Thanks for presenting that idea. I tried it out right away. For some of the questions, I created Yes/No answer choices. Then, after that, I added an open-ended question asking for a "Course Name." The intention was to pre-fill something like "Introduction to IT" in that field, without showing it to the respondent when presenting the form.
First, I set up the branching logic so that either Yes/No choice would skip to the end of the form. When I tried retrieving the pre-filled URL, the last question wasn't displayed on the input screen. So it doesn't seem possible to pre-populate that string beforehand. Since the branching is set to skip that question regardless of the Yes/No selection, there doesn't seem to be a way to embed a response into that hidden question field.
