Facebook Conversion Api lets you sent Pixel events directly from your server. Server events are linked to a Meta Pixel ID and are processed like web events sent via Pixel. This means that web server events are used in measurement, reporting, and optimization in a similar way as browser Pixel events.

Event Field Mapping

Facebook conversion api events fields are classified into 4 groups in the mapping page.

  1. Server Event Parameters

    event_name and event_time are mandatory. action_source is also a required field, you can skip it if provided in the sync settings section.

  2. Customer Information Parameters

    The customer information parameters are a set of user identifiers you share alongside your event information. Facebook use this for customer matching purposes only. Castled hashes this info before sending to Facebook. You must provide a mapping for at least one of this parameter when creating the pipeline.

  3. Custom Data Parameters

    Use these parameters to send additional data for ads delivery optimization. There are a bunch of predefined custom data parameters.

  4. User Defined Custom Properties

    If you want to send any parameters in addition to the custom data parameters, you can use this section. A new custom property will be created corresponding to the name you provide.

More details about these fields and their types can be found in the Facebook conversion api paramaters doc.
