# Release Version

You can capture the release version of your application using the **zipy.init()** method with options.

Initialise Zipy with your Project SDK key and begin recording the session replay. The release version will be captured as part of this.<br>

**zipy.init(**&#x59;OUR\_PROJECT\_SDK\_KE&#x59;**,** option&#x73;**)**<br>

Following are the Method Parameters:

| **Name** | **Description**                                                                                 |
| -------- | ----------------------------------------------------------------------------------------------- |
| sdk\_key | Your project SDK key                                                                            |
| options  | A JSON object which specifies optional parameters to initialize your recording with. (Optional) |

The option to be used with this method is described below:

* **releaseVer** - String&#x20;

This specifies a release version for your project making it easier for you to identify which release version of your project was used when your session was recorded or your error was captured.&#x20;

Example Usage:&#x20;

```generic
zipy.init("YOUR_PROJECT_SDK_KEY", {
   releaseVer: "0.1.0"
});
```
