One of the issues with stock WordPress is that it tends to not like having Javascript in general and linking to an external Javascript file in specific inside of posts or pages. This is problematic for people who are integrating InfusionSoft and WordPress. We tried to find a good solution for this, but failed to find any good plugins which would be suited for the task.

To embed an InfusionSoft web form into a post or page, use the following short code:
<pre><code>[infusionsoft_form src="<Your form's url>"]
</code></pre>
