Help old API repeat params not working anymore

[Nicholashuber]

Adding these params to my urls was working to create multiple events repeating daily as per directions from the developer over email. As of this year it seems to have stopped working. I cant seem to get in contact with the developer :( I've been going through older bower packages and the npm packages but I've found nothing. Is it possible these params are named differently? Any help or insight is appreciated.
