How this request works:

Pre-request script

Sets a starting timestamp (now, minus 10 minutes)
Initialize a loop counter
Sets the timestamp of the current loop based on loop counter, and sets a variable used in the request body
Increments the counter

Test script

Check the loop counter, and loop the current request if counter < 71 (70 iterations)
