Template for post/put request

[khlilturki97]

Hi, while working with team mate, I was asked to give a template for each POST/PUT request, for example if i have a POST route /user, api tester should show something like

{
  "first_name":"string",
  "last_name":"string"
}

What i mean, is something that allows another developper to know what payload he should send

Thanks
