T-Values (Tracking Tags)
t1, t2, and t3 are optional tags you add to click URLs (or Search API requests) so you can break reporting down by campaign, placement, source, or whatever scheme you use.
They show up as columns on the Details download in Earnings Report when you set them on the click URL. The T-Values Reporting API still serves hourly JSON for older setups.
Tags do not change whether a click is valid, expired, or stale. See Click Validation.

How to Attach Tags
Use t1, t2, and t3 on the Talroo click URL: Search url fields, XML <url> values, and widget links.
XML and Affiliate-Style Click URLs
Append them to the click URL Talroo gives you. Don't strip the tracking keys that are already there.
Original URL:
https://www.jobs2careers.com/click.php?jid=abc123&ri=def456
With tags:
https://www.jobs2careers.com/click.php?jid=abc123&ri=def456&t1=campaign_name&t2=traffic_source&t3=keyword_variant
If you also use rdr, URL-encode both values. See RDR (Redirect).
Search API Publishers
Pass t1, t2, and t3 on GET search.php so the job url fields inherit them. See API Integration.
Earnings Report (TAP)
For filters, feed chips, and the Downloads column, see Earnings Report.
Pick a naming convention early (snake_case, fixed campaign IDs) and stick with it. Don't put a unique value on every click in t3. That makes the export noisy.
