Upload your IPA on a FTP. Then create a plist file with this format:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>items</key>
<array>
<dict>
<key>assets</key>
<array>
<dict>
<key>kind</key>
<string>software-package</string>
<key>url</key>
<string>https://sabisin.com/myApp.ipa</string>
</dict>
</array>
<key>metadata</key>
<dict>
<key>bundle-identifier</key>
<string>com.sabisin.myApp</string>
<key>bundle-version</key>
<string>1.0</string>
<key>kind</key>
<string>software</string>
<key>title</key>
<string>MyGame</string>
</dict>
</dict>
</array>
</dict>
</plist>
Change the url, app id and title name. Then create a simple HTML page:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fr">
<head>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />
<title>Install MyGame</title>
<style>
html, body { height:100%; }
</style>
</head>
<body>
<br/>
<div style="text-align:center;">
<h3>Install myApp</h3>
</div>
<div style="text-align:center;">
<img src="icon_57.png" border="0" align="center"></img>
</div>
<br/>
<div style="text-align:center;">
<a href="itms-services://?action=download-manifest&url=https://sabisin.com/myApp.plist">Install myApp</a>
</div>
<br/>
</body>
</html>
You must have your plist file on a https server.
