<p>To send a live geolocation, use <a href="/method/messages.sendMedia">messages.sendMedia</a> with an <a href="/constructor/inputMediaGeoLive">inputMediaGeoLive</a> <code>media</code> . </p>
<p>The <a href="/constructor/inputMediaGeoLive">inputMediaGeoLive</a> allows sending the geolocation as an <a href="/constructor/inputGeoPoint">inputGeoPoint</a> with floating point latitude and longitude, with an optional <code>accuracy_radius</code> in meters.<br>
Clients can also provide a <code>heading</code>, a direction in degrees (1-360) that can be used to indicate the direction of the user, a validity <code>period</code> for the current location, and a <code>proximity_notification_radius</code> . </p>
<p>The sent geolocation should be updated periodically using <a href="/method/messages.editMessage">messages.editMessage</a> <strong>at most</strong> every <code>period</code> seconds, in order to implement the "live" part of live geolocations. </p>
<p>To stop sharing the location, pass <a href="/constructor/inputGeoPointEmpty">inputGeoPointEmpty</a> as location and set the <code>stopped</code> flag to true in a last <a href="/method/messages.editMessage">messages.editMessage</a> call. </p>
