# Meta Consent API

> Send consent state to the Meta (Facebook/Instagram) Pixel.

The Meta Consent API integration tells the Meta Pixel — used by Facebook and Instagram ads — whether the visitor has consented to advertising tracking. When the integration is enabled, CookieChimp calls `fbq('consent', 'grant')` or `fbq('consent', 'revoke')` automatically as the user's preferences change.

## Prerequisites

* A Meta Pixel installed on your site.
* A category or service in CookieChimp that represents Meta advertising consent (most accounts map this to the **marketing** category or a **Facebook Pixel** vendor).

## How do I enable it?

<Steps>
  <Step title="Open the Integrations page">
    Go to **Integrations** in your CookieChimp dashboard and find the Meta Consent API card.
  </Step>

  <Step title="Toggle it on">
    CookieChimp will push consent state to the Meta Pixel on page load and whenever the visitor updates their choices.
  </Step>
</Steps>

## How do I verify it's working?

1. Install Meta's [Pixel Helper](https://www.facebook.com/business/help/198406697184603) browser extension.
2. Open your site and decline marketing consent. Pixel Helper should show the pixel in a **consent revoked** state and no events should fire.
3. Accept marketing consent and reload. The pixel should now report as **active** and events should fire normally.
