Frequently Asked Questions

Why does my query fail with a CORS error?▼

Browsers enforce CORS on HTTP requests. Ensure your GraphQL server includes `Access-Control-Allow-Origin: *` or allows your domain.

Can I test mutations?▼

Yes! Simply write your mutation syntax in the query pane and provide the input variables in the JSON variables pane.
