GraphQL Spec
Read about :spec:`input objects <Input-Objects>`.
In some cases, it is desirable for a query to include arguments with more complex data than a single value. A typical example would be passing a bundle of values as part of a :doc:`mutation <mutations>` operation (rather than an unmanageable number of individual field arguments).
Input objects are defined like ordinary objects, with a number of restrictions:
- Field types are limited to scalars, enums, and input objects (or list and non-null wrappers around those types)
- There are no field resolvers for input objects; these are values passed in their entirety from the client to the server
- Input objects do not implement interfaces
Input objects are defined as keys of the top-level :input-objects key in the schema.
