Awin commission validation for Shopify
Validate Awin commissions against Shopify refunds before auto-validation: the 67-day Access limit, the batch CSV, the API and what the Shopify app covers.
By The AffCheck team · Updated
Checked 18 Sept 2026 · from Awin’s own documentation
On Awin, every tracked sale sits as pending until you approve, decline or amend it. When the auto-validation period runs out, whatever you have not reviewed is approved and invoiced, plus Awin’s fee on the sale. For a Shopify brand with a real returns rate, that period is the whole game: decline refunded orders inside it, or pay for them.
Awin is also the network with the clearest tooling for doing this in bulk: a batch upload on Awin Classic, a validation API on the bigger plans, and a Shopify app that declines some cancellations for you. Each of those has limits worth knowing before you rely on it.
What Awin calls it
| Not paying a commission | Decline |
|---|---|
| Paying less (partial refund) | Amend (you change the sale amount; the commission is recalculated) |
| The deadline | Auto-validation period (AVP) |
The deadline: auto-validation period (avp)
Set per programme to mirror your returns window, and it can’t be switched off. On Awin Access the longest period is 67 days; on Accelerate and Advanced it depends on sector and contract.1
Exporting pending transactions
Awin Classic: Reports → Performance → Transactions, filtered to pending, exported as CSV. New Awin: Commissions → Review commission payments → Review pending → Export.2
Uploading declines
Awin Classic: Commission → Validate → Batch Process Commission → Manual Upload, using the Accepted, Declined and Amended templates Awin provides on that page. On new Awin you approve or decline in the list; batch upload is Classic only.3
Format: Awin batch validation CSV (Order Reference, Transaction Date, Status, Status Note; amends add Sale Amount, Sale Breakdown and Currency)
API access
A transaction validation API (approve, decline, amend; up to 40,000 per request). Advertiser APIs come by default on Accelerate and Advanced.4
The Awin Shopify app
Awin ‑ Affiliate Marketing (1.9★ from 33 reviews on 18 Sep 2026). Tracking and product feed, plus Shopify auto-validation: on Awin Classic, after Awin whitelists your domain, cancelled orders placed after activation are declined and partial refunds adjusted. The app’s returns period is its own setting, not your Awin validation period.5

How AffCheck handles Awin
AffCheck reads the pending-transactions export (or, later, the API) and matches every row to its Shopify order. Full refunds and cancellations become declines, partial refunds become amends with the new sale amount worked out, and orders it can’t find are flagged to check.
If you already use Shopify auto-validation, AffCheck is the second pair of eyes: it shows the refunded orders the app did not touch, such as orders from before activation, refunds that landed after the app’s own returns period, or programmes on the new platform.
What no Awin tool sees is your other networks. If the same order was also claimed on CJ, or a creator’s code was used by a voucher site, AffCheck flags that too, with the reason Awin lists as a legitimate decline.

FAQ
Questions, answered
Can I decline an Awin transaction after it was auto-approved?
Not yourself. Awin says approved commissions can’t be reversed; its support team may help in exceptional cases. That is why the deadline matters.
Should I decline or amend a partial refund on Awin?
Amend it: you change the sale amount to what the customer kept and Awin recalculates the commission. A full refund is a decline, not an amend to zero.
Does the batch upload work on the new Awin platform?
Awin documents the batch upload for Awin Classic. On the new platform you approve or decline in the pending list, or use the API if your plan includes it.
Does AffCheck need my Awin login?
No. It reads the CSV you export. An API connection is optional and only where your Awin plan includes the validation API.
