@JensDeveloper - Ultra tasks consume incoming documents. I believe what you want to do is POST data to the Ultra task, not pass it as URL query parameters. See the Ultra Pipeline best practices documentation final bullet point in regards to your situation with trying to parse the pipeline parameters:
- You cannot change Pipeline parameters at run time. These parameters are specified in the Pipeline itself or when the task is created. They are set at pipeline startup, which only happens on initiation, not per document.
