Question

In Segment the Facebook Conversions API Actions destination, can I map Meta’s AppendValue event original_event_data parameter?

Environment

Answer

No. The Facebook Conversions API Actions destination mapping does not currently support sending original_event_data as a separate nested object for Meta’s AppendValue event.

Meta expects original_event_data to be sent as its own nested object. This field is not available in the current mapping configuration.

As a workaround, you can use a Destination Function, optionally with Destination Filters, to send events that require a custom Meta Conversions API payload structure.
