The minimum supported version for the JW player is 8.17.0. Prior to this version JW didn't expose enough events and data for our plugin to be able to properly collect the needed metrics. Please make sure your players are at least on this version before proceeding to the next steps.
The plugin url for the US zone is
and for EU is
Depending on your contractual agreement with us your data could be hosted in US, Europe or other zone. Make sure you use the correct plugin url otherwise your data will not be routed correctly.
The best way to add our plugin to a JW player is by adding the plugin configuration options to the JW player init options. This will ensure our plugin is set up and initialised before any important event that we might need to capture happens.
See the configuration options for some other config params you can use
for the plugin (only
apiKey is required).
You can retrieve the API key from the Watching That app.
For the rare cases when you might not be able to use the above setup we provide an alternative way:
#1. Load the plugin script
Or you can load the plugin programmatically from the same url.
#2. Start the plugin
It is important to run the code below immediately after starting the JW player or as soon as possible. If you delay starting the plugin for too long, it might miss important events that happen after the player starts and before the plugin starts.
The general start call looks like this:
playerRef parameter you can use either the instance of the JW player:
or the id you used when starting the JW player:
or the DOM element with that id:
If you're starting our plugin from within the player
onReady handler then you must let our plugin know about this:
Our plugin might never start working without setting that third parameter to
true in this scenario! This is because
wtAdTracer() function sets up its own
onReady listener but since the
ready event happens only once and it
has already happened, the plugin will most likely not be started.
When you have a CMS or complex frontend code which lets you load scripts you might be tempted to do this:
Loading the plugin only after the player is ready is an anti-pattern because by the time it's loaded and started, the plugin might miss some early player events. In other words the player will not pause and wait for the plugin to load and start, but it will move on and start the video, make ad requests, etc. Once the plugin loads and starts it will capture events from that point onward only.
The better approach would be to load the plugin independently of the player and start it in the
