Install and configure Affirm on SAP Commerce

This guide walks you through configuring Affirm at checkout in SAP Commerce.


This guide describes how to integrate Affirm into your SAP Commerce platform so that you can provide Affirm as a payment option to your customers. After integrating Affirm, your SAP Commerce site will:

  • Offer Affirm as payment option on the checkout page.
  • Process Affirm charges in your order management system.
  • Display Affirm promotional messaging.


Before beginning the integration, you should review the following:


Sandbox development

You should have received an email inviting you to create an Affirm account. Click here for information about accessing your account.

Develop and test the Affirm integration in your development environment connected to our sandbox. To use our sandbox, retrieve your sandbox API keys at for use during integration.

After development and testing, you'll need to update your integration to use your live API keys, which you can find at

Integration steps

Installing Affirm on SAP Commerce requires downloading the add-on, updating localextensions.xml, running the installation command and rebuilding/updating the system.

Download add-on

  1. Add /checkout/affirm/authorise to your csrf.allowed.url.patterns property.

Update the system

After the previous step you may need to perform full initialization through SAP Commerce Administration Console (hAC) if this is the first installation of SAP Commerce.

If you have already performed full initialization then you need to update your SAP Commerce system as follows:

  1. Open web browser, go to hAC β†’ Platform β†’ Update.

  1. Select the checkboxes next to affirmpaymentcore,affirmpaymentfulfilmentprocess and affirmpaymentaddon

  1. Login with Admin credentials to backoffice.
  2. View Affirm Payments configuration

Updating Affirm Settings

Configuration options (optional)

It is possible to restrict Affirm as a payment option on the checkout page based on minimum or maximum cart totals. If you want Affirm to be displayed for all cart thresholds, this step can be skipped.

Step 1

To edit/view thresholds login to Backoffice with admin credentials and navigate to Price Settings -> Payment Modes and select affirm. Select the Administration tab and scroll down to Thresholds settings.


Step 2

To edit threshold, select the PaymentThreshold object from the list. Select True to set the minimum threshold and False to set the maximum threshold. Set the threshold in the Thresdhold amount field.


Step 3

Review your Order Management functions:

Processing orders (void, refund, and partial refund) in SAP Commerce updates the order status in the Affirm dashboard. While you can process orders in the dashboard, we strongly recommend using SAP Commerce BackOffice to keep order status synced with Affirm.

Step 4

Coordinate testing with Affirm:

Before deploying the Affirm integration to your production site, Affirm will need to test it in your development or staging environment connected to our live environment. Contact your Integration Consultant or [email protected] to coordinate this test.

Step 5

Deploy to production:

Connect to the live Affirm environment

  1. Retrieve your live API keys at
  2. Access the Affirm configuration outlined in section 2, go to WCMS β†’ Website β†’ ADMINISTRATION β†’ Affirm Config Container for CMSSite
  3. Set the Sandbox Mode to False (1) and update the Affirm Private Key (2) and Public Key with the live API keys from your dashboard. Click SAVE.

Launch to production

After yo have connected to our live environment and we have tested your integration, you are ready to deploy to your production environment and offer Affirm as a payment option to your customers!
