Hi @biswajitjei02n8v0iw, If you set the listener key to a " **/**" then it will listen for every change across your entire database. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/b/0b8708f4f0bbb5ed35d925013c61a72724dfddf1.png) Note here that both DataChanged blocks on the right will create the same outcome. If you want to target a specific object then change the **Realtime\_DB1 Get** key to your specified location. ---
