[AdCP Signals] Activate an audience signal for DSP targeting.
Returns an activation_key token for referencing this signal activation. Free-form
Trillboards signal labels remain custom parameters. IAB Audience Taxonomy 1.1
segments are emitted only when registered IDs are supplied explicitly.
WHEN TO USE:
- Converting audience signals into actionable targeting parameters
- Activating already-curated, registered IAB segment IDs for programmatic requests
- Creating reusable targeting configurations
RETURNS:
- activation_key: Token for referencing this activation (24h expiry)
- targeting: { iab_segments, iab_taxonomy_version, custom_params }
- screen_count, provider, data_source, methodology
EXAMPLE:
User: "Activate the registered $100k-$149k household-income segment on my screens"
activate_signal({
signal_type: "audience",
parameters: { iab_audience_segment_ids: ["68"] },
screen_ids: ["507f1f77bcf86cd799439011"]
})
