From your dashboard, open Get help and describe what you need. The request goes into the partner support queue with your account already attached.
That attachment is the point. A question emailed from an address the team cannot tie to a partner account is the one request they cannot safely answer — anything about your ledger, your payouts or your bank details needs to be provably you. Sending it from inside your signed-in session proves it.
Expect a reply within 24–48 hours, to your account email address.
If you cannot sign in at all, that is a different path: use /partners/recover, which routes into the same queue with identity evidence attached.
Include specifics — an employer name, a date, an amount, what you expected to see. Vague reports take a round trip to clarify.
The partner help centre covers attribution, the ledger, payouts and the selling rules.
