You can also create a batch journal request by using the following endpoint. This is enabled on JNLC for now only.
Note that if there is an invalid account_id the whole batch operation will be canceled.
Every single request must be valid for the entire batch operation to succeed.
In the case of a successful request, the response will contain an array of journal objects with an extra attribute error_message in the case when a specific account fails to submit a journal.
