Install this plugin to turn your WP installation into a proxy service to connect your WordPress plugins to Infusionsoft using their Oauth API. 
This plugin was created to create an Oauth connect for FormLift and is now being released for global use for other developers.
This plugin is only for developers who plan on distributing their own plugins among the WordPress community with the need of connecting those plugins via Oauth to Infusionsoft.
Because of the limitations of Oauth, a proxy server is needed to keep your Infusionsoft Developer App’s client_id and client_secret protected as you do not want to place those in your 
plugins files as that could create a massive breach of security, and Infusionsoft might revoke your developer priviledges.
So, follow the setup procedure on <a href="https://oauth.formlift.net" rel="nofollow ugc">This Page</a> to setup your plugin to use this plugin on your proxy site to connect to Infusiosnoft.
To see how to integrate this with your WordPress plugins, visit the plugin homepage at <a href="https://oauth.formlift.net" rel="nofollow ugc">oauth.formlift.net</a>.

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.
