++ `send_headers`
+
+  Provide this field to configure which request header names and values are included in trace data that's sent to Apollo Studio. Valid options are: `only` with an array, `except` with an array, `none`, `all`.
+
+  The default value is `none``, which means no header names or values are sent to Studio. This is a security measure to prevent sensitive data from potentially reaching the Router.
