Pull your contacts from highrise. Use this and the last post to do a one or two-way sync. More to come on this.

$highrise_url = 'http://yoururl.highrisehq.com'; // your highrise url, e.g. http://yourcompany.highrisehq.com
$api_token = ''; // your highrise api token; can be found under My Info
$task_assignee_user_id = ''; // user id of the highrise user who gets the task assigned

$curl = curl_init($highrise_url.'/people.xml');
curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);
curl_setopt($curl,CURLOPT_USERPWD,$api_token.':x'); //Username (api token, fake password as per Highrise api)

curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,0);
curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,0);

$xml = curl_exec($curl);
curl_close($curl);

//Parse XML
$people = simplexml_load_string($xml);

//var_dump($people->person);

foreach ($people->person as $person )
{
	//var_dump($person->{first-name});
	echo "Name: ".$person->{'first-name'}.' '.$person->{'last-name'}."\n";
