CrakRevenue postback URL issues with server-side tracking?

hey everyone, i'm trying to integrate server-side tracking for a CrakRevenue offer, and i'm hitting a wall.

• the postback URL isn't firing consistently, particularly when i'm trying to pass custom subid parameters for more granular conversion tracking.
• i've checked the token placement and my server-side logic for `subid` capture, but it still feels like i'm missing something fundamental.

any insights on common misconfigurations or specific quirks with CrakRevenue's server-side postback integration would be super helpful. thanks in advance!
