The current Events section in the Funnel only supports sending events to Meta, but it does allow for Conversions API usage, as well as sending of additional data typically not available with standard tag implementations.
To allow for the sending of data to different analytics/advertising platforms, but without requiring the resources to create custom implementations for every provider, I'd like to see a common events API that can be enabled from this tab for other platforms that can push the enriched data and events, even if this just utilises Google's Datalayer API.
This solution would be significantly more optimal than utilising current bandaid solutions such as intercepting other API calls (like form submissions) during the call and extrapolating the event/user data out from there, which could cause submission/platform issues if implemented incorrectly.
