Shopify Payment Gateway Integration Services Guide

**How to Integrate Payment Gateway in Shopify Store.**

Online stores need a safe and simple way to collect payments. That’s where payment gateways come in. If you run a Shopify store, adding a gateway is one of your most important setup steps. In this guide, we’ll walk you through everything about Shopify Payment Gateway Integration Services—from choosing a provider to going live.

What Is a Payment Gateway and Why Is It Needed?

A payment gateway acts as a link between your Shopify store and the bank. It lets your customers pay through cards, wallets, UPI, and more. Without a gateway, you can’t accept online payments.

It’s not just about receiving money. A payment gateway also protects transactions, keeps payment data secure, and processes refunds.

How Payment Gateways Work in Shopify

Shopify has a simple system to connect with different payment services. It supports its own gateway—Shopify Payments—as well as third-party ones like PayPal, Razorpay, Stripe, and others.

Each payment made by a buyer is processed through the selected gateway. Then, the funds go to your merchant account after processing.

You’ll find these gateways under Settings → Payments in your Shopify dashboard.

Types of Payment Gateways for Shopify Stores

There are two main types of gateways Shopify supports:

1. Shopify Payments

Built-in payment solution from Shopify
Supports credit cards, debit cards, and digital wallets
Available in selected countries
No extra transaction fees (except credit card fees)

2. Third-party Payment Gateways

These include:

Razorpay – Preferred in India
PayPal – Popular worldwide
Stripe – Accepted in many countries
Authorize.net – Great for US merchants
PayU – Common in South Asia

You can pick based on your region, currency, and customer preference.

Things You Need Before Adding a Payment Gateway

Before setting up a payment gateway, keep the following ready:

A Shopify account and live store
A business bank account to receive payments
A valid GST number (for Indian merchants)
Basic documents for KYC verification (PAN, Aadhar, etc.)
A secured site with SSL certificate (Shopify provides this)

Once you have this, you can begin the setup.

Step-by-Step Guide: Shopify Payment Gateway Integration

Let’s now go through how to set up a gateway on Shopify.

Step 1: Log in to Your Shopify Admin

Visit your Shopify dashboard with your admin credentials.

Step 2: Go to Settings → Payments

On the bottom left, click Settings, then select Payments.

Step 3: Choose a Payment Gateway

For Shopify Payments, click “Activate Shopify Payments.”
For others like PayPal or Razorpay, click “Add payment methods.”

Step 4: Fill in the Required Details

You’ll need to enter merchant credentials. These usually include:

● Merchant ID

● Secret Key

● API Key or Webhook URLs

These are provided by your payment gateway account.

Step 5: Activate the Gateway

After adding the details, click Activate or Save. Your gateway is now connected.

Testing Your Payment Gateway

Before accepting live payments, test the process using Shopify’s test mode.

1. Enable test mode from your payment settings

2. Use dummy credit card details from Shopify’s test data

3. Place a fake order to check success and failure cases

4. Cancel the order to see how refunds work

This helps you avoid issues before real transactions begin.

How to Add Razorpay to Shopify

Razorpay is one of the top choices for Indian sellers. Here’s how to add it:

Create a Razorpay account
From Shopify Admin, go to Settings → Payments
Select Third-party providers and search for Razorpay
Enter the Key ID and Key Secret from your Razorpay dashboard
Click Activate

Razorpay supports UPI, wallets, net banking, and cards.

Common Payment Gateway Issues and Fixes

Sometimes, things don’t work as planned. Here’s how to handle common problems:

Gateway Not Showing Up

Check if it’s available in your country
Make sure your store is on a paid plan
Confirm if the gateway supports your currency

Transaction Fails

Check API keys for errors
Verify with the gateway provider if services are down
Make sure test mode is turned off for live payments

Payment Option Missing at Checkout

Recheck integration steps
Enable supported payment methods from the gateway dashboard
Review currency settings in your Shopify store

Which Gateway Should You Choose?

This depends on:

Your target country
Preferred payment modes of your customers
Transaction fees per payment
Customer support quality

If you’re in India, Razorpay, Cashfree, and PayU are reliable. If your buyers are global, try PayPal or Stripe.

Multiple Gateways? Yes, It’s Possible

You can add more than one payment gateway. For example, Shopify Payments for card processing and PayPal for wallets.

Just go to Settings → Payments and repeat the steps for each gateway.

Giving your customers more payment options reduces checkout failures.
