Aperçu

Ce guide vous explique les étapes d'intégration d'Affirm Lite, un produit conçu pour simplifier le processus de mise en œuvre et stimuler la conversion des clients. En seulement trois étapes clés, ce processus simple équipera votre site Web d'une expérience de paiement Affirm transparente, améliorant ainsi le parcours d'achat de vos clients.

Watch the video below for a detailed overview of the Affirm Lite customer checkout flow and the integration process:


Fonctionnalité

Affirm Lite keeps customers on your checkout page while they use Affirm to complete their purchase, functioning similarly to a widget. When a customer clicks the Affirm Lite checkout button, we display a pop-up window on the existing screen to guide them through the checkout process, resulting in the creation of an Affirm Virtual Card.

After the Affirm Virtual Card is created, card information can be transferred to the respective payment fields in these two ways:

  1. If you are using the query selectors for the Affirm Lite attributes, Affirm can autofill the card number, expiration date, and CVV fields with the Virtual Card’s information. See the Integration Steps section for details.
  2. Si le remplissage automatique n'est pas disponible, le client peut copier l'information directement à partir de la carte virtuelle et coller dans les champs correspondants.

🚧

iframe Autofill Compatibility

If your checkout page uses an iframe, browser security restrictions prevent Affirm Lite from autofilling customer information. As a result, customers must manually input their Affirm Virtual Card details by copying and pasting the information into the respective fields.

Page de secours d'Affirm Landing Page

To ensure a customer can complete their checkout even if Affirm Lite cannot identify a selector, you can use safeguards such as the Affirm Landing Page (previously Affirm Lite) fallback. You can activate this fallback by including the data-fallback-url attribute in your Affirm Lite code.

When you activate the fallback, the customer is redirected to the Affirm Landing Page to continue the checkout process. When the customer completes their purchase, we generate an Affirm Virtual Card. The customer then manually enters their Affirm Virtual Card details on your store's checkout page.

Étapes d'intégration

1. Add AFJS

To activate the Affirm object and use the broader Affirm.js SDK functionalities:

  1. Add the Affirm.js script in the <head> section of your global page.
  2. Initialize Affirm by:
    1. Adding your public API key, which authenticates your website's identity to Affirm, and
    2. Specifying the environment (sandbox or production) that you're targeting.
💻
Intégrer Affirm .js
Ouvrir la recette
<script>
var _affirm_config = {
		public_api_key: "YOUR_PUBLIC_API_KEY", /* replace with public api key */
		script: "https://cdn1-sandbox.affirm.com/js/v2/affirm.js",
		locale: "en_US",
		country_code: "USA",
	};

(function(m,g,n,d,a,e,h,c){var b=m[n]||{},k=document.createElement(e),p=document.getElementsByTagName(e)[0],l=function(a,b,c){return function(){a[b]._.push([c,arguments])}};b[d]=l(b,d,"set");var f=b[d];b[a]={};b[a]._=[];f._=[];b._=[];b[a][h]=l(b,a,h);b[c]=function(){b._.push([h,arguments])};a=0;for(c="set add save post open empty reset on off trigger ready setProduct".split(" ");a<c.length;a++)f[c[a]]=l(b,d,c[a]);a=0;for(c=["get","token","url","items"];a<c.length;a++)f[c[a]]=function(){};k.async=
  !0;k.src=g[e];p.parentNode.insertBefore(k,p);delete g[e];f(g);m[n]=b})(window,_affirm_config,"affirm","checkout","ui","script","ready","jsReady");
</script>

2. Add the Affirm Lite Code Snippet

Embed the Affirm Lite code snippet into your HTML as a button that triggers the Affirm checkout experience. Affirm Lite requires an additional checkout button on your checkout page. If you prefer not to design your own button, Affirm provides a pre-styled checkout button. For details, see the Affirm Checkout Button section.

To activate Affirm Lite successfully, you must:

  1. Embed the class "affirm-lite-checkout" within the Affirm Lite button's HTML.
  2. Include the data-total-amount-tag attribute to accurately capture and communicate your customer's checkout cart total to Affirm.
  3. Include the data-fallback-url attribute to redirect customers to Affirm Landing Page if Affirm Lite does not activate.
