    55 Most Useful Finance APIs for Your Digital Startup

    A digital startup can bring its owner a considerable profit with the right approach to development. And the right approach implies not only the use of effective innovative technologies but also the opportunity to save in the process without losing quality. Among other things, special application programming interfaces, the so-called finance APIs, are able to help. They'll reduce your time and money costs by simplifying the creation of a website or app.

    In this article, we're going to describe 55 paid and free APIs in detail, so you'll have plenty to choose from if you decide to start your own online project.

    Why we need finance APIs

    What is meant by a digital startup? In fact, there are many worthy ideas:

    • Online stores of any format: stand-alone or complementing the real ones;

    • A virtual representation of a chain of restaurants or cafes. Such a representation (this is about sites or apps, of course) will help customers order home delivery of your meals;

    • Beauty salons. Again, we’re talking about supplementing your salon with a convenient online resource to allow users to communicate with beauty specialists remotely and without calling.

    In general, the matter concerns any project, one way or another connected with orders of goods or services and various kinds of monetary operations. A project of the sort needs reliable API based solutions to implement secure transactions, billing, and more.

    6 years after its creation, namely in 2013, Braintree was bought by PayPal: the company paid as much as $ 800 billion. Despite this, Braintree remains quite independent, and PayPal just provides it with a sort of heavy support.

    By the way, we've already talked about 11 payment APIs in one of the articles. These APIs are focused on Android developers. Follow the link to learn more.

Today, MasterCard services include the ability to perform money transactions using the web and mobile devices, through different digital channels: whichever is convenient for a particular user.

    And the next step in the MasterCard growth was the provision of new API options.

    The company hopes that such a doing (willingness to open its technology to developers) gives it a great chance to compete more effectively with market monsters such as PayPal, Square, and Visa.

    new API options

    Visa

    The Visa brand is no less famous than MasterCard. Having achieved success in processing payments, the company came to the conclusion that it was time to transform its technologies into a reliable API.

At the same time, the company uses an advanced, reliable, and well-tested TouchID or FaceID system, which makes it possible to verify the identity of the buyer as easily as possible and reduce the risk of fraud.

    • payment processing format.

    Payments API

    key API features

    Worldpay

    Worldpay is gaining more and more loyal customers and expanding its business worldwide. It has every chance of becoming a dangerous rival to PayPal.

    finance APIs

    Klarna

    The Swedish payment acceptance company Klarna has many benefits, however, the feature that made it special is the possibility of deferred payment for goods when shopping in online stores (of course, the buyer must first pass an automatic security check).

    The seller gets his payment in any case, and immediately, and the buyer can pay after 14 days. All he needs to do is to enter his e-mail and contact information, including the delivery address. Usually, the buyer parts with his money (more often in cash) at the time of receiving the parcel with his purchase.

    How does Klarna work?

    Verification is based on a special smart technology that analyzes the nature of a particular user. The calculation takes advantage of the data entered by the client, as well as the information the system gets from its internal sources. As a result, Klarna can conclude whether the potential buyer is worthy of trust.

    In addition, the company acts as an intermediary in payments, storing data about the user's bank card, thereby saving his time afterward (something like “Amazon One Click”).

    And, of course, Klarna also offers its own API, which allows developers to create their web-based payment applications.

    P.S. In Europe, the company gained popularity thanks to countries such as Germany, where people don’t trust bank cards and prefer paying in cash.

    top Finance APIs

    WePay

    WePay, a system focused primarily on online payments, was created with the expectation that the platform could successfully compete with PayPal.

    Benefits of WePay:

    • flexible API based solutions;

    list of APIs

    Banking APIs

    Banking operations are somewhat similar to payment solutions but they offer more functionality. Also, sometimes banks create their own digital systems and provide developers with these new API options to interact with their platform.

    TransferWise

    TransferWise can be attributed to the previous section, as well as to this one. Among the features of the service, there are both payment and banking solutions (see below).

    TransferWise is famous for its low-cost system of transferring money abroad - otherwise, the procedure can become rather expensive (by the way, the brand name eloquently indicates the main advantage of the platform!). TransferWise helps save up to 90% on reducing hidden bank fees: the service is so popular that Richard Branson himself invested in it.

    TransferWise is a much cheaper alternative to PayPal when it comes to international transfers. No wonder developers are increasingly resorting to using its list of APIs in order to embed a convenient and financially affordable payment system on their websites. Moreover, installation fees aren't required!

    Alas, TransferWise has one drawback: your company should be registered only in a country that supports this platform, namely:

    • EEA countries (EU, Norway, Iceland, Liechtenstein),

    • United Kingdom;

    • Guernsey; 

    • Isle of Man;

    • Switzerland;

    • Jersey;

    • the Philippines

    • Pakistan;

    • India.

    Plaid

Developers interested in creating various financial tools can, instead of contacting each bank separately, resort to Plaid. The company has already agreed with the largest and medium-sized US banks, and the developers have little to do: their task is to embed Plaid technology in the resource, and that’s all! 

    The company’s business is going well, and in early 2019, Plaid announced the purchase of its competitor, New York-based Quovo. According to CNBC, the deal amounted to $ 200 million. And now Plaid and Quvo are working on a special project - an innovative product, which makes it possible to create financial apps of any type: from lending to payment processing and asset management. These new API options are going to open great prospects for developers and fintech startups.

    Another sign of success is the expansion of the availability of Plaid: the service has recently begun to work in Europe (as stated on the main page of the site).

    So Plaid is definitely a good choice to develop finance apps and sites.

    GoCardless

    GoCardless has taken a fairly innovative approach to banking. The system offers its clients to accept payments directly from the buyer's bank account, without resorting to the help of the card system. Such a direct debit method allows saving on tax fees, which made the service very attractive in the eyes of customers who like the idea of ​​cheapening transactions as much as possible.

    At first, GoCardless was just a British startup aimed at its local market, but the company is gradually expanding its territorial reach and confidently entering markets of other countries. The next stage of growth was the development of an application programming interface - one of the new API options.

    Using these tools, developers can access the core functionality of GoCardless. In essence, the goal of the platform is to join the ranks of leaders such as Mastercard, Visa, and PayPal.

    The only fly in the GoCardless ointment is the slowness of processing bank payments. Therefore, the GoCardless system is rarely used in large online stores and other similar resources where transaction speed is a decisive factor.
