The GraphQL query, as a string.

Name-value pairs giving API parameters. Will be matched into endpoint placeholders, sent as query parameters in GET requests, and as a JSON body of POST requests. If there is only one unnamed parameter, and it is a raw vector, then it will not be JSON encoded, but sent as raw data, as is. This can be used for example to add assets to releases. Named NULL values are silently dropped. For GET requests, named NA values trigger an error. For other methods, named NA values are included in the body of the request, as JSON null.
