+### `priv_traceTransaction`
+
+Provides a [transaction trace](../../../public-networks/reference/api#trace_transaction) for a private transaction. 
+
+#### Parameters
+
+- `privacyGroupId`: _string_ - the privacy group ID associated with the transaction
+
+- `transactionHash`: _string_ - the hash of the private transaction to trace
+
+#### Returns
+
+`result`: _array_ of _objects_ - list of [calls to other contracts](../../../public-networks/reference/trace-types.md#trace) containing one object per call, in the order called by the transaction. 
+If revert reason is enabled with [`--revert-reason-enabled`](../../../public-networks/reference/cli/options.md#revert-reason-enabled), the returned list items include the [revert reason](../../how-to/send-transactions/revert-reason.md).
