Hi,

We recently discovered that automationFacebook Lead forms is not always triggerd. After exporting leads from Facebook form and cross checking with Zapier history, we identified that certain number of leads comming from same form, campaign, ad set and even same add does not appear on Zapier histroy, meaning Zapier never received a webhook for it. While other pass to Zapier just fine.

Is any one experiencing same issue? Have you identified any patterns?

I’ve discovered that same issue already happened in 2024

and a bug assosiated with it was open on Meta developers platform https://developers.facebook.com/support/bugs/1130587701359392/

Unfortunatelly, it seems that only product owners can open platform related bugs on developers platform. Hope Zapier team could help us reopen this case with Meta.

Hi @fab_isaac, sorry to hear you're also being affected by this.

Sharing an update for everyone following along here: our engineers have now closed the bug report, as they determined the issue is on Facebook Lead Ads' end, with Facebook not consistently sending webhooks, rather than an issue with the Zapier integration itself.

If leads are still not coming through, the best next step is to contact Facebook’s support team directly with your Page ID and the timeframe when the missing leads were captured.

Thanks for your patience while we looked into this, and I'm sorry we couldn't provide a better outcome from our side. I'll leave this topic open for now in case anyone has any good news to share after reaching out to Facebook.

Hey all! 👋

Facebook has asked us to provide some more recent examples for them to investigate. Specifically they need your Page ID and example Lead IDs for leads that recently failed to be sent to your Zap.

If you're able to get some recent examples of missed leads, please share the IDs with me via private message rather than posting them here publicly and I’ll pass those on.
