What Is Affirm and Why Does It Matter for Shopify Stores?
Affirm is a financial technology company providing point-of-sale installment loans for online purchases. Unlike traditional credit cards, Affirm offers transparent financing with no hidden fees, allowing customers to split purchases into monthly payments ranging from three to twelve months.
The platform serves over 14 million active consumers across more than 245,000 merchants. Stores offering BNPL options see conversion rate increases of 20-30% and average order values climb by 30-50%. When customers can break large purchases into manageable payments, perceived affordability increases dramatically, reducing purchase hesitation.
Prerequisites for Affirm Shopify Integration Setup
Before beginning the Affirm Shopify integration setup process, ensure you have:
Shopify Store Requirements:
- An active Shopify store on any paid plan
- Shopify Payments is enabled or a compatible third-party payment gateway
- Store currency set to USD (Affirm currently only supports US dollar transactions)
- Business registered in the United States
Affirm Account Requirements:
- Valid business information, including EIN or SSN
- Business bank account for settlement
- Products that comply with Affirm’s merchant policy
- Average order value is typically between $50 and $17,500
Affirm performs merchant underwriting, so approval is not automatic. The review process typically takes 1-3 business days.
Complete Affirm Shopify Integration Guide: Step-by-Step Setup
Step 1: Create Your Affirm Merchant Account
Navigate to the Affirm merchant portal and complete the merchant application. You’ll provide detailed business information, including your business structure, product categories, estimated monthly sales volume, and average order value. Affirm typically deposits funds to your bank account within 1-2 business days of customer approval.
Step 2: Access Shopify Payment Settings
Log into your Shopify admin dashboard and navigate to Settings > Payments. This is where you’ll manage all payment providers for your store.
Step 3: Add Affirm as a Payment Method
Scroll down to the “Alternative payment methods” section and click “Add payment methods.” Type “Affirm” in the search bar and select it from the provider list. Click “Activate” to begin the integration process. You’ll be redirected to Affirm’s authentication page to connect your merchant account.
Step 4: Install the Affirm App
After authentication, Shopify will redirect you back to your admin panel with a prompt to install the Affirm Payments app. Click “Install app” and grant the necessary permissions for store design, order information, product data, and customer data.
Step 5: Configure API Credentials
Within the Affirm app settings, input your API credentials from your Affirm merchant dashboard under Developer Settings. You’ll need both your Public API Key (for front-end messaging) and Private API Key (for back-end transaction processing).
Step 6: Enable Test Mode (Recommended)
Before going live, enable Affirm’s test mode to verify your integration works correctly. Use Affirm’s test credentials ([email protected], 555-555-5555) to process several test orders with different amounts.
Step 7: Add Promotional Messaging
Download the Affirm promotional messaging app from the Shopify App Store. Like other top-rated Shopify apps, this handles on-site messaging that educates customers about payment options. Configure the messaging to match your store’s branding and display on product pages, cart pages, and collection pages.
Step 8: Go Live and Monitor Performance
Once testing confirms everything works properly, disable test mode to begin accepting real transactions. Monitor your first few orders closely to ensure proper synchronization between Affirm and Shopify.
Understanding How Affirm and Shopify Work Together
The Affirm Shopify integration operates through a seamless API connection. When a customer selects Affirm at checkout:
- Checkout Initiation: Shopify sends order details to Affirm via API
- Credit Decision: Affirm performs a soft credit check and instantly approves or denies the transaction
- Loan Agreement: Approved customers review loan terms including payment schedule and APR (0-30% based on credit profile)
- Confirmation: Customer confirms the loan, and Affirm immediately pays you the full purchase amount minus merchant fees
- Order Fulfillment: The order returns to Shopify marked as paid
- Customer Repayment: The customer pays Affirm directly according to their installment schedule
This process typically takes 30-60 seconds, providing a user experience comparable to traditional credit card transactions.
Key Benefits of the Affirm and Shopify Integration
Increased Conversion Rates
Stores implementing the Affirm Shopify integration typically see conversion rate increases of 15-20%. When a $1,200 purchase becomes “4 payments of $300,” customers perceive the purchase as more affordable. The effect is particularly pronounced for products priced above $300.
Reduced Cart Abandonment
Research shows 28% fewer customers abandon carts when BNPL options are available. Affirm addresses price shock by breaking the total into manageable chunks, committing feel less daunting.
