Use these parameters with the Conversions API. These parameters consist of all required event data parameters and any additional data parameters to use for ads attribution and/or ads delivery optimization.
Website events shared using the Conversions API require the following data parameters:
event_source_url, 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.
