When everyone on YouTube has interfaces that definitely do NOT appear to you :/
I was supposed to create my pixel, give it a cute lil name and then test events ( Facebook ).
But NOOO ofc I would get a ton of issues in the process, everyone is able to connect their pixels safely but it took Facebook more than what, 4 days now ? To kindly inform me that:
Server external ID not matching to pixel external ID
You're sending the external_ID parameter for your PageView event from your server, but you're not sending the external_ID parameter for this event from your pixel. If you send external_ID for an event from your server, you must send it from your pixel as well in order for that event to be valid.
How am I even supposed to know how to fix that ! I just started learning programming, the only thing I know how to do is use Linux and write a ciao mundo C program. Now my store was supposed to be launched a week ago and I am still looking for solutions to this. Ugh.

When everyone is already ahead in programming languages and you're still lagging behind.
