## Licensing

### License Types

There are two types of licenses available for **io.Manager** - a trial license and a paid license:

| License Type | Purpose | Behavior at Expiration |
|--------------|---------|------------------------|
| Paid | For development, staging, UAT, and production environment usage. | After the license expires, **io.Manager** will start logging warning messages, but will continue operating normally. |
| Trial | For PoC usage. | After the license expires, **io.Manager** will stop operating completely. |

### Applying the License Key

The license key can be passed to **io.Manager** via the `licenseKey` property of the configuration object for initializing **io.Manager**, or via the `API_LICENSE_KEY` environment variable, depending on your [deployment](https://docs.interop.io/manager/deployment/index.md) approach.

The following example demonstrates passing the license key when initializing **io.Manager**:

```javascript
import { start } from "@interopio/manager";

const config = {
    licenseKey: "my-license-key"
};

const server = await start(config);
```

The following example demonstrates passing the license key using an environment variable:

```cmd
API_LICENSE_KEY=my-license-key
```
