1
Ask for the connector ~ minutes
Plain language, no code.
Tell Polar's AI Data Engineer what you want from Nextdoor Ads 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 Nextdoor Ads API exposes a field, you can have it, down to a single hidden one the standard connector never pulled.
2
Spend and conversions blended automatic
Deduplicated.
Polar matches Nextdoor Ads spend and conversions to your Shopify orders and re-attributes them on its own model, so blended ROAS, MER and CAC are computed after platform overclaiming is removed.
3
Judged on margin the payoff
Not just on return.
Every attributed order carries its cost of goods and contribution margin, so a channel that looks efficient on revenue and thin on profit is visible in the same table.
Side by side
Nextdoor Ads reports Nextdoor Ads. Your budget lives across every channel.
Nextdoor Ads grades its own homework: the numbers count the conversions it can claim, before deduplication, and it cannot see what the other platforms, email or your store contributed. Polar reads Nextdoor Ads next to every other channel on one P&L.

The Gap
The connector is only half of it.
Once Nextdoor Ads 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.
