This plugin is an improvement to the current WordPress plugin installation methods. It allows you to install one or more plugins simply by typing their names or download URLs in a textarea.
All credit goes to improvingtheweb. This plugin is only a modification of <a href="https://wordpress.org/extend/plugins/improved-plugin-installation/" rel="ugc">Improved Plugin Installation</a>. The idea was to run the original plugin in the newer versions of WordPress. That’s it. Also, we cut off the bookmarklet feature.
Thank you very much for the contributions: <a href="https://profiles.wordpress.org/drewapicture/" rel="nofollow ugc">drewapicture</a>
Example
The installation form will accept any of these inputs:
<ul>
<li>Contact Form 7</li>
<li>https://wordpress.org/extend/plugins/contact-form-7/</li>
<li>https://downloads.wordpress.org/plugin/contact-form-7.3.3.2.zip</li>
</ul>
Plugins don’t need to be hosted at wordpress.org. As long as you use the direct download URL, third party plugins will install without a problem.

Kyght

Tracks the distribution of your installable products. The plugin provides an ajax API to accept installation registrations & usage data. Also provides a mechanism for pushing product upgrades to clients. Custom build tags can also be used to track clients with customized products and push custom upgrades to these clients.
Plugin REST API 
 http://www.yoursite.com/wp-admin/admin-ajax.php
<pre><code>Actions:
 regupdate - Adds\Updates a registration record
 useapp - Updates product\version usage and registered client use
 upgrade - Checks for a product upgrade with a higher version number

Note: Product and Registration records are automatically added\updated via inbound API calls. Only Upgrades are added via the Admin console.

Example (.Net API call to register a client)

 **Registration**
 var response = HttpHelper.Post(URL, new NameValueCollection() {
 { "action", "regupdate" }, 
 { "sky", SecretKey }, //Secret ID must match ID in your WordPress|Settings|InstallTracker 
 { "product", Product },
 { "ver", Version },
 { "custom", Custom },

 { "trackid", RegID }, //TrackID from previous registration to allow updates, blank for new
 { "key", key }, //GUID generated by your installation (Format: 00000000-0000-0000-0000-000000000000 )
 { "name", name },
 { "email", email },
 { "phone", phone },
 { "contact", contact },
 { "addr", address },
 { "city", city },
 { "state", state },
 { "zipcode", zipcode}
 }); 

 var str = System.Text.Encoding.Default.GetString(response);
 if (str != null && str.Equals("0")) return false; //Secret key might not match
 var outObject = JsonConvert.DeserializeObject<Registration>(str);
 if (outObject.valid == "TRUE")
 {
 RegID = outObject.regID; //Returned Registration ID for future updates
 return true;
 } 

 **Usage**
 var pars = new NameValueCollection() {
 { "action", "useapp" }, 
 { "sky", SecretKey }, 
 { "product", Product },
 { "ver", Version },
 { "custom", Custom },

 { "trackid", RegID }, //TrackID from previous registration (optional)
 { "key", key } //GUID generated by your installation (optional)
 };


 **Upgrade**
 var pars = new NameValueCollection() {
 { "action", "upgrade" }, 
 { "sky", SecretKey }, 
 { "product", Product },
 { "ver", Version },
 { "custom", Custom },
 };
