monitoring outgoing requests and the request body from the script

Question

Computer networks

Good afternoon

There is a script from the site that generates requests to the server on port 80 or 443.
There is a need to view the full body of the request that the script generates, so that something like this can be seen:

PUT http://example.com/api/v2/prv/2042/bills/BILL-1
Accept: text/json
Authorization: Basic MjA0Mjp0ZXN0Cg==
Content-Type: application/x-www-form-urlencoded; charset=utf-8

user=tel%3A%2B79031234567&amount=10.0&ccy=RUB&comment=test&lifetime
=2012-11-25T09%3A00%3A00

I understand that this can be done using wireshark, or even using tcpdump.
But I can’t find the right key + I would like to somehow free myself from unnecessary information.

thank you in advance
