Answer 1

Your Regular Expression Extractor configuration should be like:

Reference name: Courselectureid (Could be anything)
Regular Expression: "courselectureid":(\d+)
Template: $1$
Match No.(0 For Random): 1

For Regex test see here: https://regex101.com/r/MdHaYq/1

Here, the total number of match found will be 4, but you need to extract only one of the values 1429. That's why Match No.(0 For Random): 1 is used. You could use the value 0, in that case, it will pick a match randomly. In you case, it will not have any impact as all the matches are returning the same value 1429.
