Navigating the Shopify External Payment Gateway

Introduction

Choosing the right way to accept money is one of the most important decisions a Shopify merchant makes. While Shopify Payments is the default choice for many, it is not available in every country or for every business type. This is where a Shopify external payment gateway becomes essential for maintaining a functional and profitable online store. If you want a simple way to manage which external gateways appear for each customer, consider installing [HidePay on the Shopify App Store].

Using an external provider allows you to reach customers in specific regions, support niche industries, and offer localized payment methods. At Nextools, we developed [HidePay — free to install] to help merchants manage these various options and ensure the checkout process remains organized and efficient. Managing multiple gateways correctly can be the difference between a completed sale and a frustrated customer.

This article explains how external gateways work, the fees you can expect, and how to optimize your checkout layout to maximize conversions. You will learn how to choose the right provider for your specific business needs and how to avoid common pitfalls associated with third-party integrations.

The Difference Between Direct and External Providers

Shopify categorizes credit card payment providers into two distinct groups: direct providers and external providers. Understanding the technical difference between these two is vital for the customer experience you want to create.

A direct provider allows a customer to complete their purchase without leaving your online store. The checkout remains hosted on your domain, and the customer enters their credit card details directly into the Shopify checkout fields. This creates a fluid experience that keeps the buyer focused on the final confirmation.

An external payment gateway works differently. When a customer selects an external provider at checkout, they are redirected to a secure page hosted by that third party. Once the payment is completed on the external site, the customer is sent back to your Shopify "Thank You" page. While this redirection adds a step, it is often necessary for certain security protocols or regional payment habits.

Key differences at a glance:

• Direct Providers: The checkout happens entirely on your store.
• External Providers: The customer completes the payment on a third-party website.
• Customer Perception: Direct providers generally feel more integrated, while external providers are common in markets where third-party trust is high (like PayPal).

Why Choose an External Gateway for Your Store

Merchants often assume that Shopify Payments is always the best option, but external gateways serve several critical functions that the native system cannot always match.

Regional Availability

Shopify Payments is currently available in a limited number of countries. If your business is based in a region like Brazil, South Africa, or much of Southeast Asia, you must use an external payment gateway to process credit cards. These providers understand local regulations and banking systems better than a global default might.

Industry Restrictions

Certain industries are classified as "high-risk" by traditional banks and Shopify’s primary processors. This includes sectors like supplements, gaming, or certain specialized electronics. External gateways often specialize in these industries, providing the necessary underwriting and risk management that allows these stores to stay in business.

Local Payment Preferences

In many parts of the world, credit cards are not the dominant way to pay. In the Netherlands, iDEAL is the standard. In many parts of Africa and Asia, mobile wallets are preferred. External gateways like Adyen or Oceanpayment allow you to offer hundreds of local payment methods through a single integration.

Understanding Third-Party Transaction Fees

One of the most significant factors in choosing an external gateway is the cost. When you do not use Shopify Payments, Shopify charges a "third-party transaction fee" on every order. This fee covers the cost of maintaining a secure checkout and integrating with external systems.

These fees vary based on your Shopify plan:

• Basic Shopify: 2.0% per transaction.
• Shopify: 1.0% per transaction.
• Advanced Shopify: 0.5% per transaction.

It is important to note that these fees are in addition to whatever the external payment gateway charges you for processing. For example, if your gateway charges 2.9% + $0.30 and you are on the Basic Shopify plan, your total transaction cost will be 4.9% + $0.30.

How to Calculate the Impact

To determine if an external gateway is worth the cost, calculate your effective rate. If an external provider offers a processing rate of 1.5% and you are on the Advanced plan (0.5% fee), your total cost is 2.0%. If Shopify Payments would have charged you 2.4%, the external gateway is actually the cheaper option despite the added Shopify fee.

Fee Exemptions

You are generally not charged these third-party fees if you use Shopify Payments as your primary gateway, even for other integrated methods like Shop Pay or PayPal Express. Manual payment methods, such as bank transfers or cash on delivery, also typically avoid these transaction fees.

