Get Invoice list api does not contain line items array?

Get Invoice list api does not contain line items array?

Hi Team,

                We are integrating our app with Zoho books via apis. We observed that in order to get invoices data we made a call to get invoice list api. We found that the response does not contain line items for each of the invoices retrieved. To get around this issue we get all invoices first and then get each invoice details. The issue with this approach is that our api calls increase many folds. Can you recommend any other efficient way to get invoice list and it line items together in one api call?

Thanks,
Jiten
