Fb_login_id via Stape.io Data Tag

Facebook Conversion API

Hello

I would like to send the fb_login_id with the Data Tag. I only found one parameter for GA4 (user_data.fb_login_id) in the Facebook documentation. How can this work with the data tag?

Thanks
Stefan

Hi @Stefan_Kleinberger!

Just add the fb_login_id to the Data Tag as an Event Parameter under the Event Data section. Like this:

The Facebook Tag template from Stape will automatically pick it up and add it to the corresponding field when sending the event.

Hi @giovaniortolani
Thanks for the info.
My information is that the value of fb_login_id is only available if you’re logged into Facebook via the website. I’ve read that you can also send a fictitious value. So, for testing purposes, I sent a constant value stored in a cookie. This significantly increased the event quality score in META. Is this a sensible/possible approach?

Best Stefan

Hi @Stefan_Kleinberger,

Is this a sensible/possible approach?

I would advise against doing that. While it may increase the event quality score on the interface, it can disrupt the data further along for several reasons: 1) this fictitious value does not exist in Meta’s user databases; 2) it is not linked to a real user; and 3) Meta may assume that all these different events are associated with the same user. Therefore, I recommend sending the value only if it is a real value tied to an actual user.

Thanks @giovaniortolani that sounds reasonable
