How to Automate "Prepare Form" w/Auto Detection on PDF?

I'm trying to help a client take a rich text file (.rtf) and turn it into a fillable PDF. Here are my steps thus far:

1. Open .rtf in Word, save as Adobe PDF.
2. Open PDF in Acrobat Pro DC and select "Prepare Form"
3. Use Auto Detect to create fields (works flawlessly).
4. Manually rename fields (need to map field names to my application).

I'm writing a web application in GO that will fill these PDFs with data from a PostgreSQL db. Problem is, my clients get these .rtf files from their clients all the time, so I need to automate as much of this as possible. In a perfect world, I'd be able to automate all 4 steps above. My biggest concern is steps 2-4.

I've been trying to research the Acrobat DC SDK to see what I can do, but the documentation isn't the easiest. Any ideas?
