I am trying to use the test C# application included with the SDK. I can upload a text string and retrieve it just fine, but I cannot upload a file. I get the following error:
There was a mismatch between the signature in the request and the signature computed by the server.
The same Token and Shared Secret work for saving text, though. Is there a different kind of Token that I need to use for uploading a file?
To which test application are you referring? I'm not aware of a test application that's included with the release package. The latest official release package is here:
Can you get a wireshark capture of the request that fails?