Higher Average Order Values
Customers using Affirm spend 30-50% more per transaction compared to those using traditional payment methods. This “installment payment effect” occurs because customers focus on the monthly payment amount rather than the total price.
Expanded Customer Base
Affirm opens your store to younger consumers building credit history, customers avoiding credit card debt, and those seeking interest-free financing. Whether you sell on Shopify without inventory through dropshipping or maintain your own stock, flexible payment solutions help capture more sales.
Affirm Shopify Integration Features That Drive Results
Flexible Payment Options
Customers choose payment plans that fit their budgets:
- 3-month plans: Best for moderately priced items ($200-$500)
- 6-month plans: Ideal for mid-range purchases ($500-$2,000)
- 12-month plans: Suited for higher-ticket items ($2,000+)
Interest rates vary from 0% APR (for qualified customers) to 30% APR based on creditworthiness.
Seamless Order Management
Orders appear in your Shopify admin with “Paid” status, Affirm charges display in payment details, and you receive the full purchase amount regardless of the customer’s payment plan. Refunds processed through Shopify like any other transaction, with Affirm automatically adjusting the customer’s remaining payment schedule for partial refunds.
Strategic On-Site Messaging
Display financing options throughout the shopping journey:
- Product Pages: Show specific monthly payments near the add-to-cart button
- Cart Page: Display financing options for the current cart total
- Homepage: Use banners promoting financing availability
- Collection Pages: Include category-level messaging for higher-priced products
Position messaging above the fold and near CTAs for maximum impact.
Optimizing Your Affirm Integration for Maximum Performance
Strategic Messaging Placement
The placement and content of your Affirm messaging significantly impacts results. Follow these best practices:
- Above the Fold: Ensure financing messages appear without scrolling on product pages. Many customers make purchase decisions based on immediately visible information.
- Near CTAs: Position messaging close to “Add to Cart” or “Buy Now” buttons. The proximity creates a clear connection between the action and the payment option.
- Dynamic Calculations: Enable real-time payment calculations that update based on product variants, quantities, or cart totals. Seeing exact monthly payments builds confidence.
- Mobile Optimization: Over 70% of e-commerce traffic comes from mobile devices. Verify your Affirm messaging displays correctly and remains readable on smartphones and tablets.
Setting Minimum Order Values
While Affirm technically supports purchases as low as $50, smaller transactions may not justify the merchant fees (typically 4-6% per transaction). Consider setting minimum order values for Affirm display:
- Below $100: Hide Affirm messaging
- $100-$200: Show messaging but don’t emphasize
- Above $200: Prominently feature Affirm
This strategy focuses your integration where it delivers the strongest ROI.
Educating Your Customer Service Team
Your support team needs thorough knowledge of how Affirm works to handle customer questions effectively:
- How approval decisions are made
- What happens if customers miss payments
- Refund and return policies with Affirm
- How to help customers manage their Affirm accounts
Create internal documentation covering common questions and troubleshooting steps.
Integrating Affirm With Your Payment Stack
Complementary Payment Solutions
Rather than replacing other payment methods, Affirm complements your payment stack. Consider offering:
- Affirm for installment purchases and higher-ticket items
- Shop Pay for fast, streamlined checkout experiences
- Traditional credit cards for customers who prefer one-time payments
- PayPal for buyer protection-focused shoppers
The more payment options you offer, the fewer customers you lose due to payment preferences. This is particularly valuable whether you operate a traditional inventory model or sell on Shopify without inventory through dropshipping.
Understanding Affirm vs. Other BNPL Options
While Affirm offers robust features, knowing how it compares to alternatives helps you make informed decisions:
Klarna: Offers additional features like price-drop notifications and a dedicated shopping app. Klarna’s marketing tools are more extensive, though merchant fees can be higher than Affirm.
Afterpay: Popular in fashion and beauty sectors. Afterpay exclusively offers 4 bi-weekly payments rather than monthly installments. It has stricter purchase limits but typically lower merchant fees.
Shop Pay Installments: Powered by Affirm but deeply integrated into Shopify’s ecosystem. Available only to Shopify Payments users, offering the smoothest native experience with minimal setup required.
For most Shopify merchants, Affirm offers the best balance of features, market reach, and integration quality. The platform’s transparent pricing and established reputation make it a reliable choice for stores of all sizes.
