Run request many times with different query params as variable

Oh sorry I’ve created :

[
   {
      "dateFromStr":"2020-07-12",
      "dateToStr":"2020-07-12"
   },
   {
      "dateFromStr":"2020-07-15",
      "dateToStr":"2020-07-15"
   },
   {
      "dateFromStr":"2020-07-18",
      "dateToStr":"2020-07-18 "
   },
   {
      "dateFromStr":"2020-07-20",
      "dateToStr":"2020-07-20"
   }
]

Then you would need to use those key names as the variable names in the Collection.

ui/community/overview?dateFromStr={{dateFromStr}}&dateToStr={{dateToStr}}

Okay. But Is it okay that I don’t have variables with name as {{from}} and {{to}} in environment ? And it works
My file json

[{
  "from": "2020-07-12",
  "to": "2020-07-12"
}, {
  "from": "2020-07-15",
  "to": "2020-07-15"
}, {
  "from": "2020-07-18",
  "to": "2020-07-18"
}, {
  "from": "2020-07-20",
  "to": "2020-07-20"
}]

If a variable is placed in the collection with the same name as something from a datafile, it will be read from there. If you have a variable and it doesn’t resolve to anything, the raw string value will be used.

Variables at different levels will be used over others, if they have the same name

If a variable with the same name is declared in two different scopes, the value stored in the variable with narrowest scope will be used

The easiest way to answer your own questions when it comes to knowing if something works or not…is to simply try it out and see it for yourself :grin:
