Solidus Integration

Overview

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

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

The integration steps are:

  1. Install and configure the Solidus extension
  2. Add Affirm.js
  3. Add Affirm promotional messaging
  4. Review your order management functions
  5. Add the Confirmation Page function
  6. Test your integration
  7. Deploy to production

Before you begin

Before beginning integration, you should review:

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 https://sandbox.affirm.com/dashboard/#/apikeys 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 https://affirm.com/dashboard/#/apikeys.

1. Install and configure the Solidus extension

  1. Download the Solidus extension
  2. Follow these instructions to install and configure Solidus (edit Affirm.configure to add your sandbox API keys and to point to our sandbox)

2. Add Affirm.js

Add the Affirm.js embed code to the head of your global page template.

<!-- Affirm -->
<script>
 _affirm_config = {
   public_api_key:  "YOUR_PUBLIC_KEY",
   script:          "https://cdn1-sandbox.affirm.com/js/v2/affirm.js",
   session_id:      "YOUR_VISITOR_SESSION_ID"
 };
 (function(l,g,m,e,a,f,b){var d,c=l[m]||{},h=document.createElement(f),n=document.getElementsByTagName(f)[0],k=function(a,b,c){return function(){a[b]._.push([c,arguments])}};c[e]=k(c,e,"set");d=c[e];c[a]={};c[a]._=[];d._=[];c[a][b]=k(c,a,b);a=0;for(b="set add save post open empty reset on off trigger ready setProduct".split(" ");a<b.length;a++)d[b[a]]=k(c,e,b[a]);a=0;for(b=["get","token","url","items"];a<b.length;a++)d[b[a]]=function(){};h.async=!0;h.src=g[f];n.parentNode.insertBefore(h,n);delete g[f];d(g);l[m]=c})(window,_affirm_config,"affirm","checkout","ui","script","ready");
// Use your live public API Key and https://cdn1.affirm.com/js/v2/affirm.js script to point to Affirm production environment.
</script>
<!-- End Affirm -->

Be sure to use your public API key from the sandbox merchant dashboard for public_api_key and a session ID variable for the optional session_id to take advantage of additional analytics.

Your global page template is the only place where you need this embed code.

3. Add Affirm promotional messaging

Affirm promotional messaging components—monthly payment messaging and educational modals—show customers how they can use Affirm to finance their purchases. Properly placed promotional messaging helps drive increased AOV and conversion.

Adding Affirm promotional messaging is a required integration step, and you should complete it before testing your integration. Click here for information about adding Affirm promotional messaging.

4. Review your order management functions

Processing orders (authorize, void, refund, and partial refund) in Solidus updates the order status in the Affirm dashboard. While you can process orders in the dashboard, we strongly recommend using Solidus to keep order status synced with Affirm. For more information on processing orders in Solidus, refer to their documentation.

5. Add the Confirmation Page function

When a customer completes their purchase, you can send their order and product information to Affirm for A/B testing, which will help you optimize your site. Send this information by adding the Confirmation Page function to your payment confirmation page. We only require orderId, total, productId, and quantity for A/B testing.

Click here for all the Confirmation Page function parameters.

affirm.analytics.trackOrderConfirmed({
    "orderId": "T12345",
    "total": 3739
}, [{
    "productId": "SKU-1234",
    "quantity": 1
}, {
    "productId": "SKU-5678",
    "quantity": 1
}]);

Required function parameters

Order object

Parameter Type Description
orderId string Your internal unique identifier representing the order. Maximum 500 characters.
total integer The total amount of the transaction, including tax and shipping, stated in USD cents (e.g., $100 = 10000).

Product object

Parameter Type Description
productId string Your internal unique identifier representing the product, such as the SKU or an internal database identifier. Maximum 500 characters.
quantity integer The quantity of the purchased product.

6. Test your integration

After completing your integration, do a thorough testing of both your front-end and order management functions in our sandbox to ensure that everything works as expected. Click here for our recommended test plan. However, you’ll need to tailor your testing plan to your specific systems, processes, and integration.

7. Deploy to production

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 Client Success Manager to coordinate this test.

Connect to the live Affirm environment

  1. Retrieve your live API keys at https://affirm.com/dashboard/#/apikeys
  2. To connect to the live environment, edit Affirm.configure to add your live API keys and to point to our production environment

Launch to production

After you’ve connected to our live environment and we’ve tested your integration, you’re ready to deploy to your production environment and offer Affirm as a payment option to your customers.
