title: How to make a request using graphql-go
body: <p>I need to make a request to an external API which uses GraphQL using Go. To do so, I'm using the following client: <a href="https://github.com/graphql-go/graphql" rel="nofollow noreferrer">https://github.com/graphql-go/graphql</a> but the documentation is very limited and don't quite understand how to perform the request. My request is a simple mutation but again, don't know how to perform it.</p>
