# OrderBy
### Order by Filter
A list of items can be returned in a specific order. To specify the ordering, provide a property to order by and whether the order is ascending or descending.
#### Example
**Order contacts by email address**
* **Ascending**
```
EmailAddress
```
becomes
```
https://api.xero.com/api.xro/2.0/Contacts?order=EmailAddress
```
in the query string.
* **Descending**
```
EmailAddress DESC
```
becomes
```
https://api.xero.com/api.xro/2.0/Contacts?order=EmailAddress%20DESC
```
in the query string.
