Meta links, pixels, publishes and rejections: the usual suspects.
First, try disconnecting AdCat from Settings → Meta connection and then reconnecting through the OAuth flow. This clears any stale token and resolves most connection issues. If that doesn't fix it, check that your Meta Business account has admin access to the ad account you're trying to use and that AdCat is approved in Business Manager → Integrations. If you're still stuck after both, email hi@adcat.ai and we'll look at your account directly.
Start in Settings → Meta connection and confirm the right ad account and pixel are connected; the pixel ID there should match the one in your Meta Events Manager. Then make sure the pixel is live on your own site, on the page you're driving traffic to and not just your homepage. Events Manager shows whether Meta is receiving events, and the free Meta Pixel Helper Chrome extension tells you within seconds whether a page is sending them. New events can take up to a day to appear, so give it time before assuming something's broken.
Publishing failures almost always come down to one of three things: your Meta account isn't connected, no pixel is connected for a Sales or Leads goal, or there's no valid payment method in your Meta ad account. Check Settings → Meta connection for the first two (your ad account and pixel should both show there), and check Billing in your Meta Ads Manager for the payment method. If everything looks fine and you're still seeing an error, take a screenshot and send it to hi@adcat.ai so we can decode Meta's message for you.
Meta rejects ads for policy violations, most commonly prohibited content (firearms, supplements, certain financial products), misleading claims ("guaranteed results," before-and-after weight loss), or restricted categories that require special permissions (alcohol, dating, employment). AdCat flags common issues before you publish, but Meta runs its own review after submission, so some rejections only surface once the ad is live. You can read Meta's full policy at facebook.com/policies_center, and if you think a rejection is wrong you can request a manual review directly from your Meta Ads Manager.
