I don't mean to slight your efforts (I will be happy to show you how to do this) but my humorous reply might help you and others understand why you don't want to do it this way and what is really happening when you "redirect".
It is obvious the formula is gigantic so I will not even comment on this further.
Let's say you needed to make a recipe with 22 ingredient and you have to go shopping for everything. Would you prefer to make 22 trips from your car to the checkout purchasing one item at a time or would you just make one trip and purchase all 22 ingredients at once?
Instead of using ?a=API_AddRecord 22 times you want to use ?a=API_ImportFromCSV once with CSV representing 22 records of data..
I will put it on my todo list to show you the code but I have other stuff to attend to now.
