SMS Distribution via API

Deepak or anyone else who can help:
I'm working on a longitudinal study where we want to send daily qualtrics surveys via SMS to participants for a 10 week period. We would like to automate the sending of this survey for the entire 10 weeks. Ideally, we would like to randomize at what time the surveys are send daily. I looked at the sample request below and am wondering if there is custom code we can write for sendDate so as to automate survey invites being sent via SMS for a 10 week period.
Greatly appreciate any input!
Thanks!
