|---|---|---|
| Runs in | The visitor's browser | Your server |

| Matching data | Cookies, plus optional hashed details | Hashed email or phone, IP, user agent, cookie ids |
| Consent | Needed where the law requires it | Same rules; server-side is not a loophole |

How to choose between Meta Pixel and Conversions API
- Use the Pixel for a quick start and for browsing events such as page views and add-to-cart.
- Add the Conversions API when sales or leads are confirmed on your server, or when Pixel data is missing conversions.
- Running both with a shared event id for deduplication is the setup Meta recommends.
