Tuesday’s Tip: Auto-apply a Promo Code in Infusionsoft

Infusionsoft® gives you the ability to offer promo codes to your customers. To make it easier on your customers and to simplify the checkout process, you can add a snippet of JavaScript to your order form to automatically apply a promo code.

To use this JavaScript, replace YOUR-PROMO-CODE with the promo code you want to be applied. Add this JavaScript to the Custom Header HTML area for your order form:

<script type="text/javascript">
// <![CDATA[
jQuery( document ).ready(function() {
// ]]>

When your customers open the order form, the promo code will be applied automatically as soon as the page finishes loading.


  1. jQuery to save the day! While there is nothing wrong with this code, I generally prefer:


    It’s 6 and 1/2.

    • Thanks for the input! As you said, it is a matter of preference; both options give the same results.

      We chose to go with [0] for performance reasons. Using :first is slower than using [0] (see: http://jsperf.com/jquery-first-vs-first-vs-eq-0-vs-0/9), although I doubt it would make a noticeable difference to the customer in this situation.

      • Yes indeed it is speedier. I as well doubt it wouldn’t be a noticeable difference in speed but who knows, there might be someone out there on a “jitter bug” and they need every CPU cycle they can get!
