How do I use placeholders in the URL?

You can use several placeholders in the plugin’s URL. The placeholders are replaced with the values of the corresponding properties and are processed by the server that hosts the plugin

This table describes the placeholders.

Placeholder	Description
{user_id}, {uid}	ID of current user
{date}	current date
{uname}	User name
{ulanguage}	ID of user language
{ulogin}	User login
{su_zid}	User timezone
{allow_desktop_notifications}	Parameter defining whether the user allows HTML5 notifications
{allow_vibration}	Parameter defining whether the user allows vibration alerts
