After you fund a Wise batch, each payout still has a life of its own: the affiliate has to claim it, and Wise has to complete the transfer. A Wise webhook pushes those changes to GrowSurf as they happen, so the Payouts page reflects reality rather than the last time something polled.
The webhook is optional. Without it, payout data still updates, just more slowly.

The webhook reports on transfers GrowSurf created, so the integration has to be connected on the affiliate program first.

In Wise, go to Settings > Connect and manage apps, scroll to Developer tools, and open Webhooks. Select Create a new webhook, name it GrowSurf, use the webhook URL from the Wise setup docs, and subscribe to Transfer update events.
The program’s Payouts page groups payouts by status — Upcoming, Queued, Issued, Failed, and Reversed. A funded payout sits in Wise waiting for the affiliate, and GrowSurf keeps it pending until Wise reports the transfer completed. That is the gap the webhook closes.


Wise emails the affiliate a secure claim link, then again when the payout is sent and when the money lands. If they already have a Wise account they can claim it to an eligible balance. An unclaimed payout is cancelled and refunded after 7 days.
A payout can stay under Queued with a status of Needs review. GrowSurf will not resend it until the earlier transfer is resolved, which is what stops a double payment. Use Check Wise status to re-examine the earlier transfer; when it is safe, the action changes to Retry via Wise and GrowSurf resends it.
It lives in your Wise account settings, so a single webhook covers the transfers GrowSurf creates from your Wise Business account.
Needs review exists so the same affiliate is not paid twice. Creating a replacement transfer in Wise defeats that check.
A payout that no one claims is cancelled and refunded. If an affiliate keeps missing it, confirm the email address on their Wise account is the one they actually read.
No, but it is worth the two minutes. Without it, payout statuses in GrowSurf can take some time to catch up with Wise.
Transfer update events. That is what reports a transfer moving from funded to claimed to completed.
No. The commission is marked paid only after Wise reports the transfer completed.
