### Method Details

`create(parent, body=None, x__xgafv=None)`

    Creates a feed in a parent project/folder/organization to listen to its
    asset updates.

    Args:
      parent: string, Required. The name of the project/folder/organization where this feed
    should be created in. It can only be an organization number (such as
    "organizations/123"), a folder number (such as "folders/123"), a project ID
    (such as "projects/my-project-id")", or a project number (such as
    "projects/12345"). (required)
      body: object, The request body.
        The object takes the form of:

    { # Create asset feed request.
        "feedId": "A String", # Required. This is the client-assigned asset feed identifier and it needs to
            # be unique under a specific parent project/folder/organization.
