🌪 Variables

You can add variables to an Airstack GraphQL query to provide dynamic inputs.

To do so, simply define the variable with $ prefix and specify the correct typing.

As an example, below is shown on how a query looks like after and before adding variable to an Airstack query:

{% tabs %} {% tab title="After" %}

query MyQuery($tokenAddress: Address) { # Define variable on the top level with the correct typing
  TokenBalances(
    input: {
      filter: {
        tokenAddress: {
          _eq: $tokenAddress # Variable as an input
        }
      },
      blockchain: ethereum
    }
  ) {
    TokenBalance {
      owner {
        addresses
        domains {
          isPrimary
          name
        }
        socials {
          dappName
          profileName
        }
        xmtp {
          isXMTPEnabled
        }
      }
    }
  }
}

{% endtab %}

{% tab title="Before" %}

query MyQuery {
  TokenBalances(
    input: {
      filter: {
        tokenAddress: {
          _eq: "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D"
        }
      },
      blockchain: ethereum
    }
  ) {
    TokenBalance {
      owner {
        addresses
        domains {
          isPrimary
          name
        }
        socials {
          dappName
          profileName
        }
        xmtp {
          isXMTPEnabled
        }
      }
    }
  }
}

{% endtab %} {% endtabs %}
