Hi @famous,

anything directly related to URL for bp is listed here:

In most case, you can built a link by array, which generally extend pre existing parameters. It’s very variable and depend where and how the link shoud work.

Here some exemple snippets to add a link to a member’s profile.

/* add external link on buddy menu bar */
function bpfr_menubar_link() {
global $bp;

if ( !is_user_logged_in() )
    return false;

$link = bp_get_loggedin_user_link();

	$bp->bp_nav[$slug] = array(
			'name'                    => 'View my profile',
			'slug'                    => 'super_link',
			'link'                    => $link,
			'css_id'                  => 'super-link',	
			'position'                => 20
		);
}
add_action( 'bp_core_new_nav_item', 'bpfr_menubar_link', 999 );

/* link to profile on SWA page */
function goto_my_profile_tab() {
  if ( !is_user_logged_in() )
    return false;

  if ( bp_is_active( 'xprofile' ) )

    echo '<li><a href="'. bp_get_loggedin_user_link() .'">View my profile</a></li>';
  
}
add_action( 'bp_activity_type_tabs', 'goto_my_profile_tab' ); // SWA page
add_action( 'bp_members_directory_member_types', 'goto_my_profile_tab' ); // members directory page

/* shortcode linking to profile [xyz] */
function bpfr_link_to_profile() {	
return '<a href="'. bp_get_loggedin_user_link() .'">View my profile</a>';			
}
add_shortcode( 'xyz', 'bpfr_link_to_profile' );

Another technique for groups here.

In hope this will help you to go further.
