GraphQL API Salesforce

[@awesomekj5812]

Is there a seperate extnesion or software where we have to write our GraphQL query to fetch data ?

To check whether your query syntax is correct or not you can use Altair (used in this video as well). But if you are sure you query syntax is correct you can use Postman or LWC component to fetch the data.
