Integrate Affirm Payment Options into Your WordPress Site: Two Practical Approaches
By WordPress Experts |
Incorporating Affirm as a payment method on your WordPress platform can significantly enhance the shopping experience for your customers. This buy now, pay later service allows users to divide their purchases into smaller, scheduled payments, which many find more convenient than traditional credit card transactions.
Numerous online merchants have discovered that providing multiple payment alternatives can lead to higher conversion rates and increased revenue. While this guide focuses on implementation methods, the underlying principle remains that flexibility in payment processing often translates to improved customer satisfaction and business growth.
This comprehensive tutorial will walk you through the process of enabling Affirm payments on your WordPress website using two distinct approaches.
Understanding Affirm and Its Benefits for WordPress Sites
Affirm operates as a prominent buy now, pay later platform that enables customers to acquire products immediately while spreading payments across multiple installments over time.
The service provides various payment structures to accommodate different purchasing needs. The 'Pay in 4' option is particularly popular, dividing the total cost into four equal, interest-free payments scheduled every two weeks.
For more substantial purchases, customers may select extended monthly payment plans, though these arrangements sometimes include interest charges.
By implementing Affirm payments, you make your offerings more accessible, especially for higher-value items. A significant advantage for merchants is receiving the complete payment upfront while Affirm manages the collection process and assumes the financial risk if customers default on their payments.
With these considerations in mind, let's explore two effective methods for integrating Affirm payments into your WordPress environment.
- Method 1: Implement Affirm Payments Using WP Simple Pay (Recommended for Non-WooCommerce Sites)
- Method 2: Enable Affirm Payments for WooCommerce Using the Official Plugin

Let's begin the implementation process to enhance your payment options and potentially increase sales.
Method 1: Implement Affirm Payments Using WP Simple Pay (Recommended for Non-WooCommerce Sites)
This approach works particularly well if you need to add an Affirm payment form to your website without using WooCommerce. It's suitable for accepting donations, membership fees, content access charges, and various other payment scenarios.
The most straightforward way to process Affirm payments through forms involves using the WP Simple Pay plugin.
This solution represents a leading Stripe integration for WordPress that facilitates online payment acceptance without requiring a full shopping cart system.
The plugin features an intuitive form builder, secure payment processing capabilities, recurring payment functionality, and comprehensive support for Affirm payments.
Configuring WP Simple Pay
Begin by installing and activating the WP Simple Pay plugin on your WordPress installation.
After activation, a configuration wizard will appear on your screen. Proceed by selecting the 'Let's Get Started' option.

The subsequent step requires entering the plugin's license key, which you can locate in your account area on the WP Simple Pay website. After providing this information, select 'Activate and Continue.'

Next, you'll need to establish a connection between your Stripe account and WP Simple Pay. Stripe serves as a widely-used payment gateway that simplifies online transaction processing.
Select the 'Connect with Stripe' button to proceed with the integration.

You'll then need to log into your existing Stripe account to complete the connection. If you don't currently have a Stripe account, you can create one directly through their official website.
Following successful Stripe integration, the setup wizard will prompt you to configure email notification settings.
Here you can enable various email alerts including payment receipts, upcoming invoice notifications, and payment confirmations, while specifying the recipient email addresses.
Once you've configured these settings to your preference, select the 'Save and Continue' button.

You may now exit the setup wizard and proceed to create your first payment form.
Developing Your Affirm Payment Form
Navigate to the WP Simple Pay » Payment Forms section within your WordPress administration panel and select the 'Create Your Payment Form' option.

This action opens the template selection screen where you can choose from various pre-designed form templates by clicking the 'Use Template' button beneath your preferred option.
For demonstration purposes, we'll utilize the standard 'Payment Form' template.

You'll be directed to the 'Add New Payment Form' interface where you can begin by assigning a title and description to your form.
Next, specify your form type as 'On-site payment form.'

After completing these initial steps, navigate to the 'Payment' tab in the left-hand column.
Within this section, you can select your preferred tax collection rates from the dropdown menu under the 'Tax Collection' setting.
Subsequently, you can establish the default price for the service or product associated with this payment form.
