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.
So, we wrote our own.
It is a standard WordPress Plugin. All you need to do is unzip the file to your plugins directory, or use the zip file upload feature. Once you’ve installed it, simply activate. There are no special settings or anything else you need to do.
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>

This plugin adds a shortcode to easily insert into posts and pages the javascript code required to embed an InfusionSoft web form.

Version 2.0 adds support for Personal Access Tokens (PAT) and Service Account Keys (SAK), which replace the Legacy API Key.
Add one of these seven types of email list-builders to your WordPress website:
<ul>
<li>
Popup Opt-In Forms: Prompt your visitors to opt in without annoying them. You can set Keap’s popup opt-in forms to appear automatically after a specific amount of time, after visitors reach a particular point on your page, or even after visitors leave a comment or make a purchase.
</li>
<li>
Slide-In Opt-In Forms: The slide-in form is the pop-up’s smooth, subtle cousin. It slides in at the bottom of your visitor’s screen, and can be set to appear after a specific time or at a specific point on the page.
</li>
<li>
Widget Opt-In Forms: Use widget forms to create attractive opt-in forms for your sidebar, footer, or any other widget-friendly areas on your site.
</li>
<li>
Protected Content Opt-In Forms: Offering valuable content in exchange for an email address is one of the most effective ways to grow your email list. Protected content forms allow you to offer content your visitors can “unlock” by opting in.
</li>
<li>
Below Content Opt-In Forms: You can use “Below Content” forms to place an opt-in opportunity at the end of your blog posts or pages. Visitors who have read an entire post are highly engaged, so this is an effective way to turn that engagement into a conversion.
</li>
<li>
Inline Opt-In Forms: Want to insert an opt-in form in the middle of a blog post, rather than the end? Inline forms make it easy. You can display these forms virtually anywhere you’d like on any post or page on your website.
</li>
<li>
Notification/Opt-In Bar: Increase your opt-ins, announce your promotions and drive traffic to the pages of your choice with our attention grabbing top-of-page banner.
</li>
</ul>
You can find out how all of your opt-in forms are performing right inside your Keap dashboard. We provide elegant visualizations of your conversion rates, impressions, subscriber counts, and more, so you can track your performance at a glance.
You can also run split tests with Keap’s built-in split testing feature to discover what resonates with your audience and maximize your conversion rates.
