What is a payment gateway API?

Thanks to encryption, the gateways make the transfer of sensitive confidential information easier, such as credit card numbers, to carry out a bank transaction between a payment portal (the seller) and the acquiring bank (the client), in a fast and secure way. These systems improve the interaction of Internet users, as they are faster and more accessible electronic payment systems for e-commerce.

All this is done through an API, an application programming interface that, thanks to a set of rules, allows two software applications to communicate without knowing how they are implemented.

Payment gateways are electronic payment systems provided by an e-commerce application service provider. Through these, payments and transfers are authorized safely between banks and businesses, whether traditional or electronic, or with a physical and online presence simultaneously.

A payment gateway is what keeps the payment ecosystem running smoothly, as it enables online payments for consumers and businesses through a technology that transfers data from the seller to the customer.

How do API payment gateways work?

The payment gateway performs a series of tasks to process the transaction. When a customer places an order on the website by entering their card details, the customer’s web browser encrypts the information that reaches the seller’s web server. The data is encrypted using Secure Socket Layer (SSL) or Transport Layer Security.

The details of the transaction are forwarded by the seller to their e-commerce payment solutions, where the details of their sellers’ accounts can be found. This connection is encrypted using SSL. 

In this way, the payment gateway API receives the transaction information and forwards the information to the seller’s bank, which, in turn, to obtain authorization, sends the transaction information to the one who issued the customer’s credit card. This is simple since the bank sends a response to the payment gateway by using a code. In addition to approving or rejecting the destination of the payment, the code is used to include the information about why the transaction failed, such as insufficient funds.

Some payment gateways are simply a way to load cards, with fees that charge the seller between 1.4% and 3.5%, without monthly fees. However, if you have a merchant account, the processing fees are reduced to exchange fees, which are usually between 0.10% and 20% per transaction and include monthly fees.

For a lower sales volume, a simple payment gateway will be the most effective option in the short term, as monthly fees can lower the turnover more than processing fees. However, once the sales volume reaches a critical threshold, it is more economical to pay a monthly fee for trade processing with exchange fees.

You will see that several of the best payment gateways provide both options, or some other advantage over the field. This could be anything, from reduced processing fees for certain cards to direct integration in the accounting software.

Benefits of an online payment API

It is not always easy to imagine the benefits of applying new technologies, as they are sometimes outside the comfort zone you may find yourself in.  Therefore, here are 5 advantages of applying a payment gateway api:

  • Customer loyalty.  Online payment APIs ease the way in which money transactions are made, which makes the customer feel more comfortable. This way, they will choose your company over others.
  • Increased security. Another important point that customers will take into account is that the information that is handled between applications through this modality is quite secure, since end-to-end encryption can be applied. It is also possible to choose what information to ask for and what not to ask for, for the customer’s convenience.
  • Increased sales or business opportunities. Due to the ease and convenience of the payment method, people will be much more willing to buy thanks to an API for online payments.
  • Faster payments. By implementing this interface, the buyer will be able to reduce the time it takes to make a purchase.
  • Lower maintenance costs. Without an online payment API, the application would be limited and time-consuming to develop and maintain. By using this technology, you will not have to worry about maintenance costs.
