Need Help – Facebook Ads Not Counting Leads Sent via Conversions API (CAPI) and PIXEL

[supremeboy]

Hi everyone,


I'm currently running Facebook Ads and facing a frustrating issue with conversion tracking. Here's the setup:

Original Flow:​

1. A prospect clicks on the Facebook ad and lands on our landing page.
2. On the page, they click a CTA button that opens a WhatsApp chat.
3. All WhatsApp conversations are handled inside our CRM (via WhatsApp Business API).

The Problem:​

The Facebook Pixel was firing a “Lead” conversion as soon as the CTA button was clicked, even if the user never actually sent a WhatsApp message. This resulted in inflated lead numbers and prevented proper campaign optimization based on real leads (users who actually messaged us).

---

Our Solution:​

After days of testing, we built a new setup using n8n to automate everything and track a real Lead event only when a message is actually received in the CRM (i.e., when a lead is truly created). This event is then sent to Meta via Conversions API (CAPI).

Here's how the flow works:​

1. Trigger from CRM: As soon as a WhatsApp message is received, the CRM sends a webhook to n8n.
2. Send Lead Event to Meta: n8n captures the lead info (first name, last name, phone, IP address, FBC, FBP, FBCLID, user agent, external ID) and sends a "Lead" event to the Conversions API.

We are currently sending the following parameters to Meta:

• phone
• first_name
• last_name
• FBC
• FBP
• IP address
• user agent
• external_id

---

!! Current Issue: !!​

Everything works correctly on the n8n side. The event reaches Facebook Events Manager just fine and appears with all the correct parameters.


However, when we launch a Lead campaign, no conversions are being counted under “Results” in the campaign dashboard. So the Cost per Result remains empty, and the campaign doesn't seem to optimize based on the leads we’re actually sending via CAPI.

Our Questions:​

• Are we sending the correct event type? Should it be "Lead" or something else?
• Is it a campaign objective mismatch?
• Do we just need to wait for more data (only one lead has been received so far)?
• Or is there something we’re missing in the CAPI implementation or campaign setup?

Willing to Pay :​

If Facebook is not counting leads sent via CAPI and Pixel, you should:

Check your event configuration in Events Manager.

Make sure the Event ID is sent via both Pixel and CAPI to avoid duplicates or omissions.

Verify the domain and assign the correct event priority in your iOS 14+ configuration.

Use the Event Debugger to identify technical errors or missing data.

Proper technical syncing is key to ensuring data is properly recorded.
