Upgrading Educational Modals, v2 to v4


Affirm Educational Modals are pop-up modal windows that appear when a customer clicks on Affirm’s Promotional Messaging, and which inform your customer of how fundamentally different and more customer-friendly Affirm financing is.  These modals can be easily co-branded.

Our latest version of Educational Modals will contain a powerful new tool - Affirm Prequalification.  Prequalification is a new feature that allows your customers to discover how much they qualify to spend with Affirm on your site early in their shopping process.  This simple tool lets your customers shop with confidence. Shoppers who leveraged Prequalification during the feature beta program spent an average of up to 30% more per transaction - on top of the existing Affirm AOV lift.

This article is meant for Affirm merchants who have integrated their promos between September 2016 and , and who would be using our legacy promos (v2).

Upgrading to the latest version of Affirm Educational Modals will enable the following:

  • Simplified integration
    • Promotional Messaging and Educational Modals are configured with a single element and promo ID.
  • Prequalification
    • Using our latest promos will allow us to add Prequalification to your Educational Modals


To upgrade to v4:

  1. Verify your upgrade steps.
  2. Make sure all Promotional Messaging placements are using the latest embed code.
  3. Reach out to Affirm staff to have Prequalification enabled for your account.
  4. Customize your Monthly Payment Messaging with a Prequalification-specific call to action.

How do I know if I'm using legacy Educational Modals (v2)?


There may be an element on your page for our 'as low as' promotional messaging that resembles this:

<p class="affirm-product-modal" data-modal-id="ABJF582KFOQ8DFK"...>

You may also have banners that are similar to this:

<p class="affirm-product-modal" data-modal-id="ABJF582KFOQ8DFK"...><p class="affirm-as-low-as"..></p></p>

The Javscript setup of Promos v2 is not unique, as it's shared with all subsequent versions. Therefore, you should rely on the above HTML identifiers to see if there's any work required to upgrade.

(search your page's source code for '_affirm_config' and you should find it)

  _affirm_config = {
    public_api_key:  "XXXXXXXXXXXXXXX",
    script:          ""
  (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 script to point to Affirm production environment.

Replace HTML


<p class="affirm-product-modal" data-modal-id="ABJF582KFOQ8DFK"...>

You can update the properties of the existing HTML element:

1. Change the 'data-modal-id' attribute to 'data-promo-id'
2. Update the value of 'data-promo-id' to the default Promo ID, 'promo_set_default' (if you haven't received another one from your Client Success Manager).


<p class="affirm-product-modal" data-promo-id="promo_set_default"...>
As-low-as + Modals

If you had to setup Affirm Promos with an 'affirm-product-modal' element wrapping the 'affirm-as-low-as-' element, you can now just make it one single 'affirm-as-low-as' element:


<p class="affirm-product-modal" data-modal-id="ABJF582KFOQ8DFK"...><p class="affirm-as-low-as" data-promo-id="ABJF582KFOQ8DDF"..></p></p>

You can update the properties of the existing HTML element:

1. Remove the outer 'affirm-product-modal' element
2. Update the value of 'data-promo-id' to the default Promo ID, 'promo_set_default' (if you haven't received another one from your Client Success Manager).


<a class="affirm-as-low-as" data-amount="50000" data-promo-id="promo_set_default">

Have Prequalification enabled for your account

An Affirm staff member can enable Prequalification for your account, just reach out to your Affirm contact via email to get the process started.

Please specify:

  1. Name of Promo IDs that you'd like Prequalification to be available through (e.g., we can use the above 'promo_set_default'). We can generate a new Promo ID as well.
  2. (optional) Which Prequalification call to action to use in place of the default 'Learn more'.
  3. (if using MFP) Specify which financing program Prequalification should attempt to use.

If you were provided a new Promo ID where Prequalification is enabled, you can enter that Promo ID into your HTML embed code like in the examples above.

Customize promotional messaging, if desired

Prequalification-specific Monthly Payment Messaging ("As Low As")

The default call to action in Affirm Monthly Payment Messaging is 'Learn more'. The addition of Prequalification to our Educational Modals will  can have the "Starting your at $10/mo with Affirm.  Monthly Payment Messaging that is more specific to Prequalification. 


  • "Starting at $10 a month with Affirm. Prequalify now"
  • "Starting at $10 a month with Affirm. See if you prequalify"

In order to setup this type of messaging, there are two main steps:

1. Inform your Affirm Client Success Manager that you'd like the Prequalification call to action added to your Monthly Payment Messaging. 

Your Affirm contact will add the new call to action (e.g., "Prequalify now") to a given Promo ID and communicate that to your team. You'll then use that specific Promo ID anywhere that you want this call to action to appear in the Monthly Payment Messaging.

2. Remove the default 'Learn more' call to action.

The 'Learn more' call to action is always appended by default, but it can be removed by setting the Monthly Payment Messaging HTML element's 'data-learnmore-show' attribute to 'false'.

For example:
<span class="affirm-as-low-as" data-promo-id="promo_set_defaul" data-learnmore-show="false"></span>

With the new call to action being added by the Prequalification-specific Promo ID, and the default 'Learn more' removed, the Monthly Payment Messaging will now appear as expected.

Exclude Prequalification from certain Educational Modals, if desired

Affirm Prequalification is enabled in Educational Modals when a Prequalification-enabled Promo ID is specified in the Monthly Payment Messaging's HTML embed code.

For example, 'promo_set_prequal' is setup with Prequalification enabled, and 'promo_set_default' does not have Prequalificaiton enabled, we should use 'promo_set_default' as the Promo ID anywhere that Prequalification messaging shouldn't be present.

Please work with your Client Success Manager to ensure that you have all the Educational Modal varients you'll need on your pages.
