# Better Auth

> Learn how to track lead conversion events with Better Auth and Dub

> [!TIP]

> This feature is only available on [Business plans and
> above](https://dub.co/pricing).

When it comes to [conversion tracking](/docs/concepts/attribution), a `lead` event happens when a user performs an action that indicates interest in your product or service. This could be anything from:

* Signing up for an account
* Booking a demo meeting
* Joining a mailing list

![A diagram showing how lead events are tracked in the conversion funnel](https://assets.dub.co/help/conversion-lead-event.png)

In this guide, we will be focusing on tracking new user sign-ups for a SaaS application that uses Better Auth for user authentication.

## Prerequisites

First, you'll need to enable conversion tracking for your Dub links to be able to start tracking conversions:

> [!TIP]
>
> If you're using [Dub Partners](https://dub.co/partners), you can skip this
> step since partner links will have conversion tracking enabled by default.

> **Option 1: On a workspace-level**
>
> To enable conversion tracking for all future links in a workspace, you can do the following:
> To enable conversion tracking for all future links in a workspace, you can do the following:
>
> 1. Navigate to your [workspace's Tracking settings page](https://app.dub.co/settings/tracking).
> 2. Toggle the **Workspace-level Conversion Tracking** switch to enable conversion tracking for the workspace.
>

>
> This option will enable conversion tracking in the [Dub Link Builder](/help/article/dub-link-builder) for all future links.

> **Option 2: On a link-level**
>
> If you don't want to enable conversion tracking for all your links in a workspace, you can also opt to enable it on a link-level.
>
> To enable conversion tracking for a specific link, open the [Dub Link Builder](/help/article/dub-link-builder) for a link and toggle the **Conversion Tracking** switch.
>

>
> > [!TIP]
> >
> > You can also use the `C` keyboard shortcut when inside the link builder to
> > quickly enable conversion tracking for a given link.

> **Option 3: Via the API**
>
> Alternatively, you can also enable conversion tracking programmatically via the [Dub API](/docs/api-reference/introduction). All you need to do is pass `trackConversion: true` when creating or updating a link:
>
> ```javascript Node.js theme={null}
> const link = await dub.links.create({
>   url: "https://dub.co",
>   trackConversion: true,
> });
> ```
>
> ```python Python theme={null}
> link = d.links.create(url="https://dub.co", track_conversion=True)
> ```
>
> ```go Go theme={null}
> link, err := d.Links.Create(ctx, &dub.CreateLinkRequest{
>     URL: "https://dub.co",
>     TrackConversion: true,
> })
> ```
>
> ```ruby Ruby theme={null}
> s.links.create_many(
>   ::OpenApiSDK::Operations::CreateLinkRequest.new(
>     url: "https://dub.co",
>     track_conversion: true,
>   )
> )
> ```

Then, you'd want to install the Dub Analytics script to your website to track conversion events.

You can install the Dub Analytics script in several different ways:

> **[React](/docs/sdks/client-side/installation-guides/react)**

> **[Manual installation](/docs/sdks/client-side/installation-guides/manual)**

> **[Framer](/docs/sdks/client-side/installation-guides/framer)**

> **[Shopify](/docs/sdks/client-side/installation-guides/shopify)**

> **[WordPress](/docs/sdks/client-side/installation-guides/wordpress)**

> **[Webflow](/docs/sdks/client-side/installation-guides/webflow)**

> **[Google Tag Manager](/docs/sdks/client-side/installation-guides/google-tag-manager)**

> [!TIP]
>
> You can **verify the installation** with the following tests:
>
> 1. Open the browser console and type in `_dubAnalytics` – if the script is installed correctly, you should see the `_dubAnalytics` object in the console.
> 2. Add the `?dub_id=test` query parameter to your website URL and make sure that the `dub_id` cookie is being set in your browser.
>
> If both of these checks pass, the script is installed correctly. Otherwise, please make sure:
>
> * The analytics script was added to the `<head>` section of the page
> * If you're using a content delivery network (CDN), make sure to purge any cached content

## Installation

**1. Install the @dub/better-auth plugin**

To get started, simply install the [`@dub/better-auth` plugin](https://www.npmjs.com/package/@dub/better-auth) via your preferred package manager:

```bash npm theme={null}
npm install @dub/better-auth
```

```bash yarn theme={null}
yarn add @dub/better-auth
```

```bash pnpm theme={null}
pnpm add @dub/better-auth
```

```bash bun theme={null}
bun add @dub/better-auth
```

**2. Configure the plugin**

Then, add the plugin to your better-auth config file:

```ts auth.ts theme={null}
import { dubAnalytics } from "@dub/better-auth";
import { betterAuth } from "better-auth";
import { Dub } from "dub";

const dub = new Dub();

export const auth = betterAuth({
  plugins: [
    dubAnalytics({
      dubClient: dub,
    }),
  ],
});
```

## View your conversions

Once you've completed the setup, all your tracked conversions will show up in [Dub Analytics](https://dub.co/analytics). We provide 3 different views to help you understand your conversions:

* **Time-series**: A [time-series view](https://app.dub.co/dub/analytics?view=timeseries) of the number clicks, leads and sales.

![Time-series line chart](https://mintcdn.com/dub/F9cdc9nB_SI4yl65/images/conversions/timeseries-chart.png?fit=max\&auto=format\&n=F9cdc9nB_SI4yl65\&q=85\&s=7380bc6120ade538b2b65eefdc76d3ed)

* **Funnel chart**: A [funnel chart view](http://app.dub.co/analytics?view=funnel) visualizing the conversion & dropoff rates across the different steps in the conversion funnel (clicks → leads → sales).

![Funnel chart view showing the conversion & dropoff rates from clicks → leads → sales](https://mintcdn.com/dub/F9cdc9nB_SI4yl65/images/conversions/funnel-chart.png?fit=max\&auto=format\&n=F9cdc9nB_SI4yl65\&q=85\&s=6275caafcfc3be6d8b498149222f225e)

* **Real-time events stream**: A [real-time events stream](https://app.dub.co/events) of every single conversion event that occurs across all your links in your workspace.
