Joomla Extensions Selling and Validating Guide with Digicom Release System

Step 1:

Add update server info to your extensions installation mainfest xml.

Change name="Notifly Update Site", ##YOUR_PRODUCT_ID## with your info

Step 2

Check the config.xml and add the license part in your component or plugin. in this example we have shown the component system.

Step 3

check the file plg_system.php. this is your joomla system plugin, you can do it anyhow. But what you have to do is: add your license info to _update_sites table. follow the code, it shows how you need to store it on db.

Thank you
