I am trying to pull invoices by Accounts and have not managed to find a way to link the two. Am I missing something? 
I tried through Contacts but it doesn't seem to have an Account or Account ID to match
I am using Pyxero for this, however this doesn't seem relevant, more so the data from xero api.
Thanks
I've figured it out - these details only appear when pulling an invoice one by one or paginated in the line items column.
Xero Api matching Accounts with Invoices
