## Tag Configuration in Tealium iQ

### Adding the Tag

Tealium iQ's Tag marketplace offers a wide variety of tags. Click [here](https://docs.tealium.com/manage-tags/) to learn how to add a tag to your profile.

### Configuring the Tag

1. **Title**: (Required) Enter a descriptive title to identify the tag instance.
1. **Account ID**: (Optional) Enter the numeric merchant ID provided to you by Nextag. You also have the option to dynamically set this field by mapping to `id` as the destination variable (see [Setting up Mappings](#mappings)). For example, `12345`.

### Applying Load Rules

[Load Rules](https://docs.tealium.com/about-load-rules/) determine when and where to load an instance of this tag. The **Load on All Pages** rule is the default load rule. To load this tag on a specific page, create a new load rule with the relevant conditions.

**Best Practice**: Set up load rule conditions to load this tag on the order confirmation page (Thank You or Receipt) of your site.

### Setting up Mappings

[Mapping](https://docs.tealium.com/about-data-mappings/) is the simple process of sending data from a data source, in your Data Layer, to the matching destination variable of the vendor tag. The Mapping toolbox for this tag does not offer any pre-defined destination variables. However, you can dynamically set the Account ID with a mapping. To do so, select the appropriate data source from the drop-down list and enter `id` in the adjacent text field (see example screenshot below).


<blockquote>
Make certain that the [E-Commerce Extension](https://docs.tealium.com/e-commerce-extension/) is set up and configured before you configure this tag. The E-Commerce variables this tag uses are `_cprod`, `_corder`, `_ccat`, `_cquan`, and `_ctotal`.
