How To Setup Shopify Payment Gateways, Apps & Integrations

You’ve built the store. The products look great. The theme is crisp. But now you’re staring at the backend, wondering how to actually get paid and how to turn browsing visitors into paying customers.

It’s the make-or-break moment for every e-commerce entrepreneur.

Setting up the right infrastructure payment gateways that work for your region and apps that drive sales is what separates a hobby site from a revenue-generating business. This guide will walk you through exactly how to set up your financial plumbing and the essential tools you need to grow.

‍

Choosing the Right Payment Gateways

Your payment gateway is the bridge between your customer's wallet and your bank account. If this bridge is shaky, high-friction, or unavailable, you lose the sale. It is that simple.

When selecting a gateway, you aren't just looking for a way to accept money; you are looking for trust, low fees, and regional availability.

The Gold Standard: Shopify Payments

For most merchants, Shopify Payments is the first and best choice.

Why?

Because it integrates seamlessly into your dashboard and, most importantly, it waives the additional transaction fees that Shopify usually charges.

• The Benefit: If you use a third-party provider, Shopify typically charges an extra 2% transaction fee on the Basic plan. With Shopify Payments, that fee drops to 0%.
  
  
• The Experience: It keeps customers on your site during checkout, rather than redirecting them to a third-party page, which drastically reduces cart abandonment.

Third-Party Providers (2Checkout, PayPal, and More)

Not everyone can use Shopify Payments. Depending on your location whether you are in parts of Asia, the Middle East, or elsewhere you might need a third-party processor.

PayPal is the most common backup. It is trusted globally, and activating it is as simple as clicking "Activate PayPal" in your settings, which redirects you to log in and confirm your account.

However, for a robust credit card processor similar to Stripe or Shopify Payments, 2Checkout (now Verifone) is a powerful alternative. It supports a massive list of countries and payment methods, including Visa, MasterCard, and American Express.

Manual Payment Methods

Don't ignore the power of cash. In many developing markets, Cash on Delivery (COD) is king. It removes the trust barrier for new customers who might be skeptical about entering card details. You can easily set this up in Shopify to allow customers to pay when the product arrives at their doorstep.

Integrating Payment Gateways and Apps

Once you've chosen your provider, you need to connect it. This isn't just about clicking "Install", it's about configuring it correctly to ensure the money actually lands in your account.

Step-by-Step: Setting Up Your Gateway

The process is straightforward but requires precision.

1. Navigate to Settings: Go to your Shopify Admin, click Settings (bottom left), and select Payments.
   
   
2. Choose Your Path:
   
   • If Shopify Payments is available, click to activate it. You will need to provide your business details and banking information.
   • If you need a third-party provider, click "See all other providers".
     
     
3. Search and Select: Type in your desired gateway (e.g., "2Checkout" or "Authorize.net").

A Real-World Example: Setting Up 2Checkout

If you are using a provider like 2Checkout, the integration requires a few specific "handshakes" between the two platforms:

• Create the Account: You sign up on the 2Checkout/Verifone site, selecting "Dropshipping" or "Retail" as your product type.
  
  
• The Connection: You will need to copy two key pieces of information from your 2Checkout dashboard: the Merchant Code and the Secret Word.
  
  
• The Webhook: Back in Shopify, you paste these credentials. You may also need to set the "Redirect URL" to "Header Redirect" in your 2Checkout settings to ensure customers are sent back to your store after paying.
  
  
• Test Mode: Always enable "Test Mode" first. This allows you to simulate a transaction (successful and failed) to ensure the plumbing is working before you open it to the public.

Supercharging Your Store with Apps & Integrations

A store that only processes payments is a vending machine. To build a brand, you need Shopify integrations that market, convert, and retain customers.

The Shopify App Store is massive, which can be overwhelming. 

To build a "perfect store," you need to focus on two categories: 

• apps that build trust (free) &
• apps that drive action (conversions).

1. Best Free Shopify Apps

You don't need a massive budget to have a professional store. These tools are essential for any new setup:

• Judge.me: Social proof is everything. Judge.me is widely considered one of the best free Shopify apps for collecting and displaying product reviews. The free plan is generous, allowing you to send unlimited review requests. Seeing 5-star stars under a product title is often the nudge a visitor needs to buy.
  
  
• TinyIMG: Speed kills or rather, a lack of speed kills sales. Tiny IMG helps optimize your images for SEO and faster loading times. A faster site means a better Google ranking and happier mobile shoppers.
  
  
• Privy (Free Plan): Building an email list is non-negotiable. Privy’s free tier lets you create beautiful pop-ups to capture emails. Even if they don't buy today, capturing their email gives you a second chance to sell to them later.

2. Best Shopify Apps for Conversions

Once you have traffic, you need to maximize the value of every visitor. These apps are focused on increasing your Average Order Value (AOV) and conversion rate:

• Smile.io: Customer retention is cheaper than acquisition. Smile.io helps you build a loyalty program where customers earn points for purchases. It turns one-time buyers into loyal fans.
  
  
• Yotpo: While known for reviews, Yotpo’s suite of tools includes SMS marketing and visual marketing. It’s one of the best Shopify apps for conversions because it leverages user-generated content (photos of real people using your product) to build immense trust.
  
  
• OptinMonster: If you are serious about fighting cart abandonment, this is a heavy hitter. It uses "exit-intent" technology to show a special offer exactly when a user moves their mouse to leave your page. It’s a last-ditch effort to save the sale, and it works remarkably well.

3. Essential Shopify Integrations

Beyond apps, think about "integrations" connections to external platforms that power your business.

• Klaviyo: This is the industry leader for e-commerce email marketing. Unlike basic email tools, Klaviyo integrates deeply with Shopify data. You can send emails based on exactly what a customer looked at or how much they spent.
  
  
• Ship Station: If you are shipping your own products, ShipStation integrates to print labels from all major carriers (UPS, FedEx, DHL) in one place, saving you hours of copy-pasting addresses.

Final Thoughts

Building the perfect Shopify store is a game of layers. You start with the foundation: a reliable payment gateway like Shopify Payments or 2Checkout. Then, you layer on the functionality: Shopify integrations for shipping and email. Finally, you polish it with the best free Shopify apps to build trust and high-powered conversion tools to maximize revenue.

Don't get stuck in "setup paralysis." Pick your gateway, install these core apps, and launch. You can always tweak the settings later, but you can't optimize a store that isn't live.
