Quickbooks Online filtering with Signpost returns 401 error
问题 I was able to get Signpost work with QuickBooks Online using HttpPost. However when I tried querying with filters, I got 401 error every time. After contacting support, I was informed that this is a known bug. They pointed me to an example in C#. I am using Signpost oauth library in Java. The C# example doesn't make sense to me since I don't have those functions available in Signpost. Also I don't understand what exactly I need to do. One side note: I had to use HttpClient for this content
