Missing Facebook Lead ID

M-Z — Fri, 10 May 2024 10:11:04 GMT

Hello,

I am trying to enhance FB Leads quality by doing Conversion Leads Integration. So when a Lead on Hubspot change "life stage" then it will be sent back to Meta to enhance the leads quality. The problem I am facing here is "Missing Lead ID". This integration can not be completed without the Lead ID. So I tried using Zapier and I can see the Lead ID in the first part of the Zap in Facebook. But I can not see it in the second part of the zap which is hubspot. In direct integration this is not possible either. Based on Meta advice, this issue comes from Hubspot. And with Hubspot I didn't get any feedback they simply ask me to pay to get their support!

To resolve the "Missing Lead ID" issue, start by verifying that the Lead ID is correctly captured in the first part of your Zap (Facebook Lead Ads trigger). Ensure that this data is being pulled accurately. Next, check the second part of your Zap (HubSpot action) to confirm that the Lead ID is being mapped and transferred properly. If the Lead ID isn't appearing in HubSpot, it might be due to how HubSpot is configured to handle incoming data. Since direct integration has similar issues, this suggests that HubSpot might be the source of the problem.

@HMir Thanks for your reply. It seems that Hubspot is the source of the problem. In the first part of the zap you can see the Lead ID but Its missing in the action step in Hubspot. They do that so to force you to pay for the professional hub package. This is why I am trying to find solutions in other CRM systems where I can use free of charge without having to pay a fortune!

When sending Meta Events, Hubspot is not including the Lead ID with the event data sharing. According the Meta, the Lead ID is the "gold standard" for matching contacts with Meta ads. As a result, Meta is only able to match around 50% of the contact events it receives, which results in poor ad optimization in Meta. Facebook provides a Lead ID with every Meta lead form (I see it in zapier), but Hubspot is not including this information in the lead syncing tab either. I can push the Lead ID into Hubspot via Zapier, but I'm still going to have an issue sending the events into Meta with Hubspot's event limitation via lifecycle stage changes. Could you please include the Lead ID when sending events so we can properly match the contacts to the Meta ads? See screenshots.

Hey @jditmer0 and Happy Wednesday!

That is right, currently, HubSpot’s Facebook conversion events can’t send the Meta “Lead ID” as a match key. We are using standard fields like email or phone for matching and don’t access custom properties, so even if you store the Lead ID elsewhere, it won’t be passed to Meta.

Here is the article about it: "Create and sync ad conversion events with your Meta Ads accounts using Meta's Conversion API".
