From optimising transactions to reducing fees- selecting the right WooCommerce payment gateway could be a game-changer for your WooCommerce store

Are you a WooCommerce enthusiast ready to dive into the world of payment gateways and select the best fit for your business?

Choosing the right WooCommerce payment gateway in the UK is critical for increasing transaction speed, minimising costs, and providing a seamless customer experience across multiple touchpoints.

But before we dive in, let’s take a closer look at the WooCommerce market.

Recent WooCommerce data

  • WooCommerce commands a market share of around 39% of all e-commerce stores worldwide.
  • Their user base is approximately 6.3 million websites
  • According to a research on The State of WooCommerce 2024 by Store Leads, WooCommerce recorded an increase in the number of online stores by 9.6% quarter-on-quarter in 2024 Q1 and 50% year-on-year till Q1 this year.
  • The UK has 3.9% of WooCommerce stores, which is the second highest in the world.

Why is selecting the right WooCommerce payment gateway so important?

Payment gateways play a pivotal role in several areas of your business. Here are some of the reasons for being critical about choosing an appropriate platform:

Customer experience:

2024 Cart abandonment rate statistics published by Baymard, revealed that the average cart abandonment rate stands at a staggering 70.19% for e-commerce retailers. Thus, the consumer experience at checkout is vital. A well-integrated WooCommerce payment gateway not only ensures a seamless checkout process but also provides customers with multiple payment options, ranging from open banking methods to digital wallets to traditional card-based payments. The result? Satisfied customers who are likely to complete the transaction.


Different WooCommerce payment gateways have varying fee structures. If you run a high-volume business, switching to a gateway that charges less per transaction could help trim those hefty operational costs. Keep an eye on the extras that can catch you off-guard—setup fees, ongoing monthly payments, and charges for added features might just tip your budget over the edge. This is where a transparent and cost-efficient service provider like Wonderful can change the game for your business.

Safety and compliance:

Are you worried about e-commerce fraud? According to eCommerce fraud statistics of 2024, with about 43% of customers complaining of fraudulent transactions, nearly 75% of e-businesses are keen to ramp up their budgets for fraud prevention. WooCommerce payment gateways come with robust security measures and are equipped with fraud detection and prevention mechanisms. They further safeguard your business from any legal issues by ensuring you meet the required regulatory compliance.

Global expansion:

If you are a local business looking to scale beyond borders, a reliable payment gateway is an essential supporting tool. The best WooCommerce payment gateways can handle international transactions in various currencies. This is a vital pre-requisite for penetrating regional markets and catering to a large global audience.

Scalable integrations:

A payment gateway that scales with your business can handle growing transaction volumes and expanding operations effortlessly, ensuring smooth performance throughout. Seamless integration with your WooCommerce online store and other business tools like accounting software and CRM systems ensures streamlined operations and better data management.

  • Set up your account: Please provide the payment provider with the necessary information, including API keys, account credentials, and any other specific details.
  • Gateway evaluation: Before going live, it is crucial to test the payment gateway in a sandbox environment to confirm that transactions are processed accurately.

What is the WooCommerce payment gateway API?

If you are keen to add a custom payment gateway, then WooCommerce has a robust API to facilitate hassle-free integration. The API comes with unique hooks and filters for customising payment methods. Some of the key components are:

  • Classes: Extend the ‘WC_Payment_Gateway’ class to create a custom payment gateway.

How to integrate a local bank payment gateway with your WooCommerce store?

For both local and global businesses, adding a local bank payment gateway can open up new business prospects. Let’s go through the simple steps to integrate the payment gateway for a local bank with your WooCommerce store.

  • Procure API documents: First, you need to get the required API documents from your bank. This will include endpoint URLs, API keys, and all other security protocols.
  • Create a Custom Plugin: Utilise the WooCommerce Payment Gateway API to create a custom plugin that communicates with the bank's payment system. Implement the necessary methods, including init_form_fields, process_payment, and validate_fields, by extending the WC_Payment_Gateway class.
  • Verify the integration: As mentioned earlier, it’s essential to validate the integration in a sandbox environment. This allows you to check and rectify any glitches. You can seek WooCommerce support for this or connect with your bank for assistance if required.
  • Make sure you meet local regulations: To guarantee the security of sensitive payment information, it is imperative to comply with local financial regulations and security standards, including PCI-DSS compliance.
  • All set to go live: Deploy the plugin to your live WooCommerce store after satisfactory testing. Initially, supervise the transactions to guarantee that they are executed without any complications.
