Error creating journal entries via API

1

Hi

I can authenticate okay but my journal entry generation request shown below fails with “journal_entries.code can’t be blank”. No mention of a code field in the docs. Any ideas?

Thanks

Jonathan

Hmm. Not sure what the story is here.
I tried again with a different set of journal entries and met with success.
