# Meta/Facebook pixel
To manage Meta pixel consent with AppConsent, we'll create and configure an extra vendor, then trigger a tag containing the Meta pixel code based on the user's consent.
## Extra vendor "Meta" configuration
1. Create or edit your website source, then turn on [Enable Meta Consent Mode](/configuration/step-2-create-a-notice/2.1.-create-a-source.md#meta-consent-mode) under Advanced settings. The Meta global extra vendor and its purposes are added to the source.
2. Save the source.
3. After creating a notice for this source, go to its Implementation section. The integration script now contains the Meta pixel base code. Replace {your-pixel-id-goes-here} with your own pixel ID, then add the script to the section `` of all your HTML pages.
{% hint style="warning" %}
**Do not install the pixel twice**
The Facebook pixel base code must appear only once on a page. If the pixel is already installed on your website, remove the block from the integration script before adding it. Two installations on the same page would result in duplicated events.
{% endhint %}
## Configuration in Google Tag Manager
To configure your tag according to user consent, see page : [Control your Extra vendors](/configuration/step-3-notice-implementation-web-app-tv/google-gtm/control-your-extra-vendors-finely.md)
