Hi, thank you for your reply.
Looks like the link you've provided shows another option of retrieving an invoice (getting the binaries of the pdf as a string that can then be written into a local file), however, this can only come after the step we're still trying to figure out:
Look at your proposed solution, before you get to make that request, you have to go through
step 1 which is exactly what I was asking originally: "Retrieving invoices"
Following any of the many links in that page, I can see all the parameters I'm required to submit but the actual target, the URL to point those parameter to is nowhere to be found.
So
ListInvoicesRequest for that matter, the 4 parameters (customer_id, billing_setup, issue_year, issue_month) where do I send them to?
Hope I'm making myself clear.
Thanks.
