## Configure the Pinterest Tag

Copy the numeric tag ID from Pinterest Ads Manager. Remove Pinterest's base
code and its `<noscript>` image. The helper does not emit that image, because
it fires without JavaScript and c15t cannot gate it.

|Package manager|Command|
|:--|:--|
|npm|`npm install @c15t/integrations@alpha`|
|pnpm|`pnpm add @c15t/integrations@alpha`|
|yarn|`yarn add @c15t/integrations@alpha`|
|bun|`bun add @c15t/integrations@alpha`|

```ts title="src/consent-scripts.ts"
import { pinterestTag } from '@c15t/integrations/pinterest-tag';

export const scripts = [pinterestTag({ tagId: '2613654212508' })];
```

## Register the scripts

Complete your [framework quickstart](/docs/frameworks) first. Keep its Inth
endpoint, policy, styles and consent UI. Remove the vendor's original script,
SDK initializer or tag-manager entry, so the vendor loads only through c15t.

The vendor pages put the helper in `src/consent-scripts.ts`. If your framework
quickstart already has a `scripts` array, such as the one in `c15t.config.ts`
in the Next.js guide, add the helper to that array instead of creating a
second file.
The `scripts` export is a configuration, not an initializer. Add it to the c15t provider you already have, at the registration
point for your framework below. These are edits to that provider, not a second
provider.

**Next.js**

Add the configuration to `scripts` in `c15t.config.ts`, next to
`next.config.ts`:

```ts title="c15t.config.ts"
import { defineConsentConfig } from 'c15t/next';
import { scripts } from './src/consent-scripts';

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

Keep the rest of your config, such as `mode` and `routePrefix`, in the
same call. `ConsentRoot` reads the config in the browser, so the layout
keeps passing only `state`. App Router, Pages Router and static export all
read the same file. See
[Next.js scripts and embeds](/docs/frameworks/next/scripts).

**TanStack Start**

Import the configuration into your root route and pass it to the existing
`ConsentRoot` as a top-level prop. Keep the loader from the
[TanStack Start quickstart](/docs/frameworks/tanstack-start/quickstart):

```tsx title="src/routes/__root.tsx"
import { scripts } from '../consent-scripts';

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

Import vendor helpers in the root route module, not in a server function.
A server function's return value must be serializable, and script
configurations carry callbacks. See
[TanStack Start scripts](/docs/frameworks/tanstack-start/scripts).

**React**

Add the configuration to the existing `ConsentProvider` options, next to
`mode`:

```tsx title="src/consent.tsx"
import { scripts } from './consent-scripts';

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

`mode` is the `manifest()` value from the
[React quickstart](/docs/frameworks/react/quickstart). Keep the banner,
dialog and preferences link inside the provider. See
[React scripts and embeds](/docs/frameworks/react/scripts).

**Nuxt**

Register the scripts under the `c15t` key in `app/app.config.ts`. Adjust the
relative import to where you created `consent-scripts.ts`:

```ts title="app/app.config.ts"
import { scripts } from '../src/consent-scripts';

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

The Nuxt module merges this over its options in `nuxt.config.ts` and starts
one script loader in the browser after hydration, once it has applied the
visitor's stored choice and privacy signals. Keep `scripts` out of
`nuxt.config.ts`, which reaches the browser as JSON and drops the vendor
callbacks. Write the vendor IDs into `consent-scripts.ts`. See
[Nuxt scripts and embeds](/docs/frameworks/nuxt/scripts).

**Vue**

Pass the scripts to the existing `c15tVue` plugin call in `src/main.ts`:

```ts title="src/main.ts"
import { c15tVue, manifest } from 'c15t/vue/vue-plugin';
import { scripts } from './consent-scripts';

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

Keep your existing `mode` and other options. The plugin starts one
script loader when the app mounts, after it has applied the visitor's stored
choice. Do not also call `createScriptLoader` from a component. See
[Vue scripts and embeds](/docs/frameworks/vue/scripts).

**Astro**

Add the scripts to the client entrypoint from the
[Astro quickstart](/docs/frameworks/astro/quickstart), `src/c15t.client.ts`,
which the integration finds on its own. Keep `astro.config.mjs` as it is.
If the module already exports scripts, combine the two arrays.

```ts title="src/c15t.client.ts"
import type { C15tClientOptionsExtension } from 'c15t/astro';
import { scripts } from './consent-scripts';

export default { scripts } satisfies C15tClientOptionsExtension;
```

Vendor helpers contain callbacks, and the integration options in
`astro.config.mjs` are serialized into the page, so do not put helpers in
the integration's `scripts` option. The integration passes the client
entrypoint to the one runtime every page shares, including across
`ClientRouter` navigation.

**Svelte**

Import the scripts in the component that owns your existing provider and
pass them as a top-level prop:

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

<ConsentProvider mode={manifest()} {scripts}>
  <!-- Keep your application, consent UI and preferences link here. -->
</ConsentProvider>
```

Retain the styles and consent UI from the [Svelte quickstart](/docs/frameworks/svelte/quickstart).
The provider owns the loader and disposes it on unmount.

