Yahoo Japan Ads
Server-side conversion measurement for Yahoo! JAPAN Ads (LINEヤフー) Display Ads via the Conversion API (POST https://ads-cv.yahooapis.jp/v1/). Sends conversions with yclid click matching plus SHA-256 hashed email/phone, forwarded IP/User-Agent, and transaction-ID deduplication. Conversion-only API — page views and funnel mid-steps are dropped.
Datafly Signal delivers first-party events to Yahoo Japan Ads server-to-server from infrastructure you control, using a pre-built blueprint that maps your event schema to the payload Yahoo Japan Ads expects.
Why route Yahoo Japan 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 Yahoo Japan 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 Yahoo Japan Ads receives match keys rather than raw personal data.
Client IP and user agent are carried in the payload
Both are taken from the original visitor request rather than your server, which is what Yahoo Japan Ads needs to attribute the event to the right session.
One consent decision governs every destination
Yahoo Japan 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
generate_leadpurchasesign_upVertical presets
Default. 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 Yahoo Japan Ads documentation.
Frequently asked questions
Does Datafly Signal integrate with Yahoo Japan Ads?
Yes. Datafly Signal delivers first-party events to Yahoo Japan Ads server-to-server from infrastructure you control, using a pre-built blueprint that maps your event schema to the payload Yahoo Japan Ads expects. The integration is included in every deployment at no additional cost.
How is server-side Yahoo Japan Ads tracking different from the Yahoo Japan Ads tag?
The Yahoo Japan 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 Yahoo Japan Ads from your server, so delivery does not depend on browser conditions.
What personal data is sent to Yahoo Japan Ads?
Email and phone number are normalised and SHA-256 hashed inside your own deployment before delivery, so Yahoo Japan Ads receives match keys rather than raw personal data. Which fields are sent is configured per pipeline.
Which events can Signal send to Yahoo Japan Ads?
The blueprint ships with mappings for generate_lead, purchase, sign_up. Any event in your schema can be mapped to Yahoo Japan Ads through pipeline configuration without a code change.
Do I need to keep the Yahoo Japan 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 Yahoo Japan Ads deduplicates, then remove the tag once server-side volume matches.
