Payload Helper

Beginning February 15th, 2021, website events shared using Conversions API will require the following data parameters: client_user_agent, action_source, and event_source_url, while non-web events will require only action_source. These parameters contribute to improving the quality of events used for ad delivery and may improve campaign performance.

Fill out the required and recommended data parameter fields to see how your payload should be structured when it's sent to Facebook from your server.
