Top Financial Data APIs - United States

Financial data APIs (Application Programming Interfaces) are software components that enable seamless interaction between financial applications, allowing for easy access to information, transactions, and payments. Financial institutions use these APIs to simplify integration, enhance collaboration with financial partners, and improve the overall customer experience. The primary function of a financial data API is to provide users with access to financial information exactly when they need it. These APIs connect disparate applications, enabling smooth data sharing between them, whether for consumers, third-party vendors, business partners, or company employees. Businesses also utilize these APIs to synchronize data across multiple platforms. These APIs work by connecting to legacy financial systems, processing incoming requests, retrieving the relevant data, and sending it back as a response. Users rely on financial data APIs to link and access information stored within larger financial applications and databases.

Essentially, it serves as the link between banks and financial technologies. Several noted brands like Gusto, Venmo, TransferWise, Charity Water, Robinhood, and Level Money currently use Plaid’s products and solutions. In the case of popular integrated online HR service Gusto, it uses Plaid’s automated clearing house (ACH) functionality to power its payroll direct deposit service. Other fintechs such as budgeting app Level Money utilize the platform to consolidate and clean data from user’s various bank accounts to help them manage and budget their money. In a broad sense, Plaid spans critical segments of financial services including setting up payments and validating financial data. It can help you arrange and execute ACH payments, collect transaction data, validate user’s identity, examine employment and income data, assess the riskiness of users, and embed bank integrations directly inside borrower flows. Developing your own application has never been made easier – with just a few lines of code, you can fit Plaid into whatever you’re building. Overview of the Plaid benefits: Better ACH authentication Authenticating accounts for bank-to-bank payments is made simpler, faster, and more user-friendly. You’ll be able to instantly authenticate transfers without waiting for micro-deposits as well as reduce failed transactions by authenticating and steering users toward ACH. This results in a seamless user experience since you can set up users based on information they already know, effectively eliminating checkbook hunting. It likewise boosts conversions by letting you deploy a mobile-optimized flow that converts much better. Check balances in real-time Working with financial data is simplified with Plaid. In just a few steps you can pull historical data and real-time balance, and get current and available balance info and details about account status and type. You can check in an instant your users’ balances whenever you need to make a transfer. It helps prevent overdrafts and enables pre-funding of transactions with insight into balances. Furthermore, by gaining visibility into available funds before you transfer, you prevent non-sufficient fund (NSF) fees, thereby, reducing if not outright eliminating fraud cost. Curtail bank fraud Plaid enables you to use bank data to verify identities and reduce bank fraud. You can substantiate user identities such as name, phone number, address, and email, and check the information against what’s on file at the bank. You’ll be able to know your users through simple identity check which is further facilitated by auto-fill forms based on account holder info on file with the bank. Clean & categorized transactions Money management is streamlined when you get clean, categorized transaction data that goes back as far as 24 months. You’ll have better details about transactions when placed in context with geolocation, merchant, and category information. With reliable, real-time data that stretches as far back as possible, you gain valuable insights to serve your customers better and reduce cost with low-latency connections that don’t require additional technical resources. Verify borrower assets straight from the source Borrowers can link their bank accounts in seconds to maximize conversions. You get fast processing speeds with a integrated technology that seamlessly connects Plaid into your own experience to reduce friction for borrower. Also expediting connections is the commitment to security such as the use of enterprise-grade 256-bit AES encryption that comes with regular network penetration tests and security reviews.
