Runs a function in an Apps Script project. The script project must be deployed for use with the
Apps Script API and the calling application must share the same Cloud Platform project. This
method requires authorization with an OAuth 2.0 token that includes at least one of the scopes
listed in the [Authorization](#authorization-scopes) section; script projects that do not require
authorization cannot be executed through this API. To find the correct scopes to include in the
authentication token, open the script project **Overview** page and scroll down to "Project OAuth
Scopes." The error `403, PERMISSION_DENIED: The caller does not have permission` indicates that
the Cloud Platform project used to authorize the request is not the same as the one used by the
script.
Create a request for the method "scripts.run".
This request holds the parameters needed by the script server. After setting any optional
parameters, call the
AbstractGoogleClientRequest.execute()
method to invoke the remote operation.