Top External Payment Gateways for Shopify Merchants

There are over 100 credit card providers available for Shopify stores. Selecting the right one depends on your volume, location, and customer base.

Stripe

Stripe is a favorite for many developers and large-scale merchants. It is known for its robust API and excellent security features. While Stripe powers Shopify Payments, some merchants choose to use a standalone Stripe account to access advanced reporting or specific international features not available in the native Shopify integration.

PayPal

PayPal is perhaps the most recognized external provider globally. It offers both a direct experience (PayPal Express) and various external options. For many customers, seeing the PayPal logo provides a sense of security that can increase conversion rates, especially on mobile devices.

Adyen

Adyen is built for global enterprises. It supports a massive array of local payment methods and currencies. If you are a high-volume merchant selling in dozens of countries, Adyen provides a unified platform that simplifies international expansion.

Authorize.net

This is one of the oldest and most reliable names in payment processing. It is highly customizable and works well for businesses that need a dedicated merchant account and high levels of fraud protection.

Oceanpayment

For merchants targeting the Asian and Chinese markets, Oceanpayment is a strong contender. It supports over 500 alternative payment methods and provides the transparency needed for cross-border e-commerce.

Strategic Payment Gateway Management

Once you have integrated an external gateway, the work is not finished. Simply listing five or six different payment options can overwhelm a customer. Choice paralysis is a real phenomenon that leads to cart abandonment. You must manage which gateways appear and in what order.

We believe that a "Smart Checkout" approach is the best way to handle multiple providers. This means only showing the payment methods that are relevant to the specific customer at that specific moment. If a customer is in the United States, they do not need to see a European-specific gateway.

Sorting for Profit

Every payment method has a different cost to you. Some gateways charge higher percentages, while others have higher flat fees. By reordering the payment methods, you can guide customers toward the options that protect your margins. Placing the lower-fee credit card option at the top of the list can significantly impact your monthly bottom line. For step-by-step instructions on ordering and renaming options, see the HidePay guide to [Sort and Rename payment methods in the Checkout].

Protecting Your Store from Chargebacks

Some external gateways are more prone to chargebacks than others. For example, some merchants find that certain digital wallets attract more fraudulent activity. By using logic to hide specific gateways for high-risk orders or specific product categories, you can reduce your financial risk without affecting legitimate customers.

How to Optimize Checkout with Conditional Logic

Optimizing your checkout means creating rules that respond to the customer's behavior and order details. This level of control ensures a professional and efficient experience.

Geography-Based Rules

This is the most common use case for external gateways. If you sell globally, you might use one gateway for North America and another for Europe. You should set rules so that the North American gateway is hidden for European customers. For a walkthrough on creating country-based rules, consult the HidePay help article about organizing payment methods by country in the [HidePay Help Docs].

Product-Based Restrictions

Some payment providers have strict policies against certain products. If you sell a mix of standard goods and regulated items, you may need to hide certain gateways when the regulated item is in the cart. This prevents your entire payment account from being flagged or suspended for a policy violation.

Order Value Logic

For very small orders, a gateway with a high flat fee can eat up your entire profit. Conversely, for very large orders, you might prefer a gateway with a lower percentage fee but a higher flat fee. Creating rules based on the cart total allows you to always present the most cost-effective option for the business.

Customer Tagging

If you run a B2B store alongside your retail store, you likely want different payment options for your wholesale clients. You can use customer tags to show "Net 30" or bank transfer options only to your logged-in B2B customers, while keeping the standard credit card gateways visible for everyone else. The HidePay help article on [Hide Payment Options by Customer TAG] explains how to target tags when creating rules.

Configuring Your External Gateway in Shopify Admin

Setting up an external gateway is a straightforward process within your Shopify admin, but it requires attention to detail to ensure everything functions correctly.

