You can either add '?tkbl_campaign_id=CAMPAIGN_ID_HERE' or
'?campaign_tags=CAMPAIGN_TAG_HERE' and append this to the end of your website URL.
The ID is the unique numeric identifier for each campaign, and it can be found in the URL or under the campaign’s name in the Campaigns tab. The tags can be found within the specific campaign’s Details page (above the thumbnail previews, near the incentives).
