Amazon Pay in Polar: the fees taken out, the net revenue put in.
Amazon Pay reports what it processed. It cannot see your cost of goods, your ad spend or the rest of your revenue, so the money it shows is gross and the margin behind it is missing. Bring transactions, fees, refunds and disputes into Polar and they land on the same P&L as everything else, net of what Amazon Pay kept.

1
Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Amazon Pay in plain language. It reads the API, writes the connector and pipes the data into your warehouse as governed data, in minutes.
Worth knowing: what lands depends on what your account exposes. Transactions, fees, refunds and disputes are the usual set; you choose which ones you want, or import everything the API exposes.
2
Fees netted, revenue matched automatic
Gross in, net out.
Polar matches Amazon Pay transactions to your Shopify orders and nets the processing fees, refunds and disputes out, so revenue is what you kept rather than what was charged.
3
Read it against margin the payoff
Payment cost, in the P&L.
Payment cost sits alongside cost of goods, shipping and ad spend in contribution margin and net profit, so the price of taking money is visible next to everything else you spend.
Side by side
Amazon Pay reports what it processed. Polar reports what you kept.
Amazon Pay shows gross settlement and its own fees, with no view of your cost of goods, your shipping or your ad spend. Polar matches the transactions to your orders and nets fees, refunds and disputes out, so payment cost lands inside margin.

The Gap
The connector is only half of it.
Once Amazon Pay's fees and refunds are netted against your real orders inside Polar, you can use the result wherever you already work. Ask Polar in plain language, pull it live through the Polar MCP, or schedule it into the report your team reads every morning.
