When adding the tag, configure the following settings:

* **Identifier**

  * The language of the page.
  * Example: NL.
  * You can dynamically override this value with a mapping.

## Data mappings

Mapping is the process of sending data from a [data layer variable](https://docs.tealium.com/data-layer-variables/) to the corresponding destination variable of the vendor tag. For instructions on how to map a variable to a tag destination, see [data mappings](https://docs.tealium.com/iq-tag-management/data-mappings/manage/).
