Sending User Data Parameters via Pixel

I have some user data parameters from Facebook's Marketing API (https://developers.facebook.com/docs/marketing-api/server-side-api/parameters/user-data#external-id) that I wish to send using Pixel (fbq function)

Let's take one of the user data parameter - external_id I am currently doing something like this -

fbq('track', 'AddToCart', {external_id: 1234})

The documentation on the aforementioned url states that you can send these values using fbq('init') function, but I wasn't sure if its applicable with fbq('track') function too.

On another note, recently I got this mail from facebook that "Your server is sending the external_id parameter for your AddToCart event inside the custom_data field section of your payload. External_id is invalid unless it is sent as user data field"

What could be the reason for it? the documentation states you don't need to wrap external_id inside user_data field if sending through pixel. Is this issue message incorrect?

It could be tricky to init fbq many times. Another way is to add params to user is set user data:

window.fbq("set", "userData", parameters);

where param could be:

{
      'em':'[email protected]', // Email
      'external_id': user12345 // User ID
      }

Maybe this helps: https://developers.facebook.com/docs/meta-pixel/guides/track-multiple-events

Not like if it is documented anywhere or is recommended by Facebook, but you can call init again at a later point in time with additional info.

So you can call init the normal default way first:

fbq('init', 'XXXXX')

And at a later point in time, when you have obtained additional user data, you can call init again basically enriching the already running fbq instance with additional data:

fbq('init', 'XXXXX', { external_id: 1234, em: '[email protected]' } )

Only caveat is that you have to send an event after this additional init call, otherwise the provided data will not be sent to Facebook.

I didn't have any issues passing the external_id. Maybe look at the snippet, you might have an error in there. Here's what I am using for the Page View event.

<script>
  !function(f,b,e,v,n,t,s)
  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
  n.callMethod.apply(n,arguments):n.queue.push(arguments)};
  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
  n.queue=[];t=b.createElement(e);t.async=!0;
  t.src=v;s=b.getElementsByTagName(e)[0];
  s.parentNode.insertBefore(t,s)}(window, document,'script',
  'https://connect.facebook.net/en_US/fbevents.js');
  fbq('init', 'XXXXXXXXXXXXXXX', {
      'em':'[email protected]', // Email
      'external_id': user12345 // User ID
      });
  fbq('track', 'PageView');
</script>
