# Sink Pin
The **`Sink`** pin is a unique tool for creating an endpoint for the nodegraph. When you create a **`Sink`** node, you essentially generate the node that initiates the execution of the entire nodegraph.
The **`Sink`** node acts as the terminal point of your nodegraph, where the final processed output is directed.
In cases where you lack an AJA card and, consequently, can't create **`AJAIn`** and **`AJAOut`** nodes for video I/O connections, the **`Sink`** Node becomes a handy tool.
Without direct hardware connections, the **`Sink`** node allows you to process and manipulate data within the Reality Hub environment.
### Creating Sink Node
* Hover over the output pin of your desired node.
Creating Sink Node
