 Most of Marketing API can be found in SDK classes. If you don't find the one you want to access, it is possible to construct an Ad-hoc APIRequest:
 
 ```java
-    APIRequest<AdAccount> request = new APIRequest<AdAccount>(context, "me", "/adaccounts", "GET", AdAccount.getParser());
+    APIRequest<AdAccount> request = new APIRequest<AdAccount>(context, "me", "/adaccounts", HttpMethods.GET, AdAccount.getParser());
     APINodeList<AdAccount> accounts = (APINodeList<AdAccount>)(request.execute());
 ```
