Stamped in Polar: reviews read against conversion and repeat rate.
Stamped collects the ratings. What it cannot show is whether they sell, because conversion, repeat purchase and margin all live outside the review widget. Bring ratings, volume and sentiment into Polar and social proof stops being a vanity number and starts explaining revenue.

Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Stamped 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 Stamped API exposes a field, you can have it, down to a single hidden one the standard connector never pulled.

Reviews on the product automatic
Rating, meet revenue.
Polar joins Stamped ratings and review volume to the products they belong to, so social proof is read against conversion, revenue and return rate at SKU level.

Read it against margin the payoff
Proof, priced.
Rating and volume sit next to contribution margin and repeat rate, so review collection effort goes to the products where it moves the number.
Side by side
Stamped counts the stars. Polar tells you what they earned.
Ratings and volume live in the review widget, away from conversion, returns and margin, so social proof is reported as a score. Polar joins them to the product and the order, and the score becomes a signal.
