### About input objects
|
|
|
|
[Input objects](https://graphql.github.io/graphql-spec/June2018/#sec-Input-Objects) can be described as "composable objects" because they include a set of input fields that define the object.
|
|
|
|
For example, [`CommitAuthor`](/v4/input_object/commitauthor/) takes a field called `emails`. Providing a value for `emails` transforms `CommitAuthor` into a list of `User` objects containing that email address. Note that [objects](/v4/object) **may** have input objects, whereas [mutations](/v4/mutation) **require** input objects.

|
For more information, see "[About mutations](/v4/guides/forming-calls#about-mutations)."
