Match Facebook pageviews with offline event settings?

Question

I would like to use offline conversion data to create a custom audience that I can map to visitors to my site. I am currently trying to do this:

• Using the Facebook pixel (fbevents.js) to track users, pass extern_id with our unique user ID during the init call, and then view page views as follows:

   fbq('init', '1234567890', {extern_id: UNIQUE_USER_ID}); fbq('track', 'PageView'); 

• Later uploading offline event data using extern_id people who made purchases

But Facebook gives me a 0% record match speed for an offline event (I have ~ 150,000 page views and several thousand purchases if that matters). Has anyone succeeded in matching only with extern_id or does Facebook require more user data?

Answer 1

I spent several hours on this and from what I can collect, offline events only work in conjunction with Facebook ads. Thus, your uploaded data is only associated with ads in your account, and not with the Facebook pixel.

Answer 2

Guy S - have you ever found a solution to your problem? We are trying to trigger transaction events for offline conversions - where we know what the user ID was, etc. - but we cannot find the link for Extern_id or Lead_id to run.

We even consider replacing session cookies for events, but I suspect that they are unique for each session, so they may not work

Answer 3

You must pass external_id instead of extern_id in the fbq init event.

 fbq('init', '1234567890', {extern_id: UNIQUE_USER_ID}); // Incorrect fbq('init', '1234567890', {external_id: UNIQUE_USER_ID}); // Correct