**SvelteKit**

Add the scripts to the existing `ConsentRoot` in the root layout. Keep the
handle and the layout load from the [SvelteKit quickstart](/docs/frameworks/sveltekit/quickstart).

```svelte title="src/routes/+layout.svelte"
<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()}
  <!-- Keep your consent UI and preferences link here. -->
</ConsentRoot>
```

Import vendor helpers in the layout component, not in `+layout.server.ts`:
a server load cannot send functions to the browser. Prerendered, static and
SPA-mode pages use the same `scripts` prop. If you pass an externally owned
`runtime` to the provider, register scripts when creating that runtime instead.

**HTML**

The helpers in `@c15t/integrations` are ES modules that need a bundler. On a
page that loads the c15t script tag, paste the vendor's own snippet instead
and keep it inert until its category is allowed:

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

Use the category this guide names for the vendor. c15t runs the snippet
once that category is allowed, and reloads the page when the visitor
withdraws it. Helper options on this page, such as `loadMode`, do not apply
to a pasted snippet. See [HTML scripts](/docs/frameworks/html/scripts).

**JavaScript**

Pass the scripts to `init()` from `@c15t/browser`, next to your mode:

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

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

Keep the mode from your quickstart. With
`createConsentRuntime` from `c15t/runtime`, pass `scripts` to it instead.
A kernel you create yourself needs a loader from
`c15t/modules/script-loader`. Attach one loader per kernel. See
[JavaScript scripts](/docs/frameworks/javascript/scripts).

## Options

|Option|Default|Behavior|
|--|--|--|
|`tagId`|Required|Tag ID passed to `pintrk('load', ...)`. The helper trims it. Empty or whitespace-only values log an error and the script does not load.|
|`loadOptions`|None|Object passed as the third argument to `pintrk('load', ...)`, such as `em` or `external_id` for enhanced match. Pass user data only when your app has the permission it needs.|
|`trackPageVisit`|`true`|Queues `pintrk('page')` after `load`. Set `false` to send page visits yourself.|
|`scriptUrl`|`https://s.pinimg.com/ct/core.js`|Loader URL override. A blank value falls back to the default.|

## Loading and revocation

`pinterestTag` uses the `marketing` category. Before marketing is allowed, c15t
defines no `pintrk` function and loads nothing from Pinterest. When marketing
becomes allowed, the helper queues `load`, `pintrk('setconsent', true)` and
the page visit, then loads `core.js`.

On revocation the helper keeps the tag and calls
`pintrk('setconsent', false)`, which Pinterest documents as stopping events
and clearing its first-party storage. If the visitor allows marketing again
before the page reloads, the helper calls `pintrk('setconsent', true)`.

## Guard your own pintrk calls

The helper sends the page visit. Events your code sends, such as `checkout` or
`lead`, need their own check. After revocation `window.pintrk` still exists, so
its presence does not mean marketing is allowed. Check the permission first,
then that the tag has loaded:

```ts title="src/track-checkout.ts"
export function trackCheckout(marketingAllowed: boolean, orderId: string) {
	if (!marketingAllowed || typeof window.pintrk !== 'function') return;
	window.pintrk('track', 'checkout', {
		currency: 'USD',
		event_id: orderId,
		order_id: orderId,
		value: 99.99,
		line_items: [{ product_id: '1414', product_quantity: 1 }],
	});
}
```

Pass the current marketing permission from your framework, for example
`useConsent('marketing')` in React. Put product details in `line_items`, and
set `event_id` to deduplicate against the Conversions API. Pinterest reports
conversions only for its 20 event types. It keeps other event names for
audience targeting.

`@c15t/integrations/pinterest-tag` also exports `pinterestTagEvent`, a typed wrapper
around `pintrk('track', ...)`. It does nothing until `pintrk` exists and does
not check permission, so apply the same guard before calling it. Its optional
third argument receives Pinterest's `(didInit, error)` result.

## Verify the Pinterest Tag

After you allow marketing, `core.js` loads from `s.pinimg.com` and Pinterest
Tag Helper shows the page visit. Trigger one guarded event and check that Tag
Helper records it. Then revoke marketing. Until the page reloads, calling
`trackCheckout` sends nothing.

Test in a private window with an opt-in policy. Open DevTools Network, disable
the cache and filter by the vendor's domain:

1. Load the page. No request goes to the vendor before you choose.
2. Click Reject, then reload. There is still no vendor request.
3. Open Privacy settings and allow the helper's category. The vendor script
   loads without a page reload.
4. Turn the category off again and save. c15t reloads the page, and the new
   page makes no vendor request.

c15t reloads on revocation because removing a script element does not stop
code that already ran. The vendor's listeners, timers and queued events stay
alive until the page unloads. If you set `reloadOnConsentRevoked: false`, stop
the vendor yourself. Register a callback-only script whose `onConsentChange`
calls the vendor's opt-out API, as shown in
[custom integrations](/docs/integrations/building-integrations), and check the
permission before each of your own event calls. The reload does not delete
cookies the vendor already set; see
[clear on revocation for your framework](/docs/integrations/overview#vendor-switches-and-cookie-cleanup).

The helper sets `vendor` to its script ID, so once you declare that vendor a
visitor can turn it off inside an allowed category. See
[vendor consent for your framework](/docs/integrations/overview#vendor-switches-and-cookie-cleanup). The
[consent verification guide](/docs/guides/verify-consent) covers navigation,
expiry and hosting checks.
