Signifyd in Polar: what fraud and false declines really cost.
Signifyd approves or declines the order. What it cannot tell you is what the decision cost, because a chargeback shows up in your ledger and a false decline never shows up at all. Bring decisions, chargebacks and reviews into Polar and both sides of the trade-off land in your margin.

Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Signifyd in plain language. It reads the source documentation, lays out everything the API offers by category, then writes the connector and pipes the data into your warehouse as governed data. No code, and it ships in minutes.
Worth knowing: this also works on connectors you already have. If the Signifyd API exposes a field, you can have it, down to a single hidden one the standard connector never pulled.

Decisions on the order automatic
Approve, decline, chargeback.
Polar matches Signifyd decisions to your Shopify orders, so approvals, declines and chargebacks are attached to the revenue and the margin each one represents rather than to a monthly rate.
3
Both costs, visible the payoff
Loss and lost revenue.
Fraud loss and the revenue declines turned away sit on the same statement, so tightening the rules is a decision with two numbers instead of one.
Side by side
Signifyd makes the call. Polar tells you what it cost.
A chargeback is visible and a false decline is not, so rules get tightened past the point where they pay. Signifyd reports the decisions; Polar prices both sides of them against the revenue and the margin each one moved.

Chargeback loss is a monthly rate, not an order.
Loss matched to the orders it reversed, by product and market.
The revenue a decline turned away is invisible.
Declined orders priced as the revenue and margin they would have been.
Fraud sits outside the margin calculation.
Loss and review cost inside contribution margin.
A blanket rule for a problem that is not spread evenly.
Rates by product and destination, so rules can be targeted.
The Gap
The connector is only half of it.
Once Signifyd is modelled 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.
