, your user will need COS Lending Selling permissions from an allow-listed static IP address.

We're thrilled to announce a significant milestone for Arix, CRB's loan validation and funding system. For the past five years, Arix has empowered Marketplace Lending (MPL) partners with an API-only integration. Today, we're excited to unveil a complementary addition: Manual Review, a UI designed to enhance the loan review experience and speed up onboarding.

In response to your feedback, we've developed Manual Review, a UI that integrates with our API-driven system. Now, you have the flexibility to choose between API calls or intuitive UI interactions for loan management tasks. The system currently shows all the loans that have not automatically proceeded to funding.

As we celebrate this milestone, we're committed to further enhancing the Arix experience. In future releases, expect even more features and refinements aimed at optimizing loan processing efficiency and compliance management.

For access requests, inquiries, or feedback, please don't hesitate to contact our dedicated support team at [email protected]. To access the UI, your user will need Oversight and Loan Edit permissions from an allow-listed static IP address.

Here's to a future of seamless lending with Arix!

Building and optimizing a lending platform takes time—and testing should be frictionless. At Cross River, we’re making it easier for our partners to validate loan funding and loan purchasing flows without triggering full compliance checks in the sandbox environment.

Now, by adding the "BypassRuleChecking" key in the Field5 JSON, you can bypass compliance rule checks during sandbox testing. This lets you focus on funding mechanics and iterate faster, without waiting on full verification cycles.

As always, we’re here to help. Reach out with any questions.

We’re excited to announce the launch of our new web-based app for viewing loan application data that’s sent using our Fair Lending API set. This new user interface (UI) lets you view, sort, and filter loan application data, making it more efficient to access the information you need for successful implementation of our APIs.

One of the major benefits the UI gives is the ability to view a large amount of data without the need to pull it via API. You can access the information you need without having to deal with any technical details or coding. The app is ideal for anyone who needs to review loan application data on a regular basis. It also makes onboarding to our systems easier.

Here’s a view of a denied application, including the reasons the loan application was denied.



Another benefit the new app gives is the ability to navigate through information, without being overwhelmed by the amount of data needing to be collected. This is sometimes hard to do in a single large JSON object.

This image shows a drill down into an approved application that’s been accepted by the customer.



Overall, our new UI for viewing loan application data is a valuable tool for anyone who needs to access this information. Whether you're a loan officer, Fair Lending specialist, or just someone who needs to view data as part of your job, this new web-based app makes it easy to get the information you need quickly and efficiently.

Arix is thrilled to introduce two new rails to our collection, bringing our total to eight!

These rails can be utilized through the Arix APIs, just like one would call the other payment rails.

The wide range of payment rails wasn’t always available directly in Arix. Workaround solutions were found by using the XPay rail for internal transfers and then sending funds from your account using another payment method.

It's time to ditch the two-step solution.

Here's why:

Upgrade your loan processing experience with ArixWires and Card Payment Rails. Explore the possibilities of these new additions, now totaling eight rails in our comprehensive system.

Curious about how to sign up or want to explore these new features further? Reach out to your dedicated relationship manager today. They're here to guide you through the seamless integration of these rails into your loan operations.

My name is Ari Pollack and I’m a Product Manager on the lending team. I’m excited to announce the release of our newest set of APIs, Cos.Lending PreApproval. At this first stage, you can send application data to Cross River for all applications (originated, approved-not-accepted, denied, withdrawn, rejected, incomplete, and if applicable, in progress).

Regulatory agencies across the industry recognize how unique our business model is, and have been scrutinizing FinTech lending activities as it relates to Fair Lending. As a partner, expect an annual examination as regards fair lending, in addition to regular examinations. The bank’s prudential regulator, the FDIC, expects us to evidence collaborative data management practices between Cross River and its partners.

Until recently, only approved and ready to fund loans were sent via API to the system. All other application information was sent daily, as files via sftp. Partners often received feedback from regulators, months and even years after the data was sent in which led to burdensome research to fix old data. With the new Application API, we validate each field on submission, and return instant feedback in the response of the API call. Required fields are enforced so that an application can be recorded. For example, the Approve API in the image below where an application is being sent in and marked as Approved.

In the API response you can see immediate feedback. The borrower had an illegal email address and the postal code was also not valid. Now, the submitter will know what needs to be fixed much earlier on in the process.

For Fair Lending purposes, we are not only required to collect information about approved loans, but also for denied, rejected, or undecided applications. Below is an example of an application submission to the API with a decision of Denied. As you can see in the image, there is a list of denial reasons in the body of the API call along with the application itself.

Ultimately, this API strengthens data governance and regulatory exam management processes.

While it will take some level of effort to integrate, the benefits of the API process include:

The FDIC expects to receive complete and accurate data in a timely manner during the regulatory examination process. The API process will go a long way in meeting those expectations and minimizing potential scrutiny by the examiners, which helps everyone involved.

Don’t start eulogizing the paper check just yet. Our “Check in the Mail” keeps gaining popularity. This release allows for scalability, security, and a better user experience for our partners.

At the end of 2020 we launched our Check in the mail rail. MPLs use checks to give their customers the option of receiving funds or paying off their existing loans via a paper check. Very old school, yes, but our MPL customers jumped at the option.

Our vendor, Checkbook, did a great job of printing and sending out the checks. Because of our architecture, they also managed the check clearing. As the volume increased though, relaying details of cashing, revoking, and expiring checks became a non-scalable procedure.

To address that issue, we needed to automate the clearing of the checks in-house. COS, our banking core, added a Positive Pay feature, and once the system integrated that feature, check events could be automatically handled.

When a check is created, the system adds it to Positive Pay in COS and it has an expiration date. The check is then printed and mailed out by Checkbook. When a customer tries to cash the check, the fed notifies CR, and COS reviews the check. The check only gets cashed if all 3 conditions are met:

The system can revoke a check if MPL Operations or the MPL wants to stop a check from being cashed. And, if any of the 3 conditions are not met, COS will bounce the check when someone tries to cash it.

Any event that stops a check from being able to be cashed, such as an expired event or a revoke, will create a return event for that check. After a return, you'll be able to request the funds again by check, or by another payment method.

Should I state the obvious? OK, I will.

Since the fed will now send the cash request to CR, cashed events will now be in real time. No tech changes required by our MPL customers. Relax and enjoy the improved experience.

You may notice these features that we added:

Any failure to create a check will result in a return. This will allow the rest of the loan amount to be disbursed using a different rail.

We are working with Checkbook on other possible mailing options (at present, only USPS).

If you are an MPL that’s keen on disbursing via digital rails, of course we support those as well as payment rails. If a business opportunity arises that requires more traditional payment methods, we’ve got you covered. We’re not burying the paper check just yet.
