Featured APIs

Digital Identity Products

Online identity fraud continues to grow across every channel and touchpoint of the end-to-end customer engagement cycle. At Capital One, we understand that access to trusted identity information is not only critical to managing our business across the customer lifecycle – itʼs critical to digital commerce and the economy at large. That’s why weʼre excited to partner with select businesses to test a new line of Digital Identity Products that balance a simple, elegant user experience with advanced identity capabilities.

Sign Up with Capital One API

Our Sign Up with Capital One API enables end customers to start a new account or enroll in a new service with an integrated partner using their Capital One credentials. The customer provides explicit consent to pull only relevant identity data, giving integration partners an additional layer of validation in the registration and sign-up phase.

Verify with Capital One API

Our Verify with Capital One API allows end customers who use their Capital One credentials to authorize integrated partners to cross check their data by way of shared hashed identity attributes. No personal information is shared in the process, which allows partners to verify participating consumers with greater confidence and security.

Sign In with Capital One API

Our Sign In with Capital One API allows end customers to use their Capital One User ID and Password on integrated partner sites. This product includes a multi-factor authentication challenge and explicit customer consent. Leveraging Capital Oneʼs credentials also provides the benefit of strong authentication, device confidence and user verification.

Vault API

Our Vault API provides a digitally secured environment where you can deliver your customers' sensitive and critical documents (ex. utility statements, loan and legal docs). Once the customer's identity is verified by Capital One, they can easily access and manage their important documents. Whether or not they are Capital One customer, we leverage the same authentication Capital One uses to protect our customers’ financial accounts to protect your customers’ data.


We're creating rewards for finishing at the top of each API and judging category as well as recognizing overall top finishers. It's an opportunity to show what you're capable of and gain recognition for yourself and your team as fintech developers. 

Hackathon Teams

It takes all of us to build great software - developers, designers, product managers and business strategists. We all work together to deliver solutions that users love and tell all their friends about.

Hackathon teams are no different. Everybody plays an important part in the overall application – so join in the fun, even if you don’t code! If you don’t have a team, we’ll find you one where your skills are needed and you can let your freak flag fly.

Who should attend the Capital One DevExchange Hackathon? (What if I’m new to coding, a designer, etc.?)

We welcome programmers, developers, product managers, designers, and entrepreneurs of all levels at the Capital One DevExchange Hackathon. In fact, the Hackathon is a great way to expand and improve your skills. A team with varied skill sets can collaborate to generate new ideas and solve problems.

Why should I attend the Capital One DevExchange Hackathon?

First of all, it’s fun! The event brings together talented people as well as experts from Capital One DevExchange and Amazon Alexa, and it offers an opportunity to learn a ton of new and exciting skills - all in one day. Of course, there will also be lots of food, prizes and awards for the top finishers.

What should I expect at the event?

The Hackathon will task participants to work with a team of fellow developers, designers, and product managers to build new apps using the Capital One DevExchange suite of APIs. In addition to CapitalOne DevExchange APIs, the Amazon Alexa team will be on hand to help teams integrate Alexa Skills into their apps. With resources to learn how to build Alexa Skills into new applications, and awards for the best integration of Alexa UX, this offers an opportunity to work with cutting edge voice control technology as well.
