Detailed description of issue
I’ve successfully merged XFDF in PDF using the REST API through a POST request. However, when I attempted to implement the same functionality in .NET by calling the REST API, I encountered an error. The error message reads: "Code 20: Invalid input. I’ve tried different PDF files, but the error remains the same every time.
Expected behaviour
It should merge XFDF in PDF and return PDF file.
Does your issue happen with every document, or just one?
