# Integrate SDK

## Import <a href="#import" id="import"></a>

Import the `DENTGigastoreSDK` into your file.

```swift
import DENTGigastoreSDK
```

## Load <a href="#load" id="load"></a>

The `load` method initializes the Gigastore SDK. Please make sure to include your "SDK Key" here. You can find your SDK Key in the [Gigastore](https://dent.giga.store) under "SDK -> iOS -> Sales Channel".

```
let sdkKey = "SDK KEY"
​Gigastore.load(withSDKKey: sdkKey)
```

## Set UserToken​

Please use an identifier from your system. You can e.g. use a self-signed JSON Web Token (JWT) as the `userToken`. That way you are able to verify the requesting device on your server when receiving the activation request webhook from Gigastore.

```
let userToken = "USER_TOKEN_1234567"
​Gigastore.setUserToken(userToken: userToken)
```

{% hint style="info" %}
&#x20;This parameter will be provided in the [ActivationRequest Webhook](https://docs.giga.store/sdk-webhooks/activationrequest) to enable your server to check if the user is eligible to activate an eSIM. This parameter will **not be stored** on our servers.
