[UPDATED] Affirm Payment Gateway

Current Version: v2025-3-21 (release notes)

OpenCart Versions: 1.5.0.x - 4.1.0.x

To Purchase: Visit Clear Thinking or opencart.com



This extension allows you to accept payments in OpenCart via Affirm, the easy and secure way to offer microloans to your customers. Read more about how Affirm works here:

The extension will let customers choose from various loan options offered by Affirm, with clear interest rate and terms disclosures when they sign up. Loan decisions are made immediately, and the customer will know right away whether their loan was approved. Checking their eligibility won't affect their credit score.

• Upload and go — no core file modifications are necessary. The extension utilizes vQmod for OpenCart 1.5.x, ocMod for OpenCart 2.x/3.0, and Event hooks for OpenCart 4.
• Take advantage of the built-in extension updater. All that's required is to enter your current license key and click "Update".
• Modify all front-end text directly in the admin panel.
• Edit the error page HTML within the admin panel, without needing to modify a template file.
• Restrict the payment method from appearing based on order total, store, geo zone, and customer group.
• Utilize both Sandbox and Live server modes.
• Includes the ability to optionally display Affirm promotional messaging under product prices.
