for i in `seq 1 20`; do curl http://url; done

Or if you want to get timing information back, use ab:

ab -n 20 http://url/

You might be interested in Apache Bench tool which is basically used to do simple load testing.

example :

ab -n 500 -c 20 http://www.example.com/

n = total number of request, c = number of concurrent request

You could use URL sequence substitution with a dummy query string (if you want to use CURL and save a few keystrokes):

curl http://www.myurl.com/?[1-20]

If you have other query strings in your URL, assign the sequence to a throwaway variable:

curl http://www.myurl.com/?myVar=111&fakeVar=[1-20]

Check out the URL section on the man page: https://curl.haxx.se/docs/manpage.html

If you want to add an interval before executing the cron the next time you can add a sleep

for i in {1..100}; do echo $i && curl "http://URL" >> /tmp/output.log && sleep 120; done

You can use any bash looping constructs like FOR, with is compatible with Linux and Mac.

In your specific case you can define N iterations, with N is a number defining how many curl executions you want.

for n in {1..N}; do curl <arguments>; done

ex:

for n in {1..20}; do curl -d @notification.json -H 'Content-Type: application/json' localhost:3000/dispatcher/notify; done
