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>.
