<p>Our current location may be <a href="#fetching-nearby-users-and-geogroups">advertised to other users</a> using <a href="/method/contacts.getLocated">contacts.getLocated</a>: in this case the <code>self_expires</code> flag <strong>must always be set</strong>.</p>

<p>Our current location may be <a href="#fetching-nearby-users-and-geogroups">advertised to other users</a> using <a href="/method/contacts.getLocated">contacts.getLocated</a>: in this case the <code>self_expires</code> flag <strong>must always be set</strong>. </p>
|
||||
<p>Note that if the current user is already advertising their location using the <a href="/api/business#location">Telegram Business location feature »</a> (even without a <code>geo_point</code>, just with a textual <code>address</code>), the method will return a <code>BUSINESS_ADDRESS_ACTIVE</code> error, indicating that the location may only be changed (or removed) using <a href="/method/account.updateBusinessLocation">account.updateBusinessLocation »</a>, instead of <a href="/method/contacts.getLocated">contacts.getLocated</a>. </p>
|
||||
<p>This flag is used to specify the expiration TTL of the passed geolocation (i.e. the geolocation will expire after <code>self_expires</code> seconds); pass <code>0x7fffffff</code> to disable expiry, 0 to make the current geolocation private. </p>
|
||||
<p>The method will also return a list of nearby users and chats, but only if the passed expiration TTL is not equal to zero.<br>
|
||||
Users may still fetch nearby users and chats without making their geolocation public by simply not setting the flag, see <a href="#fetching-nearby-users-and-geogroups">here »</a> for more info. </p>
