Mistake: clickid passed to offer but never returned

Mistake: clickid passed to offer but never returned

Failure mode: you correctly inject clickid into the offer URL, but the network's postback template does not echo it back. Conversions arrive with no key, your tracker cannot attribute them, and they pile up as "unmatched."

Fix — 5 steps:
— Confirm the network captures your clickid on the click — send it in the slot they read (often sub1 or aff_sub), not a slot they ignore.
— Confirm their postback template returns that same value to your tracker's {clickid} token.
— Both halves must use the same identifier. Passing it on the way in but not on the way out breaks matching silently.
— Check the tracker's "unmatched conversions" report regularly — a rising count is your early-warning signal.
— Document the exact parameter names on both legs so a future offer swap does not reintroduce the bug.

Verify: fire a test conversion and confirm it lands matched to the correct click, not in the unmatched bucket.
