Activate tracking (3 steps)

1. Set the Pixel on the account — in Accounts → Assets, pick the Meta Pixel (optionally TikTok).
2. Activate — in the Tracking tab, click "Activate tracking".
3. Add the code to the site — copy the snippet from Step 1 into <head>. For stores, see your platform guide.

Then check in Tracking → Tracking health that events come in. See Verify & test.
