 #### Modifying the access token payload
 Similar to Setting additional token headers, some services, such as the Smartsheet API, require you to [add a hash to the access token request payloads](http://smartsheet-platform.github.io/api-docs/?javascript#oauth-flow). The `setTokenPayloadHandler` method allows you to pass in a function to modify the payload of an access token request before the request is sent to the token endpoint:
 
 
-    // Set the handler for adding Smartsheet's required SHA hash parameter to the payload:
-    .setTokenPayloadHandler(smartsheetTokenHandler)
-    ...
-    function smartsheetTokenHandler(payload) {
-        var codeOrRefreshToken = payload.code ? payload.code : payload.refresh_token;
-        var input = SMARTSHEET_CLIENT_SECRET + "|" + codeOrRefreshToken;
-        var hash = Utilities.computeDigest(Utilities.DigestAlgorithm.SHA_256,
-                                                input,
-                                                Utilities.Charset.UTF_8);
-        hash = hash.map(function(val) {
-            // Google appears to treat these as signed bytes, but we need them unsigned...
-            if (val < 0)
-            val += 256;
-            var str = val.toString(16);
-            // pad to two hex digits:
-            if (str.length == 1)
-            str = '0' + str;
-            return str;
-        });
-        payload.hash = hash.join("");
-        // Smartsheet doesn't need the client secret sent (secret is verified by the hash)
-        if (payload.client_secret) {
-            delete payload.client_secret;
-        }
-        return payload;  
-    }
+    // Set the handler for modifying the access token request payload:
+    .setTokenPayloadHandler(myTokenHandler)
