A Facebook Pixel ID is the unique number that identifies your Meta Pixel, the code that reports website events to Meta. It tells Meta which of your data an event belongs to, and it is what platforms and partners ask for when you connect your tracking.
Where to find it
Meta says a new ID is created when you name and create a Pixel, and that it is viewable in Events Manager. In Events Manager, the Settings tab lets you view the ID and owner of your data, as Meta's Events Manager page describes. Our answer on finding your Facebook Pixel ID walks through it step by step.

- Platform integrations. Store and website platforms ask for the ID to connect your Pixel.
- Tag managers. A tag manager needs the ID in the Pixel tag.
- Conversions API. Meta says to use the same Pixel ID for browser and server events if you already run a Pixel. See the Conversions API.
- Agencies and partners. Sharing the ID is how a partner is pointed at the right data.
- Testing. Matching the ID on your site to the one in Events Manager is the first check when events don't show up. A wrong or old ID is a common cause.
Example. A bakery with an online store asks a freelancer to set up tracking. The owner opens Events Manager, copies the ID from the Settings tab and sends it. The freelancer pastes it into the store's Pixel field, and test events appear in Events Manager.
In Madgicx. Madgicx Cloud Tracking hosts Meta's Conversions API Gateway and Signals Gateway for the advertiser and sends conversions to Meta from the server, so the same Pixel ID can feed both browser and server events.
