For clarity, that text means “the parameter(s) that were sent”, not “the parameter named sent”
The parameter(s) can be found after the ?, so reports%5B...... very long .... 2021-01-24
,
Then split them by &
And then you have name/value pairs split by =
You accidentally picked a complex example with lots of parameters, you can replace %5B with [ and %5D with ]
So in this example
-
reports[consolidated_page_views][facets]
→past_period
-
reports[consolidated_page_views][start_date]
→2021-12-24
and so on.
