Triggering API</title><shortdesc>The Location Triggering API enables a client application to create

and manage location based triggers. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Location based triggers notify a client application when a device enters

or leaves a specified geographical area. For example, an end user could set

a trigger so that their device notifies them when they are in the vicinity

of a specific train station. </p>

<p>A trigger has various attributes, including a triggering condition and

a system reaction. The triggering condition determines when the trigger is

fired. The system reaction determines how the client application is notified

when the triggering condition is met.</p>

<p>Typical use cases include:</p>

<ul>

<li><p>Creating a trigger</p></li>

<li><p>Modifying a trigger</p></li>

<li><p>Deleting a trigger</p></li>

<li><p>Handling a trigger firing event.</p></li>

</ul>

<p>For detailed information about the Location Triggering API, see the Location

Triggering API Specification document.</p>
