Tip:

Always remember to replace API_SECRET in the Bearer Token and project-id in the URL with the correct values from the Apito console.
If you are unsure where to find your API secrets and endpoints for your project, visit this page.

import "context"

// create a client (safe to share across requests)
client := graphql.NewClient("https://api.apito.io/secured/graphql")

// make a request
req := graphql.NewRequest(`
    query ($key: String!) {
        items (id:$key) {
            field1
            field2
            field3
        }
    }
`)

// set any variables
req.Var("key", "value")

// set header fields
req.Header.Set("Authorization", "Bearer API_SECRET")

// define a Context for the request
ctx := context.Background()

// run it and capture the response
var respData ResponseStruct
if err := client.Run(ctx, req, &respData); err != nil {
    log.Fatal(err)
}
