Webgains Tag Setup Guide

This article describes how to set up the Webgains tag.

Tag tips

Use the E-Commerce extension to set values for _corder, _csubtotal, _ccustid, _cpromo.
Map an array value to wgvouchercode to set product-level vouchers.
Requires that _cprice has a list of prices.
wgitems is set automatically using E-Commerce Extension values (_cprice, _cprodname, _cprod). To override these E-Commerce Extension values, map a string to this variable.
Map a discount value to wgDISCOUNT to set an order-level discount. The tag converts this value to a negative amount and adds a discount line item to the product list.
The tag fires a landing page script on every page and a conversion script on order confirmation pages. The conversion script sends a cvr object built from your data layer variables and an items[] array built automatically from _cprice, _cprodname, _cprod, and _cquan. Only one conversion fires per unique order reference per page load.

Tag configuration

Go to the tag marketplace to add a new tag. For more information about how to add a tag, see Manage tags.

When adding the tag, configure the following settings:

Program ID: Your Webgains Program ID. The tag uses this value to construct the analytics endpoint URL: https://analytics.webgains.io/{programid}/main.min.js. See the Webgains Default Tracking Guide for details.
Event ID: Required value. Webgains uses Event ID to determine commission rate. See the Webgains Default Tracking Guide for your Event/Commission Group ID.
Enable Legacy Transaction Pixel: When enabled, the tag fires both the new analytics.webgains.io conversion tracking and the legacy track.webgains.com/transaction.html pixel. Disable this option after you complete migration to Default Tracking.

Load rules

Load the tag on all pages or set conditions for when the tag will load. For more information, see 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.
