# Implementing the Roadway Tag

Follow the steps below (15-45 mins) to enable marketing attribution on metrics derived from CRM data through Anonymous IDs from Sessions on CRM contacts.

## Overview

Add Attribution IDs to CRM contacts via Roadway tag.

### 2. [Choose your Form provider & complete mapping](#id-2.-choose-your-form-provider-and-complete-id-mapping)

## **1. Add Roadway Attribution Tag**

Growth marketing teams need to attribute customers across all key growth metrics in order to effectively spend time and budgets. The lack of tools and integrations to pass the right IDs across data platforms to attribute every customer touchpoint across those metrics is the main reason why companies rarely do this. The **Roadway Attribution Tag** bridges the gap—starting with passing anonymousIDs to CRMs to enable end-to-end marketing attribution on sales funnel metrics. It works like this:

* **Before the form** – captures the anonymous ID your analytics tool (GA4 or Segment) assigns to each browser.
* **During the form** – writes that ID into hidden form fields automatically.
* **After the form** – when the submission becomes a CRM contact and lands in your data warehouse, you can join the visitor’s pre-signup behavior to the new customer record.

**Result:** full-funnel reporting that shows *which channels and campaigns actually turn visitors into revenue.*

#### Setup

Add the following script tag to the `<head>` section of your website or on Google Tag Manager to All Pages:

```
<script defer src="//analytics.roadwayai.com/tag.js"></script>
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.roadwayai.com/required-ids-for-attribution/implementing-the-roadway-tag.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
