We do not capture headers by default. 


However, you can capture trace IDs in two ways:

1. Add a trace ID to a request by adding the x-emb-trace-id header with the trace ID value.

2A. For Android, if the ID is already present in the request in a different header, set the name of the header in the embrace-config.json file with the networking[trace_id_header] setting. 


2B. For iOS, if the ID is already present in the request as a different header, set the name of the header in the Embrace-Info.plist file with the TRACE_ID_HEADER_NAME field.

After implementation, trace IDs will appear in the expanded view of a networking event on a user timeline.



Please note that trace IDs longer than 64 characters will be truncated.
