Cookie Synchronization

Cookie synchronization offers a way to associate 3rd-Party Cookie IDs to a User's Profile. These IDs can later be used by some Destinations.

CookieSync Providers#

CookieSync Providers represent 3rd-Party ID data sources which will be integrated with the Velocidi CDP via cookie synchronization. After a provider is created, the cookie synchronization integration can be started, and these IDs can be used to activate users to some Destinations.

Dashboard CookieSync Providers

The following fields are available:

  • Name: Name for the CookieSync Provider.

  • Key: Identifier for the CookieSync Provider. It is used later to perform cookieSync for this specific provider.

  • Active: Enables/disables integrations with this CookieSync Provider.

  • URL for cookie synchronization: If no 3rd-party ID (uid field) is received in the cookieSync request, the request will be redirected to this URL to synchronize our ID with the 3rd-Party provider. This field supports templating using the liquid template language, and the user ID can be interpolated using the {{ meta.USER_ID }}. This field can be left empty if you only plan to perform cookie synchronization while knowing the 3rd-Party ID.

    Example: http://thecookiesync.com/sync?id={{ meta.USER_ID }}.

Cookie Synchronization#

The cookie synchronization process has 2 variants:

  • The CookieSync Provider provides a 3rd-Party Cookie ID:

    With this approach, every cookie synchronization request will send the 3rd-Party ID which will be stored in Velocidi CDP directly. Any activation using this CookieSync Provider User ID will use this ID.

  • The CookieSync Provider doesn't provide a 3rd-Party Cookie ID:

    In this approach, requests will be sent without the unknown 3rd-Party Cookie ID. To create the mapping between the 2 systems, the request will be redirected to the 3rd-Party with a unique ID generated by the Velocidi CDP for that user. Any activation using this CookieSync Provider User ID will use this ID.

    note

    With this approach, the URL for cookie synchronization must be defined in the CookieSync Provider configuration.

To perform cookie synchronization we provide 2 approaches:
