Navigating the World of Online Payment APIs
September 15, 2023
Application programming interfaces for payments are a great digital tool used by modern companies. As e-commerce has evolved, this kind of software has become a necessity as it helps businesses sell goods to their customers quickly and easily.
APIs link the website of a company to the payment processing network. To be more precise, payment APIs serve as a bridge between a business and a card network like Visa, allowing a company to accept online payments from its clients.
In this article, we’ll talk about the features and principles of payment APIs and explain how companies can use them to improve their business processes.
What Is a Payment API?
An application programming interface is software that connects different systems, allowing them to exchange data. APIs allow applications to both send and receive payments. These APIs are used to ensure a convenient checkout experience for both merchants and their customers. They transmit data securely so that transactions are processed quickly and accurately.
APIs enable businesses to receive funds via credit cards, bank accounts, and debit cards, giving their customers more options. Additionally, they may provide a variety of other payment methods, like PayPal and e-wallets, which enhance customer convenience.
A payout API enables companies to send payments to their contractors, vendors, and partners automatically. They help distribute mass payments to multiple recipients simultaneously, for example, to send salaries to employees, freelancers, and content creators or pay for goods and services. Payout APIs are often integrated with different payment methods, such as bank transfers, PayPal, or prepaid cards. The main benefit is that there is no manual data entry if the payments are fixed and scheduled.
Payment Gateway APIs
Another type of payment APIs is a payment gateway. These offer a secure and easy-to-use payment solution for companies in the e-commerce sector, allowing them to receive funds for goods they sell. Customers pay the amount owed to the business via any convenient payment option available, including bank transfer, debit cards, credit cards, Apple Pay, or PayPal. Payment gateway APIs provide a smooth checkout experience for customers.
How a Payment API Works
Let’s imagine you are shopping at an online marketplace, and you want to purchase a couple of items with your credit card. To do this, you fill in your card number and press “buy”. An API gathers your data and sends it further to the acquirer. Importantly, all data provided when placing an order is encrypted.
Communication with the acquirer takes place immediately. The acquirer then contacts your bank and returns the result analysed by the bank to the API. Without human intervention, your credit card information is verified, and if there’s enough money there, it goes to pay for the purchase.
So, with the payment API, transactions are analysed and approved automatically, in real-time, in just a few seconds. You won’t have to leave the e-commerce platform, enter data on a third-party site, or take additional steps. You will receive a purchase status message on the same screen where you entered your data.
The Main Features of Payment APIs
Payment APIs offer multiple advantages for both businesses and consumers, and these aren’t only connected with sending and receiving online payments. Let’s consider three main features of a payment API.
Fast and Transparent Payments
From a customer’s perspective, there’s no need to switch pages, fill in card information multiple times, or pay fees to third-party services. Moreover, APIs can avoid duplicate payments, so customers don’t need to think about this. Some APIs also inform business owners and customers about changes in the payment process so they can always stay alert.
From a business perspective, APIs bring peace of mind and organisation. The customer can pay for the goods easily, which means their satisfaction will increase. The business, in turn, will be sure that the customer’s cards are verified and that it will receive payment for its goods and services. A payment API can be used to make both recurring and one-time payments, which makes them a valuable tool for subscription businesses.
Security is crucial for both companies and customers. The Payment Card Industry Data Security Standard (PCI DSS) is a set of protocols and security measures designed to protect sensitive customer information transmitted to an online e-commerce platform at the checkout stage. A PCI-compliant payment API provides increased protection against threats such as data breaches, fraudulent activity, and other forms of cybercrime. In addition, some payment APIs help businesses comply with regulatory requirements such as Know-Your-Customer (KYC) authentication and Anti-Money Laundering (AML) policies.
An important aspect for marketplace owners is to ensure that the correct shopkeeper receives payment for the purchase. In cases where a shopping cart contains items from different merchants, using the split payment feature allows businesses to automatically split and transfer the amounts accordingly. This feature doesn’t affect the client in any way, but it makes a huge difference for businesses like eBay and Amazon.
How to Use Payment APIs to Bring Innovation to Businesses
Payment APIs help to boost customer satisfaction, deliver high-security services, and protect data. If you want to make financial transactions without building your own infrastructure from scratch, consider using a ready-made payment API to save your time and resources.
So, what can companies do with a payment API? Let’s sum it up:
- Accept credit and debit card payments
- Accept payments via PayPal, Google Pay, and other wallets (even crypto, if you want)
- Automatically verify cards and validate transactions
- Offer direct payments to various accounts based on specified criteria
- Make scheduled transactions with your suppliers
- Comply with industry regulations
What’s more, payment APIs can also integrate new products and services with existing systems, making this process much quicker and easier.
What an Ideal Payment API Looks Like
There are different types of APIs, including bank APIs, wallet APIs, payout and payment gateway APIs we discussed above and more. However, the best options have similar features and offer similar benefits. Here are the main features to look out for.
- A simple and easy-to-use API. The less complicated the integration process, the better. An intuitive API structure helps to avoid errors and reduces the time you need to integrate it.
- An API has robust security protocols. As the number of cybercrime cases increases, security features like encryption, tokenisation, and strict compliance measures become imperative.
- There are multiple transaction options, so a business and its customers can choose the most suitable one. Catering to diverse user preferences, from bank transfers to mobile transactions via PayPal, enhances customer satisfaction.
- There is clear and detailed documentation. This is an important criterion for business because ultimate guides, sample codes, and troubleshooting tips significantly smoothen the integration process.
Payment APIs ensure that financial operations are swift and secure. When combined with a user-friendly interface and simple integration process, an API becomes the best tool to use. Overall, as a business, you should be looking for a functional, reliable, and easy-to-use API.
