Set visitor opt-out flag in analytics from webhooks

Opt-out webhooks arrive without a visitor flag, so teams keep processing excluded users. The workflow sets visitor opt-out metadata, stopping processing for those users within minutes.

Overview

Unapplied opt-out signals let analytics and feature gates keep acting on excluded users, creating compliance risk and bad customer experiences. This flow ensures opt-outs set the visitor metadata directly, stopping processing and aligning analytics within minutes so product and privacy teams stay audit-ready.
