# SDK Integration

In addition to our API, the Gigastore SDK allows your customers to install the eSIM with a tap of a button in your mobile app instead of scanning QR codes or entering activation codes in your device's settings. The SDK can also check the user device's eSIM capability. We recommend setting up the API integration first.

### Get Started <a href="#overview" id="overview"></a>

You need a [Gigastore](https://dent.giga.store) account to use the [SDKs](https://dent.giga.store/#/sdk/ios-sdk) or [webhooks](/webhooks/first-steps.md) documented on this site.

### Credentials

Integrate the iOS SDK or Android SDK into your mobile apps and use the SDK key and webhooks provided by [Gigastore.](https://dent.giga.store/#/sdk/ios-sdk)

### Integration Flow <a href="#overview" id="overview"></a>

Before deep-diving into detailed specifications, look at the visual overview of the process for installing and activating eSIM.
