## Tag tips

* Supports the following [E-Commerce extension](https://docs.tealium.com/e-commerce-extension/) parameters:
    * Offer ID (`_cprod`)
    * Conversion ID (`_corder`)
    * Conversion Value (`_ctotal`)
    * Category ID (`_ccat`)
* UID should be an anonymized user ID (for example, based on the user email or login). If none is provided, the tag will send the value `unknown`.

## Tag configuration

Go to the tag marketplace to add a new tag. For more information about how to add a tag, see [Manage tags](https://docs.tealium.com/manage-tags/).

When adding the tag, configure the following settings:

* **Tagging Hash**: Your RTB House Tagging Hash.
* **Region Subdomain**: Your RTB House Region Subdomain.

## Load rules

Load the tag on all pages or set conditions for when your tag will load. For more information, see [About load rules](https://docs.tealium.com/about-load-rules/).

## Data mappings

Mapping is the process of sending data from a data layer variable to the corresponding destination variable of the vendor tag. For more information, see [About data mappings](https://docs.tealium.com/about-data-mappings/).
