Webhook capability in Survey123 is very helpful to automate process without make a code. you can follow this link for the details : Automating workflows with Survey123 and Microsoft Power Automate (fomerly known as Microsoft Flow)
I got some challenges when use it in Microsoft Flow especially about time and date.
- originally time and date from survey123 is EPOCH format.
- by default time zone form survey123 is UTC.
- I have needs to display time and date in proper string format.
Convert EPOCH to YYYY/MM/DD HH:mm:ss
if you access time and date from field directly from dynamic content, it will display epoch time. to show time and date as YYYY/MM/DD HH:mm:sss you can use expression instead of dynamic content.
