  You can associate entities on update using the same message described in [Basic update](update-delete-entities-using-web-api.md#bkmk_update) but you must use the @odata.bind annotation to set the value of a single-valued navigation property. The following example changes the account associated to an opportunity using the `customerid_account` single-valued navigation property.

+### Disassociate entities on update
+
+You can remove a reference to a single-valued navigation property when updating by setting the value to `null`. This method allows you to disassociate multiple references in a single operation.
+There are two ways to do this:
+
+You can set the value to `null` using the `@odata.bind` annotation:
+
+```http  
+PATCH [Organization URI]/api/data/v9.0/accounts(00000000-0000-0000-0000-000000000001) HTTP/1.1  
+Accept: application/json

+OData-Version: 4.0
+
+{
+	"[email protected]":  null,
+	"[email protected]": null
+}
+
+
+```  
+  
+ Or, just use the name of the single-valued navigation property. 
+  
+```http 
+PATCH [Organization URI]/api/data/v9.0/accounts(00000000-0000-0000-0000-000000000001) HTTP/1.1
