Yahoo! Japan CAPI Payload Preview

The server-side request adscapi builds when you track() a purchase and Yahoo! Japan is configured. Secrets and hashed values show as placeholders.

Verified against the library dispatcher (src/dispatchers/yahoojp.ts). See the Yahoo! Japan setup guide for where to get each secret.

Required secrets

YAHOOJP_PIXEL_IDYAHOOJP_TOKEN

Yahoo! Japan activates when every secret is present. One missing key and the platform no-ops — the rest still receive the event.

Good to know

  • Token goes in the X-TagAccessToken header; the tag id rides in the body as tag_id.
  • hashed_email and hashed_phone_number send only with adUserData consent; no IP is sent.
  • event_time is unix seconds; unmapped canonical names pass through raw and Yahoo answers 400 — send only mapped events.
