# Use with Promises Resolved with Null Values

If a promise is resolved with a `null` or `undefined` value, the fullfilled action will not include a payload property. This is because actions describe changes in state. Consider the following two actions:

```
// A
{
 type: 'ACTION`,
 meta: ...
}

// B
{
 type: 'ACTION'
 payload: null,
 meta: ...
}
```

Both actions describe the same change in state. This is why, when you resolve with `null` or `undefined`, the payload property is not included. It would be redundant to include it.
