Overview

Including and initializing Affirm.js

Include the affirm.js script to the head of your global page template.

To create an instance of Affirm, you must pass your public API key and the environment you are pointing to. The Affirm object is your entry point into the rest of the Affirm.js SDK.

Your Affirm public API key is required when calling this function because it identifies your website to Affirm.

When you’re ready to accept live transactions, replace the sandbox key with your live key in production as well as the environment URL.

<script>
const _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=
