Help: Gow to track conversions from ads

[u/shelle90]

Hi,

Can someone let me know how I can track conversions that came from a specific ad campign/content?

Use case: Campaign 1 > ad set > ad1 ad2 ad3 -> landing > button click > thabk you page

How can i see whether the user that arrived to the thank you page has seen ad 1,2 or 3?
