# Reddit Pixel

The c15t redditPixel helper loads the Reddit Pixel only after visitors allow marketing in Inth. On withdrawal, it turns off first party cookies and c15t reloads.

## Key facts

- **Tool:** Reddit Pixel
- **Category:** Advertising
- **Consent categories:** Marketing
- **Setup method:** c15t package
- **Package:** @c15t/integrations

Keep the Reddit Pixel off the page until visitors allow marketing. On withdrawal, c15t turns off its first party cookies and reloads the page.

Inth keeps the consent record of each choice, with the visitor’s country and the policy that applied.

## Before you start

You need an Inth project that connects to your app, c15t in that app and your Reddit Pixel ID.

New to c15t? Complete the quickstart for your framework first. Keep its Inth endpoint, policy, styles and consent UI.

## How consent works with the Reddit Pixel

Before marketing has permission, the c15t redditPixel helper defines no rdt function and loads nothing from Reddit.

After permission, the helper queues init and PageVisit. Then it loads pixel.js. It sends no consent signal to Reddit.

On withdrawal, the helper calls rdt('disableFirstPartyCookies'). That call does not stop events. So the reload and your own permission check stop them.

If the visitor allows marketing again before the reload, the helper calls rdt('enableFirstPartyCookies').

## Installation

The Reddit Pixel has one load mode in c15t. The helper waits for marketing permission.

### Wait for permission

No request goes to Reddit until the visitor accepts marketing. On withdrawal, c15t reloads the page.

```ts
redditPixel({ pixelId })
```

An opt-out policy or no policy gives optional categories permission before a choice. Then the Reddit Pixel loads on the first page. This guide uses an opt-in policy.

## Setup steps

#### Install the integration package

Add the helpers next to c15t. An import alone does not start the Reddit Pixel.

```
pnpm add @c15t/integrations
```

#### Add your pixel ID

The helper passes the pixel ID to rdt('init'). It also sends the page visit.

```
import { redditPixel } from '@c15t/integrations/reddit-pixel';

export const scripts = [redditPixel({ pixelId: 't2_YOUR_PIXEL_ID' })];
```

The package also exports redditPixelEvent. It does not check permission, so check it before each call.

#### Check permission before each conversion

window.rdt still exists after withdrawal. Set conversionId to match the Conversions API event.

```
export function trackPurchase(marketingAllowed: boolean, orderId: string) {
  if (!marketingAllowed || typeof window.rdt !== 'function') return;
  window.rdt('track', 'Purchase', {
    conversionId: orderId,
    currency: 'USD',
    value: 99.99,
  });
}
```

### Register it with your existing setup

#### Next.js

Add scripts to c15t.config.ts, next to next.config.ts. Keep the rest of your config, such as mode, in the same call. App Router, Pages Router and static export read the same file.

```
import { defineConsentConfig } from 'c15t/next';
import { scripts } from './src/consent-scripts';

export default defineConsentConfig({ scripts });
```

#### TanStack Start

Pass scripts to the ConsentRoot in your root route. Import helpers in the route module, not in a server function: script configurations carry callbacks.

```
import { scripts } from '../consent-scripts';

<ConsentRoot state={consent} scripts={scripts}>
```

#### React

Add scripts to the options of your ConsentProvider, next to mode. Keep the banner, dialog and preferences link inside the provider.

```
import { scripts } from './consent-scripts';

<ConsentProvider options={{ mode, scripts }}>
```

#### Nuxt

Register scripts under the c15t key in app.config.ts. Keep them out of nuxt.config.ts, which reaches the browser as JSON and drops the helper callbacks.

```
import { scripts } from '../src/consent-scripts';

export default defineAppConfig({
  c15t: { scripts },
});
```

#### Vue

Pass scripts to the c15tVue plugin call you have now. The plugin starts one script loader when the app mounts.

```
import { c15tVue, manifest } from 'c15t/vue/vue-plugin';
import { scripts } from './consent-scripts';

app.use(c15tVue, {
  mode: manifest(),
  scripts,
});
```

#### Astro

Add scripts to the client entrypoint, which the integration finds on its own. Keep helpers out of astro.config.mjs: its options are serialized into the page.

```
import type { C15tClientOptionsExtension } from 'c15t/astro';
import { scripts } from './consent-scripts';

export default { scripts } satisfies C15tClientOptionsExtension;
```

#### Svelte

Pass scripts as a prop to the ConsentProvider you have now. The provider owns the loader and disposes it on unmount.

```
<script lang="ts">
  import { ConsentProvider, manifest } from 'c15t/svelte';
  import { scripts } from './consent-scripts';
</script>

<ConsentProvider mode={manifest()} {scripts}>
  <!-- Your app and consent UI -->
</ConsentProvider>
```

#### SvelteKit

Add scripts to the ConsentRoot in the root layout. Import helpers in the layout component, not in +layout.server.ts: a server load cannot send functions to the browser.

```
<script lang="ts">
  import { ConsentRoot } from 'c15t/svelte';
  import { scripts } from '../consent-scripts';

  let { children, data } = $props();
</script>

<ConsentRoot state={data.consent} {scripts}>
  {@render children()}
</ConsentRoot>
```

#### HTML: Paste the vendor’s snippet behind consent

The helpers need a bundler. On a page with the c15t script tag, paste the vendor’s own snippet instead and keep it inert until visitors allow its category. Helper options, such as loadMode, do not apply.

```
<script type="text/plain" data-c15t-category="marketing">
  // The vendor's snippet, unchanged
</script>
```

#### JavaScript

Pass scripts to init() from @c15t/browser, next to your mode. With createConsentRuntime, pass scripts to it instead.

```
import { init, manifest } from '@c15t/browser';
import { scripts } from './consent-scripts';

const consent = init({
  mode: manifest(),
  scripts,
});
```

Remove the original Reddit Pixel snippet, so it cannot load the pixel without consent.

## Verify your setup

Use a private window with an opt-in policy. Open DevTools Network and filter by reddit. Then test the three states.

- **Before a choice**: pixel.js does not load, and window.rdt does not exist.

- **After you allow marketing**: pixel.js loads from www.redditstatic.com, and the pixel sends one PageVisit. A guarded event sends its own request.

- **After you withdraw marketing**: Until the reload, trackPurchase sends nothing.

Pass the current marketing permission from your framework, for example useConsent('marketing') in React.
