Targeting & custom labels

custom_label_0–4 are prompt slots — Signal Packs, HHI matrices, and activation kits are not on platform DCO.

Last updated August 23, 2026

Signal Packs (HHI / weather / geo matrices, Google Ads Editor kits, VAST-per-segment) were a legacy kernel DCO plan. They are not available on platform-api.

What you can do today:

Put segment hints in the feed as custom_label_0 … custom_label_4.
Reference them in the template: "{{title}} for {{custom_label_0}} shoppers".
Slice rowIds so each engage is one audience (still ≤24 variants).
Traffic the resulting files yourself in Meta / Google / TikTok — or, where ad connections are enabled for your workspace (rolling out), connect an ad account (POST /ad-connections) and push variants as PAUSED creatives with POST /campaigns/{id}/publish; publishing never activates spend. GET /campaigns/{id}/insights then returns per-variant insight windows, with winners flagged significant only at ≥5,000 impressions. See Delivery.

Compliance, socio-economic suppression, and activation-kit generation are not automated on this path. Targeting execution — audience setup, budgets, and activating any published ad — stays in your ad account.
