Use case: We are already using CAPI so we don't need a new implementation
Well, that's great to know! I would still recommend you to double check if CAPI is live and working well for you. To do that, can you go to Snap events manager under your Ads manager interface and check if you see events coming in via Conversions API. Also check the EQS scores for each event. If EQS is above 6.0 and no warnings are shown, then your CAPI is working fine! If not, let's dicuss what we can do to improve the implementation for you.
