...GraphQL is a strongly typed Api query language that provides an alternative to REST. It allows clients to define the structure of the data required, and exactly the same structure of the data is returned from the server. This avoids both the problems of over and under-fetching data, while also allowing for a more powerful and flexible Api. You can omit the variables object and instead hard-code your values inside your query, however, this is not recommended past the simplest of queries.
