# Token Validation

The Lean.x API employs API keys for secure request authentication. Easily handle and oversee your API keys using the Lean.x Dashboard.

Ensuring the security of your API keys is crucial due to the substantial privileges they carry. Avoid sharing confidential API keys in public platforms like GitHub or client-side code.

For the protection of your data, it is mandatory to transmit all API requests via HTTPS. Attempts to initiate API requests using plain HTTP will not yield success. Furthermore, API requests lacking proper authentication will not undergo processing.

The token in the following example is derived from the sample token provided on the  [Credential](/api-docs/credential.md) page. As recommended, kindly obtain your own test credentials from the Sandbox Dashboard.
{% endhint %}
