# API Key Authentication
API key authentication is the default method for invoking yCrash REST APIs. You pass your API key as a query parameter in the request URL. This approach is simple, stateless, and well suited for automation scripts, CI/CD pipelines, and integrations.
# How it works
Include the apiKey parameter in the URL of every API request. The server validates the key and processes the request if it is valid.
URL format:
https://<your-ycrash-server>/<api-endpoint>?apiKey=<YOUR_API_KEY>
1
For APIs that accept additional parameters, append them to the URL:
https://<your-ycrash-server>/<api-endpoint>?apiKey=<YOUR_API_KEY>&<param1>=<value1>&<param2>=<value2>

# Finding your API key
Your API key is provided with your yCrash license at the time of registration. You can also find it in the yCrash dashboard:
- Go to the yCrash home page.
- Locate the tool widget (GCeasy, HeapHero, FastThread).
- Click Launch REST API.
- The API endpoint shown in the popup includes your API key.
For more details, see How to find your API key in yCrash (opens new window).

# Tips
- Compression: For large files, you can compress the payload and pass the compression format in the
Content-Encodingheader (e.g.zip,gz). See the individual API documentation for details.
