Facebook Messenger trigger support conversations initiated from Click-to-Message Ads

Hi and welcome to the Community ​@Miwsictwo! 😁

I checked the New Message Sent to Page trigger and couldn’t see that message_referral field you’re after. Looking at Meta’s Webhook documentation it seems that the referral data isn’t returned with their Messages Webhook Event so that’s potentially why it’s not available with that trigger. They have a separate messaging_referrals webhook event which seems to contain the info you need. Though, that appears to only be for existing conversations, for new conversations they have a messaging_postbacks webhook event.

Since they appear to have webhook events that would give you that referral data, perhaps you could set up a Facebook app and subscribe it to the messaging_referrals and/or messaging_postbacks webhook events on Facebook’s end. Which would allow them to send a webhook direct to a Zap with that referral data. With that approach you’d want to try using a Catch Hook (Webhooks by Zapier) trigger instead of the New Message Sent to Page one. If you’re not familiar with how to use Webhooks triggers you can learn more here: Trigger Zaps from webhooks. Happy to help if you get stuck at all!
