GDPR Query String Macros
In the edit Pixel dialog box, two optional GDPR query string macros are available:
- GDPR: GDPR
- GDPR Consent: GDPR_CONSENT
These GDPR macros are also supported as Creative macros where applicable. For the full list of supported Creative macros, see the documentation here: Supported Macros

Work with your web developer to ensure these placeholders are implemented with the appropriate values for your integration.
