Payment Gateways: How to Add One to Your Website

Whatever your line of business, the chances are that you’ll need the ability to accept online payments – for products you sell on your website, services you provide or payments to your SaaS platform. You’ll want to offer your clients or customers a secure, convenient and easy payment experience and to do this, you’ll need to integrate a payment gateway with your website.

Adding a payment gateway to a WordPress, Wix, or GoDaddy website is a straightforward process involving a number of steps, and once it’s completed, your business will be able to get paid by customers on your website or app safely and securely.

What is a payment gateway?

A payment gateway is an intermediary service that facilitates the authorization and processing of online payments, enabling your customers to pay you using debit or credit cards, bank transfers or digital wallets, providing security, data encryption and regulatory compliance as required. Some payment gateways also enable you to send electronic invoices and make payment requests.

How does a payment gateway work?

If you want to receive payments from customers all over the world, you need to get a payment gateway up and running. This will ensure safe, secure payments which fulfil regulatory requirements and that you automatically receive your FIRA/FIRS/NOC.

Although a transaction through a payment gateway only takes a few seconds, this is the process involved:

• Once the customer has entered their payment details, these are verified for validity and to check that the customer has the necessary funds to make the transaction
• The necessary data for the transaction is encrypted and then transmitted
• The transaction is analyzed by advanced fraud detection tools, and red flags such as unusually high transactions or high-risk locations are identified
• Once the transaction has been approved, the gateway facilitates the settlement of funds to the merchant’s bank account

In most cases, how to add payment gateway in a website comes down to choosing the right provider, setting up your merchant account, connecting the gateway to your site, testing the checkout flow, and making sure payments work securely for your customers. The section below explains that process in a clear way so you can understand what is needed before you start implementation.

Choosing your payment gateway

Your choice of payment gateway will depend upon a number of factors, such as the compatibility with your ecommerce platform, types of payment accepted, the geographic reach of the gateway, fees and charges, whether they offer local receiving accounts, and having an adequate level of security. Work out which provider will best align with the way you operate, and decide between hosted, API and plugin.

Setting up a merchant account

For some of the e-commerce payment gateways, such as Stripe, you’ll need to set up a merchant account. This is a bank account that holds payments before they are finally settled. Some payment gateways provide built-in merchant account services. Others, like Payoneer, do not require one.

Receive your API keys

API keys are unique identifiers that you need to connect your website to the payment gateway. Their purpose is to ensure secure communication between your website and the payment gateway’s server.

Integrate the payment gateway into your website

The exact step-by-step process will vary between payment gateways and website platforms, and might include plugins or extensions, or in rare cases, even manually adding code to your website. However, this process is typically more streamlined with leading gateway providers.

Test that the integration has worked

Do not go live until you’ve made a test run in the ‘sandbox’ or testing environment of the payment gateway. This will allow you to fix any issues before you process real transactions.

Go live

Once live, your customers can start processing transactions. Continue to monitor performance using the payment gateway dashboard.
