Server-side tracking

ClickFunnels Classic → Meta CAPI

Register credentials

You need both from Meta Events Manager (same Business account that owns the pixel).

Pixel ID
- Open Events Manager.
- Go to Data sources and select your Pixel.
- Open Settings — the Pixel ID is the numeric ID (often 15–16 digits). Copy it into the field below.
Conversions API access token
- In the same pixel, open Settings.
- Find the Conversions API section (sometimes under “Set up direct integration”).
- Click Generate access token, copy the token immediately (Meta may only show it once), and paste it below.

If you do not see Conversions API, confirm you have admin access to the pixel and that the pixel is selected under the correct Meta Business.

Open your Funnel → Settings → Manage Your Funnel Webhooks.
Test URL: create a webhook with the validation URL above; run ClickFunnels test until it succeeds.
Production URL: create a webhook with the production URL, events purchase_created (and optionally purchase_updated); use default adapter/version.
After a test purchase, check Deliveries in ClickFunnels.
Deduplication (browser Pixel + server CAPI): If you fire the Meta Pixel on your thank-you page, Meta counts one Purchase only when both use the same event_id.
- Server (automatic): CAPI event_id from a stable purchase id in the webhook (id / purchase.id / purchase_id).
- Browser: fbq('track', 'Purchase', {}, { eventID: 'SAME_ID' }) with the same id.
- On the page: Expose the id via URL param, merge field, or custom JS. Without it, server-only events may double-count with the pixel.
- Verify: One test order → one deduplicated Purchase in Events Manager.
