Developers are one of the cornerstones in the age of omnichannel customer service. You can’t build a successful business without proper processing of all the data, especially when it comes to payment information. To ensure a seamless experience for all parties involved, providers enable developers to use APIs, greatly simplifying the company’s interaction with the customer and vice versa. This is especially true for acquiring banks, payment service providers, as well as merchants, for which convenience and speed of interaction are always the top priority. In fact, API is a key value provided by an acquirer or PSP for medium and large merchants who want to embed payment instruments directly into their backend and business ecosystem. So, let’s have a look at what is a payment gateway API and what features should be considered by developers when choosing one.

What is a payment API?

So what is an API for payment gateway? Basically, it is the software needed to integrate the payment solution with another, existing application. To put it simply, a payment gateway API is a “layer” between two different systems. With the help of this intermediate layer, systems exchange data and perform various functions. An excellent example of payment API implementation in payment acquiring network is the connection of the checkout function to the payment system.

API for payment gateway is extremely convenient because it does not require the customer to visit another site as well as allows merchants to use all the functionality of the back office at the level of their custom business ecosystem. Thus it increases the probability that clients finish the transaction and buy everything they planned and the merchant will not have to work with several different products, combining their business processes in a single interface.

What can your merchants do with API integration for payment gateway?

Payment APIs allow merchants to avoid building a payment processing infrastructure from scratch, which saves time and gives more control over the customer experience. Here are a few examples of what merchants can do with a payment API:

  • Accept payments by credit and debit cards
  • Accept extra types of payments (e.g. ACH or foreign payment methods)
  • Set up recurring payments/periodic billing
  • Customize fields in the checkout
  • Perform bank transfers
  • Accept cryptocurrency as payment
  • Route payments to various accounts according to set criteria
  • Configure security features
  • Submit invoices

4 Benefits of a payment gateway API

In addition to the basic functionality of being able to accept payments, payment gateway API integration has a number of other advantages.

Interact with customers in more than one place

Merchants can greatly expand the geographic reach of customer interactions. Having reliable APIs for developers allow for the integration of mobile and contextual payments into the payment infrastructure. Thus, the number of places of interaction with the customer increases significantly.

Smarter marketing decisions

With the payment gateway APIs you can collect purchase data in real time. So a well-designed API can be a powerful tool for understanding customer behavior and building business strategies.

Wide variety of payment options

Good API for payment gateway allows users to accept all payment options i.e. all types of credit cards, alternative payment methods (like PayPal or Visa Checkout), and international currencies. This flexibility can make it much easier to do business in different regions.

Customer data remains safe and secure

The use of APIs ensures that there are no security risks because the responsibility for customer data is on the software provider, as well as the concern for confidentiality of payment card fields. Merchants no longer need to store data on their own websites as a modern API is equipped with multiple layers of security in compliance with all regulations.
