Data Synchronization Identifiers

Last updated on Jul 18, 2023

An Activation uses identifiers to synchronize data from the Activate Warehouse with objects in the Target CRM application. These are fields or properties that contain detailed metadata for the Target objects. They help identify the data records to be replicated. You can either use a unique identifier, a composite identifier, or a matching identifier.

  • Unique Identifier: A unique identifier is a property similar to a primary key in relational databases. It helps to uniquely identify records in the Target object with which data from the Warehouse is synchronized.

    For example, in the Salesforce Account object, the AccountId field is a unique identifier for each record in the object.

  • Matching Identifier: A matching identifier is a property that helps identify the data to be synchronized in the Target. It can be a unique or a non-unique property. If you select a unique property as a matching identifier, then its behavior is similar to that of a unique identifier. If you select a non-unique property as a matching identifier, all records in the Target object that match the property‚Äôs value are updated.

    For example, in the HubSpot Contacts object, the City field can hold multiple values, such as San Francisco or Los Angeles. Now, if you select City as a matching identifier, then all the records in the Target object that match any of these values are updated. Therefore, City is a non-unique property.

Note: You cannot change the selected data synchronization identifier once you create the Activation.


  • You cannot change the identifier once you create the Activation.
