Query parameters help you to filter and request specific data from an API endpoint.

You can add query parameters in two ways:

  1. Add them in the URL.
  2. Add them in the parameters tab.

​
Adding parameters in the URL

To add a parameter in the URL, append ? at the end of the URL and add a parameter in key=value format.

You can add multiple parameters by separating them using &.

For example, the below URL is filtered to get the data of the first three Pokemon.

https://pokeapi.co/api/v2/pokemon/?offset=6&limit=3

For which you will get a similar response:

{
  "count": 1281,
  "next": "https://pokeapi.co/api/v2/pokemon?offset=9&limit=3",
  "previous": "https://pokeapi.co/api/v2/pokemon?offset=3&limit=3",
  "results": [
    {
      "name": "squirtle",
      "url": "https://pokeapi.co/api/v2/pokemon/7/"
    },
    {
      "name": "wartortle",
      "url": "https://pokeapi.co/api/v2/pokemon/8/"
    },
    {
      "name": "blastoise",
      "url": "https://pokeapi.co/api/v2/pokemon/9/"
    }
  ]
}

​
Using the parameters tab

You can use the Parameters tab to set key-value pairs for your API requests. This tab also lets you add a description for each parameter, helping you provide a clear explanation of what each parameter does and why it’s important.

Hoppscotch also offers a Bulk edit feature, allowing you to add or modify multiple request parameters at once, with each key-value pair on a new line separated by a colon (:). For example,

param1: value1
param2: value2
# param3: value3

Try using the parameters tab to see if you get the same response as adding parameters in the URL.
