-`serverCodeFn` is the async function that will be executed on the **server side** when the action is invoked. If input validation fails, or execution gets halted in a middleware function, the server code function will not be called.
+`serverCodeFn` is the async function of type [`ServerCodeFn`](/docs/types#servercodefn)/[`StateServerCodeFn`](/docs/types#stateservercodefn) that will be executed on the **server side** when the action is invoked. If input validation fails, or execution gets halted in a middleware function, the server code function will not be called.
 
 In the case of a stateful safe action, `serverCodeFn` will also receive the `prevResult` as a property of the second argument (`utils` object) from the previous action execution, thanks to the [`useStateAction`](/docs/execution/hooks/usestateaction) hook (that uses React's [`useActionState`](https://react.dev/reference/react/useActionState) hook under the hood).
