Hoppscotch allows you to pass variables in the query to fetch data dynamically. To demonstrate the use of variables, let’s write a query to get countries by their name and continent. For example, we will fetch the details of “Bahrain” from the “Asia” continent.

​
Variables

Go to the variables section and define the variable. 
{
  "countryName": "Bahrain",
  "continentCode": "AS"
}

​
Using the variable in the query

Now create a query getCountries with variables as shown below: 
  query getCountries($countryName: String!, $continentCode: String!) {
    countries(filter: {name: {eq: $countryName}, continent: {eq: $continentCode}}) {
      name
      continent {
        name
      }
      code
      emoji
      currencies
    }
  }
Hoppscotch will retrieve the value of the variable and execute the query to get the below response. 
  {
    "data": {
      "countries": [
        {
          "name": "Bahrain",
          "continent": {
            "name": "Asia"
          },
          "code": "BH",
          "emoji": "🇧🇭",
          "currencies": [
            "BHD"
          ]
        }
      ]
    }
  }
