# Connecting SDK to API

To connect SDK to Oz API, specify the API URL and [access token](https://doc.ozforensics.com/oz-knowledge/guides/developer-guide/api/oz-api/use-cases/authentication) as shown below.

```swift
OZSDK.setApiConnection(Connection.fromServiceToken(host: "https://sandbox.ohio.ozforensics.com", token: token)) { (token, error) in
}
```

{% hint style="info" %}
Please note: in your host application, it is recommended that you set the API address on the screen that precedes the liveness check. Setting the API URL initiates a service call to the API, which may cause excessive server load when being done at the application initialization or startup.
{% endhint %}

Alternatively, you can use the login and password provided by your Oz Forensics account manager:

```swift
OZSDK.setApiConnection(Connection.fromCredentials(host: “https://sandbox.ohio.ozforensics.com”, login: login, password: p)) { (token, error) in
    // Your code to handle error or token
}
```

By default, logs are saved along with the analyses' data. If you need to keep the logs distinct from the analysis data, set up the separate connection for [telemetry](https://doc.ozforensics.com/oz-knowledge/other/faq#what-is-telemetry-and-why-should-i-use-it) as shown below:

```swift
let eventsConnection = Connection.fromCredentials(host: https://echo.cdn.ozforensics.com/,
                                login: <your_telemetry_user_eg_tm@company.com>,
                                password: your_telemetry_password)
OZSDK.setEventsConnection(eventsConnection) { (token, error) in
}
```
