So, What is a Payment API?

At its core, a Payment API (Application Programming Interface) is a set of protocols, tools, and definitions that enable software applications to communicate and interact with payment processing systems. They act as bridges that facilitate the exchange of payment-related data between different entities involved in a transaction including merchants, customers, payment gateways, and banks.

When you think about your business’ e-commerce website, your customers can easily browse through your product list, add items to their carts, and complete their payments with just a few clicks. Have you ever wondered how your customer payments reach your company’s bank account? This is where payment APIs come into play.
The payment API is generally used to secure the information and transaction exchange between your business and clients. Instead of having your accountants manually verify and record each transaction, the API acts as your channel to process outgoing or incoming payments.

How Payment APIs Work

Understanding the flow of information within a payment API can be quite confusing. So, here’s a breakdown of what payment APIs can do to give you a clearer picture of its functionality:

1. 1

   Checkout Initiation

   This is when your customer reaches the checkout page of your website and enters their payment information (credit card details, e-wallet login, etc.).

2. 2

   Secure Transmission

   As your customers input their information, your website does not store their data. Instead, the information is communicated to the payment API using encryptions. This encryption scrambles your customer’s information, making it unreadable to anyone who might try to intercept it.

3. 3

   Bridging the Parties Involved

   The payment API acts as a secure bridge between your website and the chosen payment processor (Visa, Mastercard, PayPal). It sends your client’s encrypted payment information to the processor for verification.

4. 4

   Verifying Payments

   Once the processor receives the payment information, it verifies customer data like card details or checks for sufficient funds in the customer’s account. This ensures the legitimacy of the transaction and can involve communication with the customer’s bank for authorization.

5. 5

   Confirmation

   After verifying the data, the payment API relays the approval (or decline) message back to your website to let it know whether your customer’s payment was successful or not

6. 6

   Order Fulfillment

   If the payment is approved, your website can finalize your customer’s order and let them know that their order has been placed––initiating the order fulfillment process (product preparation, shipping, tracking, and after-sales servicing).

To further simplify this process, imagine that this is a restaurant. The customer is your website, the order is your client’s information, the waiter is the payment API, and the kitchen is the payment processor. The customer places their order with your waiter. The waiter then securely relays the information to the kitchen to process the order. Once the order is confirmed, the waiter returns to the customer to confirm their order. This is generally how payment APIs work.

Benefits of Using Payment API

Integrating payment APIs into your e-commerce business platform offers numerous benefits if you plan on accepting payments online or through mobile applications. Some of the key advantages include:

Enhanced Security

Payment APIs act as a secure intermediary, minimizing the risk of data breaches on your website. By handling sensitive payment information through encryption, they safeguard both your business and your customer’s financial data.

Streamlined Integration

Integrating various payment methods like credit cards, debit cards, and e-wallets into your website or mobile app becomes significantly easier if you use payment APIs. They provide readily available tools and functionalities, eliminating the need for complex coding to build your payment infrastructure from scratch. 

For instance, using Brankas Direct can securely connect your website directly with banks and other financial institutions through its built API system. Adapting this product to your business removes the need for internal payment stream creation.

Convenience for Customers

Payment APIs contribute to a smoother and more familiar checkout experience for your customers. By supporting a wide range of popular payment methods, the system offers flexibility and caters to your customers’ diverse payment preferences. This can lead to increased conversion rates and reduced cart abandonment during checkout.

As an example, using Brankas’ Merchant Link lets your website accept payments with any available method on the internet. Whether it’s through Visa, Mastercard, or other private financial institutions, you can easily integrate the Merchant Link into your system and customize it based on your business needs.

Scalability and Growth

Payment APIs are designed to handle large volumes of transactions efficiently. As your business grows and your customer base expands, this payment processing infrastructure can scale to accommodate your increased demand. 

A product reflective of this feature is Brankas’ Disburse. With this payment API, you can automate sending funds from your corporate bank account to your vendors, customers, employees, or anyone who needs to receive money from your organization. You can even schedule your payments ahead of time. 

Systems like Brankas Disburse can ensure smooth operations and avoid bottlenecks during peak transaction periods.

Customization Options

Many payment APIs offer customization features that allow your business to tailor the checkout process to your brand and customer needs. You can integrate the API with your existing website design, creating a cohesive user experience.

Ultimately Payment APIs can offer your business a more convenient way of performing online payment transactions. They can enhance data security, streamline your payments, and provide convenience for all your users. Utilizing payment APIs can create an efficient financial processing system that supports your business goals while fostering a positive customer experience.
