Cookiebot and Complianz, both WordPress privacy plugins have initiated the Consent API, which is most likely released as a feature plugin for WordPress 5.6.
The API will create a layer between plugins, and consent management plugin to standardize consent. Plugin developers can conform to the API so their users can be compliant with international privacy laws.
As the owner/developer I would like to ask Hubspot to conform with this API. I will create an integration that helps Hubspot users on WordPress to process data requests, consent boxes on forms, and load Hubspot cookies based on privacy law and user choices.
More information can be found here: wpconsentapi.org - on this page you will find the API as well, including documentation on Github. For help, more information etc, please let me know.
If you could redirect me to a dev team for WordPress I'm happy to help. We have seen many clients, both on Complianz and HubSpot that are in need of a standardized solution.
