 ##### Server-side Rewarded Ad Unit Configuration

+Publishers can also supply the same impression-level configuration from the app with the ad unit's `setImpORTBConfig()` method. This is useful when a bidder does not return `rwdd` and the app needs to replace the default 120-second end-card completion time. Pass the `ext.prebid.passthrough` portion of the impression, for example:
+
+```json
+{
+  "ext": {
+    "prebid": {
+      "passthrough": [
+        {
+          "type": "prebidmobilesdk",
+          "rwdd": {
+            "completion": {
+              "video": {
+                "endcard": {
+                  "time": 15
+                }
+              }
+            },
+            "close": {
+              "postrewardtime": 0,
+              "action": "closebutton"
+            }
+          }
+        }
+      ]
+    }
+  }
+}
+```
 
+Serialize this object as JSON and pass it to `RewardedAdUnit.setImpORTBConfig()`. Prebid Server returns the passthrough data with the bid, where the SDK reads the `rwdd` configuration.
