How to Add Payment Gateways to a WordPress Website in 7 Steps Guide
Step 1: Identify Your Payment Requirements
Before choosing a payment gateway on WordPress, consider:
✅ Are you selling physical products, digital products, or services?
✅ Do you need recurring payments (e.g., subscriptions, memberships)?
✅ Do you plan to sell only in the US or internationally?
✅ What payment methods do your customers prefer — Cards, Apple Pay, Google Pay, PayPal, ACH transfers?
✅ Do you require invoicing, tax calculations, or multi-currency support?
Understanding this step in the How to integrate payment gateway in WordPress process ensures the most suitable gateway that aligns with your business needs & target audience.
Step 2: Choose a Trusted WordPress Payment Gateway
Here are the top-rated gateways you should know about:
| Payment Gateway | Best For | Transaction Fee (Approx) | Recurring Billing | Global Payments |
|---|---|---|---|---|
| Stripe | eCommerce, SaaS, Global Payments | 2.9% + 30¢ per transaction | Yes | Yes |
| PayPal | Freelancers, Small Businesses, Global Users | 3.49% + fixed fee (varies by currency) | Limited | Yes |
| Square | Small to Medium Businesses, US-focused | 2.6% + 10¢ in-person / 2.9% + 30¢ online | Yes | Limited (US, CA, UK, AU) |
| Authorize.Net | Large Businesses, Advanced Security Needs | 2.9% + 30¢ per transaction + $25 monthly fee | Yes | Limited (Primarily US) |
| Braintree | Subscription Services, Marketplaces | 2.59% + 49¢ per transaction | Yes | Yes |
Notes:
✔️ Fees may vary for different payment methods (e.g., AMEX often has slightly higher rates)
✔️ Braintree is a PayPal company, ideal if you want advanced payment options beyond basic PayPal
✔️ Global payments availability depends on the account setup and supported countries
Our recommendation for your WordPress website: Stripe offers the best balance of seamless integration, WordPress security, and global payment options. For added customer trust, consider combining it with PayPal at checkout.
Step 3: Install the Payment Gateway Plugin in WordPress
The easiest way to integrate your chosen gateway is by installing a WordPress plugin.
Steps to Install:
- Log in to your WordPress Admin Dashboard
- Navigate to Plugins → Add New
- Search for your payment gateway plugin (e.g., “Stripe for WooCommerce”, “Square Payments”, etc.)
- Click Install Now and then Activate
Step 4: Set Up a Merchant Account & Get API Credentials
Most gateways require you to:
- Sign up for a merchant account on their platform
- Complete identity verification and compliance steps
- Obtain your API Keys, Client IDs, or Secret Keys — essential for linking your site securely
Tip: All major gateways offer both Test/Sandbox Mode and Live Mode for safe setup and testing.
Step 5: Configure the Payment Gateway in WordPress
Once the plugin is activated:
- Go to WooCommerce → Settings → Payments, or the specific plugin’s settings section
- Select the payment gateway you installed
- Enter your API keys and account credentials
- Enable the preferred payment options (Cards, Apple Pay, PayPal, etc.)
- Set currency to USD or add multi-currency options if applicable
- Customize checkout messages and success pages
- Save all changes
Step 6: Test Your Payment Gateway Integration
Before accepting real payments:
✔️ Enable Test Mode/Sandbox Mode in your payment gateway and plugin settings
✔️ Run test transactions using dummy card details provided by the gateway
✔️ Verify successful and failed payment scenarios
✔️ Confirm email notifications, order statuses, and checkout functionality
✔️ Test the mobile and desktop checkout experience
Thorough testing ensures everything works smoothly before going live.
Tip from Enstacked Team: The majority of payment failures are preventable with proper testing and updated security protocols.
