anonymous lead id

This is a known omission from the REST API. You can do it using the SOAP API (I forget the name of the corresponding method, but you should find it easily in the docs).

What data are you adding to the anonymous lead, though? Are you sure you want to only let the first 10,000 visitors each day get this data?  How is it actionable? Perhaps there is another, more scalable way to augment the lead data.

Hi Vu,

It seems Sanford has run into this problem, as have I.   This limitation lead to me using the SOAP API's 'getLead' function using the 'COOKIE' identifier.

Here's a test SOAP API script using the PHP helper library that grabs the MKTO Lead Id using the Cookie Id.   (the script will need some light edits before testing)

[code example start]

require_once('marketo_api.php');

$user_id = MKTO_USER_ID;

$encryption_key = MKTO_ENC_KEY;

$soap_endpoint = MKTO_SOAP_ENDPOINT;

//Connecting to Marketo

$marketo_client = new mktSampleMktowsClient($user_id, $encryption_key, $soap_endpoint);

if (empty($marketo_client)) echo "Error loading fpSDK!";

//not sure on spec. this is a placeholder

$mktoCookie = COOKIE VALUE HERE

echo $mktoCookie;

$checkLead = $marketo_client->getLead('COOKIE', $mktoCookie);

/* debuggin

echo 'checkLead:<pre>';

print_r($checkLead);

echo'</pre><br /><br />';

*/

$leadRecord = $checkLead->result->leadRecordList->leadRecord;

/* debuggin

echo 'leadRecord:<pre>';

print_r($leadRecord);

echo'</pre><br /><br />';

*/

if ($checkLead == null) {

  // DO ERROR HANDLING HERE!

  echo 'Record Does Not Exist';

  exit(1);

} else {

$leadId = $leadRecord->Id;

print_r($leadId);

}

[code example end]
