Facebook Ads Not Tracking Properly in BeMob with Zeydoo

[IMaRtinI]

Hey everyone,

I'm running Facebook Ads and tracking with BeMob for my campaigns on Zeydoo CPA Network. However, my Zeydoo manager pointed out that most of the traffic is coming with an empty ID (-), making it hard to optimize or check traffic quality.
I logged into Bemob and indeed found an unknown source in all my campaigns called "empty." The majority of clicks and conversions are attributed to it.

Issue as Reported by Zeydoo Manager:
"What is really important for you is paying all your attention to transferring sub sources to us. You need to check settings of parameter var on your side because we get traffic mostly from empty ID, like -. And because of that, we can't do really deep optimization or quality check.

My Current Setup (Facebook Ads URL Parameters)
In Facebook Ads Manager, I added this in the "Tracking Parameters" section:
fbclid={fbclid}&ad_id={{ad.id}}&adset_id={{adset.id}}&campaign_id={{campaign.id}}&ad_name={{ad.name}}&adset_name={{adset.name}}&campaign_name={{campaign.name}}

Also i tried this as well:
custom1={{ad.id}}&var={{campaign.name}}&ymid={{fbclid}}&ad_id={{ad.id}}&adset_id={{adset.id}}&campaign_id={{campaign.id}}&ad_name={{ad.name}}&adset_name={{adset.name}}&campaign_name={{campaign.name}}

for the offer link i add these tokens:

And tried this as well:

But nothing works. Even when I go
