Advanced javascript/ pixel usage

This is a list of exposed javascript functions from the LeadBoxer tracking pixel. 

ot_uid()
Returns the LeadBoxer user ID that represents the user 
ot_sid()
Returns an internal ID that identifies the current session


Adding properties on page load

The LeadBoxer tracking script library, once loaded, will immediately check for a function called "ot_onload". This is a hidden function that if defined, gets called. This function needs to be loaded before the script itself and needs to execute ot_log_state() - to actually append all data before the default request to our logging servers is made. 

The function needs to be in the html of the page, or if loaded externally, needs to be placed before the loading of Leadboxer script / pixel. 

A simple example looks like this:

<script type="text/javascript"> 
function ot_onload() {
  // define variables
  var CustomerId = "12345";
  var CustomerType = "Reseller";

  // add variables to map (_otmap)
  _otmap.put("Customer ID", CustomerId);  
  _otmap.put("Customer Type", CustomerType);

  ot_log_state();
}
</script>

Above example will add 2 additional properties to the lead or customer custom fields when the page loads.

Reminder: This function needs to be loaded before the default tracking script gets loaded.

Static version of the javascript library

The Leadboxer tracking script or pixel is served form a high availability, low latency, geo-ip based custom build Content Delivery Network. 

It also is not a static javascript, meaning the code can change based on various use-cases/ scenario's.

However, in case you really want or need to load the javascript library from your own servers or location, you can accomplish this with these 2 steps:

  1. Copy the contents of the hosted javascript to a local javascript file
  2. Replace the variable ot_t0 with a function that generates the current time in unixtime.
    For example with the  Date.now() function 
  3. Load this static javascript on your pages.
  4. Test

Make sure you regularly rerun these steps, as we make changes to our hosted version the tracking javascript often.

Important notice / disclaimer

Some portions of the LeadBoxer javascript library are dynamically generated and provide customised code for advanced features like cross-device or cross-browser tracking, auto-form tracking and other functions. Meaning that the basic tracking features will work properly, but we do not guarantee that all advanced features work as designed when using a static version of our pixel.
