Parameters

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: client_user_agent, action_source, and 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.

Register for the webinar: ‘How to Use Facebook’s Conversions API: A Developer's Guide’ on Wednesday, June 16th. Facebook experts will guide you step-by-step through implementing the Conversions API and best practices. A “Conversions API Direct Integration Playbook” will be sent to registered participants following the webinar.
