# Update task input

`PUT /v2/actor-tasks/{actorTaskId}/input`

Updates the input of a task using values specified by an object passed as
JSON in the PUT payload.

If the object does not define a specific property, its value is not updated.

The response is the full task input as returned by the
[Get task input](#/reference/tasks/task-input-object/get-task-input) endpoint.

The request needs to specify the `Content-Type: application/json` HTTP
header!

When providing your API authentication token, we recommend using the
request's `Authorization` header, rather than the URL. ([More
info](#/introduction/authentication)).