Common Troubleshooting Issues and Solutions
Affirm Not Appearing at Checkout
Navigate to Settings > Payments and verify Affirm shows as “Active” under alternative payment methods. Ensure your store currency is USD and your business address is in the United States.
Promotional Messaging Not Displaying
Verify the Affirm promotional messaging app is installed from the Shopify App Store. Check your theme settings to ensure Affirm messaging is enabled for product pages and cart.
Test Transactions Failing
Double-check your API keys in the Affirm app settings. Verify test mode is enabled in both Shopify and your Affirm merchant portal.
Orders Showing as Unpaid
This typically indicates a temporary connection problem. Check order details in both platforms to identify where the disconnect occurred. Contact Affirm merchant support to verify your webhook settings.
Refund Processing Errors
Affirm refunds must be processed through Shopify within 120 days of the original transaction. For older refunds or special circumstances, contact Affirm support directly.
Measuring the Success of Your Affirm Integration
Track these key performance indicators:
- Conversion Rate by Payment Method: Compare conversion rates for customers using Affirm versus other payment methods. Most merchants see 15-20% higher conversion rates.
- Average Order Value by Payment Method: Track whether Affirm customers spend more per transaction. Typically, AOV increases 30-50%.
- Affirm Utilization Rate: Calculate what percentage of customers choose Affirm when available. Typical utilization ranges from 10-25% depending on product category.
Use Shopify’s Analytics dashboard to create custom reports filtering by payment method. Your Affirm merchant dashboard provides additional insights on approval rates, average loan amounts, and preferred loan terms.
Best Practices for Promoting Your Affirm Integration
Simply installing Affirm won’t maximize its potential. Active promotion ensures customers know about the option and understand its benefits.
Email Marketing Campaigns
Announce your Affirm integration through email campaigns:
- Send dedicated announcements to your existing customer base
- Include financing callouts in promotional emails
- Feature Affirm prominently in abandoned cart recovery emails
- Create segments for customers who viewed high-value products
Social Media Promotion
Leverage your social channels to spread awareness:
- Create posts explaining how Affirm works
- Share customer testimonials about positive financing experiences
- Run social ads highlighting “Shop now, pay over time.”
- Use Instagram Shopping tags that mention financing availability
Content Marketing
Develop content that educates customers about flexible financing:
- Blog posts about smart financing for large purchases
- Buyer’s guides that mention payment options
- Product comparison articles that include financing calculations
- FAQ pages addressing common financing questions
The goal is to create awareness without being overly promotional. Focus on how Affirm helps customers afford what they want rather than pushing financing unnecessarily.

Frequently Asked Questions About the Affirm Shopify Integration
How Much Does the Affirm Shopify Integration Cost?
At Folio3, we understand that every business has unique integration needs.

Our team offers flexible pricing options for businesses of all sizes, from startups to enterprise-level operations.

Is the Affirm and Shopify Integration Difficult to Implement?
The basic Affirm Shopify integration process is straightforward for most store owners. You can complete the core setup in under 30 minutes by following the step-by-step process outlined in this guide.
However, maximizing the integration’s value requires strategic implementation including proper messaging positioning, theme integration, and team training. For merchants with custom themes or complex product configurations, professional implementation ensures everything works seamlessly from day one. Similar to other complex integrations like Teachable for digital products, Affirm benefits from expert setup when your store has unique requirements.
Does Affirm Work With All Shopify Payment Gateways?
Affirm functions as an alternative payment method, meaning it works alongside your existing payment gateways rather than replacing them. You can offer Affirm whether you use Shopify Payments, Stripe, PayPal, or most other payment processors. The key requirement is that your store’s primary payment gateway supports alternative payment methods.
Can I Use Affirm for International Sales?
Currently, Affirm only supports transactions in USD for US-based businesses selling to US customers. The financing application requires a US billing address and uses US credit data for approval decisions. If you operate an international store, use geolocation tools to show Affirm only to US customers while offering alternative BNPL options for other markets.
What Products or Industries Can’t Use Affirm?
Affirm maintains policies restricting specific product categories:
- Restricted Categories: Tobacco and vaping products, firearms and ammunition, gambling services, adult content, illegal substances (including most CBD products), live animals, and unlicensed services.
- Limited Eligibility: Travel and event tickets, cryptocurrency, timeshares, and specific medical procedures require special approval.
If your business operates in a gray area, consult with Affirm during the merchant application process for individual review.
