Nextdoor Ads
Conversion tracking for Nextdoor advertising campaigns.
Datafly Signal delivers first-party events to Nextdoor Ads server-to-server from infrastructure you control, using a pre-built blueprint that maps your event schema to the payload Nextdoor Ads expects.
Why route Nextdoor Ads through Datafly Signal
Conversions survive ad blockers and tracking prevention
A browser tag served from an advertising domain is blocked outright for part of your traffic, and Safari's ITP shortens the cookies it can set. Signal sends the event from your own server, so the conversions Nextdoor Ads optimises against are not filtered by the browser.
Email and phone number hashed before it leaves your infrastructure
Signal normalises (trim and lowercase) and applies SHA-256 inside your own deployment, so Nextdoor Ads receives match keys rather than raw personal data.
Client IP and user agent are preserved
Server-to-server delivery normally loses both, which weakens matching. Signal forwards the genuine visitor values as request headers so Nextdoor Ads attributes the event to the right session.
One consent decision governs every destination
Nextdoor Ads is gated by the same consent state as the rest of your stack, so a withdrawal applies everywhere at once.
What ships in the blueprint
Mapped events

Retail, Lead Generation. Each preset starts from a working configuration for that vertical rather than a blank field map.
Full field mappings, configuration fields, and troubleshooting are in the Nextdoor Ads documentation.
Frequently asked questions
Does Datafly Signal integrate with Nextdoor Ads?
Yes. Datafly Signal delivers first-party events to Nextdoor Ads server-to-server from infrastructure you control, using a pre-built blueprint that maps your event schema to the payload Nextdoor Ads expects. The integration is included in every deployment at no additional cost.
How is server-side Nextdoor Ads tracking different from the Nextdoor Ads tag?
The Nextdoor Ads tag runs in the visitor's browser, so it is subject to ad blockers, tracking prevention, and page-unload races. Signal collects the event through a first-party endpoint on your own domain and delivers it to Nextdoor Ads from your server, so delivery does not depend on browser conditions.
What personal data is sent to Nextdoor Ads?
Email and phone number are normalised and SHA-256 hashed inside your own deployment before delivery, so Nextdoor Ads receives match keys rather than raw personal data. Which fields are sent is configured per pipeline.
Which events can Signal send to Nextdoor Ads?
The blueprint ships with mappings for add_to_cart, generate_lead, page, purchase, sign_up, view_item. Any event in your schema can be mapped to Nextdoor Ads through pipeline configuration without a code change.
Do I need to keep the Nextdoor Ads tag on my site?
No. Server-side delivery is designed to replace the tag. Most teams run both briefly during migration, using shared event IDs so Nextdoor Ads deduplicates, then remove the tag once server-side volume matches.
