Is there any way to see the API logs in Piwik, I mean pure API call logs? I want to see what is being passed to Piwik. It is tracking correctly abandoned carts and lost cash for those. But for active orders the only data missing is Revenue. It’s not there. I am passing it in as the GET variable ‘revenue’. So it should be there.
You could try to enable debugging for the tracker: I'm a developer, how do I enable logging (and / or SQL profiling) in Piwik? - Analytics Platform - Matomo
Or enable log at “DEBUG” level with file logging, it will log all SQL queries. Watch out, that’s a lot of data! Turn it off afterwards.
