Core concepts
Privacy firewall
The privacy firewall limits what leaves the publisher app and keeps sensitive application context out of ad-facing paths.
Controlled egress
Send only the fields needed for sponsorship decisions. Use project configuration for defaults instead of repeating sensitive values in every request.
Browser boundaries
Publishable keys require allowed origins and browser activation. Secret keys remain server-only.
Logs and redaction
Request IDs are safe to share. API keys, activation tokens, and user identifiers should be redacted from application logs.
Need help with your integration?
Share the affected endpoint, request ID, and the behavior you expected. Leave out keys and user content.
