A rejection isn't always bad news: most are legitimate returns or duplicates. What matters is telling them apart and knowing when to dispute. In PartnersMy every rejection carries its recorded reason — that's your starting point.
The protocol
1
Open the commission's traceability in Earnings and read the reason and who recorded it.
2
«Customer refund» or «duplicate» → case closed, normal.
3
«Declined by the advertiser» with no context and a pattern (all your sales from one program) → dispute it.
To dispute, contact support quoting the commission ID: the recorded traceability is your evidence and the team can escalate directly with the advertiser. Affiliates who dispute with data recover commissions; those who dispute «just because», don't.
Pro tipWatch the monthly pattern: if a program rejects over 30% of your sales sustainedly, that program doesn't deserve your traffic. Data gives you the freedom to walk away.
