 The following optional parameters are supported:
 - `namespace` - set custom namespace for endpoint
+- `params` - object containing default parameters for the action (default: `{}`)
 
 If you pass in an array for the first parameter, the `create` call will be executed for each array item. The function returns a Promise which resolves with the results when all operations have finished.
