TUNE parameter
What is the offer_id parameter?
offer_id is TUNE's tune offer identifier. offer_id names the specific campaign in TUNE (HasOffers) white-label programs — VPNs, fintechs, and direct brands run these on their own tracking domains. When a brand hands you a "new link", it usually means a new offer_id, and the old one’s days are numbered.
Where it appears
In the affiliate link you publish
Example
https://track.brand-offers.com/aff_c?offer_id=15&aff_id=43185If offer_id is missing
An offer_id pointing at a retired offer is the #1 TUNE failure: the link errors or redirects to a default page with no payout mapping. Brands version offers and retire old IDs on their own schedule.
How TUNE tracking fits together
TUNE is white-label software: each brand runs it on its own tracking domain (track.brand.com, go.brand-offers.com, etc.). Links hit an /aff_c or /aff_l endpoint with offer_id and aff_id, register the click, and redirect to the offer’s landing page.
Because every brand’s domain is different, TUNE links are identified by their parameter signature, not their domain — which is exactly how Afterlink’s detector recognizes them. Offers are versioned and retired frequently; offer_id=15 might be replaced by offer_id=42 with a new landing page, orphaning your old links.
