 Let's say for example we have an endpoint that mutates an issue:
 
 ```
-POST /api/0/organizations/{org}/issues/{issue}/
+PUT /api/0/organizations/{org}/issues/{issue}/
 ```
 
 When designing a batch interface, we simply expose it on the collection instead of the individual resource:
 
 ```
-POST /api/0/organizations/{org}/issues/
+PUT /api/0/organizations/{org}/issues/
 ```
 
 You may also need to expose selectors on batch resources, which can be done through normal request parameters:
 
 ```
-POST /api/0/organizations/{org}/issues/
+PUT /api/0/organizations/{org}/issues/
 {
   "issues": [1, 2, 3]
 }
