+{
+  "viewerId": "alfie-lambert",
+  "linkedInReady": true,
+  "salesNavigatorReady": false,
+  "warmup": {
+    "status": "warming",
+    "details": {
+      "active_days": 2,
+      "daily_limit": 100,
+      "hourly_limit": 40,
+      "max_daily_limit": 500,
+      "max_hourly_limit": 100
+    }
+  }
+}
+```
+
+The `warmup` object is only present when the account warmup feature is enabled for the account. When warmup is complete the `status` field becomes `"completed"` and the `active_days` and limits reflect the final tier.
