These parameters consist of all required event data parameters and any additional data parameters the Conversions API needs to use for ads attribution and/or ads delivery optimization.

Website events shared using the Conversions API require the client_user_agent, action_source, and event_source_url parameters, while non-web events require only action_source. These parameters contribute to improving the quality of events used for ad delivery and may improve campaign performance.
