Invoice attachment download problem.

Invoice attachment download problem.

Hello,
    I am using following zoho books documentation to get an invoice attachment using API.
https://www.zoho.com/books/api/v3/invoices/#get-an-invoice-attachment

Using above documentation method only latest attachment of invoice getting downloaded. There are no parameter available on documentation to download specific attachment of an invoice or download all attachments of an invoice.

Is there any way to download specific attachment of an invoice using API?
