Is there anyway to get at my clients Tax Agencies when creating an invoice?
I'm using the C# IPP DevKit against QBO.
I don't see it mentioned in the documentation, however I can't imagine I'll be required to hard code all my clients tax tables into my app as that is silly.
What you're looking for (the list of tax rates) is not really what you're asking for (tax agencies).
In any case, this thread answers your question: https://idnforums.intuit.com/messageview.aspx?catid=87&threadid=18930&enterthread=y
Unfortunately, the answer is:
Thus, what you're trying to do can't be done right now.
I am not sure if you are using QuickBooks Online or for Windows. Either way, the Tax Agency would most likely be a Vendor in the customer's QuickBooks file.
So use the vendor query in the devkit to pull the list of vendor's and you can later use the CDCasOf filter to get the new or modified vendors to keep things up to date.
The supported objects and operations are listed here for future reference.