1. Navigate to Payments: Go to your Shopify admin settings and select "Payments."
2. Choose a Provider: In the "Third-party providers" section, click to choose a provider. You can filter these by name or by the country where your business is located.
3. Enter Credentials: You will need to provide the account credentials from your chosen gateway. This usually includes a Merchant ID, an API key, or a Secret Key.
4. Enable Test Mode: Before going live, use the test mode provided by the gateway. This allows you to simulate a transaction to ensure the redirect and the "Thank You" page communication are working.
5. Deactivate Old Gateways: If you are switching from one external provider to another, ensure the old one is deactivated to avoid showing duplicate or broken options to your customers.

If you want a concise walk-through on creating rules inside the app, see the HidePay article on [How to create a payment customization].

Action Summary for Merchants:

• Review your current transaction fees in the Shopify Billing section.
• Check if your business category is supported by Shopify Payments or requires an external gateway.
• Research the local payment preferences of your top three selling countries.
• Install a management tool to sort and hide gateways based on customer location and order value.

Best Practices for Global Checkout Optimization

When using an external payment gateway, your goal should be to make the transition as smooth as possible. Since external gateways often involve a redirect, trust is the most important currency.

Use Clear Naming Conventions Do not just label a payment method with the name of the software. Instead of "Adyen," use "Credit Card / Debit Card (Adyen)." This tells the customer exactly what they are doing and reduces the "fear of the unknown" when they are redirected to a different site.

Surface Express Buttons Carefully Express checkout buttons like PayPal or Apple Pay can speed up the process, but they can also bypass your preferred gateway logic. Ensure your external gateway settings and your express button settings are aligned so that you aren't paying double fees or losing out on valuable customer data. If you need to block express buttons, refer to the HidePay help guide to [Hide the Express Checkout with HidePay].

Monitor Conversion Rates by Gateway Check your Shopify analytics regularly to see the conversion rate for each payment method. If one external gateway has a significantly higher abandonment rate, it may be due to a slow redirect or a confusing interface on the third-party site. If this happens, consider moving that gateway lower in the list or replacing it entirely.

Prioritize Performance The app you use to manage these gateways must be fast. HidePay is built on Native Shopify Functions, which means the logic runs directly within Shopify’s infrastructure. There are no external scripts that slow down your checkout page. Speed is a primary factor in checkout conversion, and using native tools ensures your external gateway strategy doesn't come at the cost of performance.

Conclusion

The Shopify external payment gateway is a powerful tool for merchants who need flexibility, global reach, or specialized processing. While it introduces third-party fees, the ability to offer local payment methods and support high-risk industries often outweighs the added cost. By understanding the difference between direct and external providers and managing them with precise rules, you can create a checkout experience that feels professional and increases your profit margins.

Key Takeaways:

• External gateways are necessary for regional support and high-risk industries.
• Shopify charges additional transaction fees (0.5%–2%) when you don't use Shopify Payments.

FAQ

Does using an external payment gateway affect my Shopify plan price?

Using an external gateway does not change your monthly Shopify subscription fee, but it does introduce additional third-party transaction fees. These fees range from 0.5% to 2.0% depending on your plan. You will still pay your gateway’s separate processing fees on top of these Shopify charges.

Why does my customer get redirected to another site to pay?

This happens because you are using an external provider rather than a direct provider. External providers host their own secure payment pages to process sensitive data. Once the transaction is authorized, the provider automatically sends the customer back to your store's confirmation page.

Can I use both Shopify Payments and an external gateway?

Yes, you can use Shopify Payments as your primary method for credit cards while also offering other external options like PayPal or regional providers. This is often the best way to avoid extra fees on most orders while still providing the flexibility your international customers need.

How can I hide an external gateway for specific products?

You can hide gateways by using an app like HidePay that utilizes Shopify Functions. You can create a rule that identifies a specific product or category in the cart and tells Shopify not to display a particular payment method for that transaction. This is helpful for staying compliant with gateway policies. For detailed steps, see the HidePay help article on [How to Hide Payment Methods by Product Tags].
