# Keys

In the **Keys** section under **Settings**, you can easily view or copy your API key, view session starts by the last seven days, and app version sessions from the last seven days.

API Key [#api-key]

You'll use your API key to initialize the Superwall client in your apps. Each one is prepended with `pk_` and then the identifier. To easily copy it, **click** the **Copy** icon on the right-hand side:

> **Note**

These are public SDK keys used to configure Superwall in your app. For scoped organization API keys used by servers, CI jobs, or other backend automation, use [Access Controls](/docs/dashboard/dashboard-settings/overview-settings-access-controls).



Session starts by SDK version [#session-starts-by-sdk-version]

Use the session starts by SDK chart to see how many sessions are being started, split out by the SDK version of Superwall.

This helps debug any potential issues that may occur by comparing sessions against the version of our SDK users are on. Of course, if your issue appears to be related to Superwall's SDK — always feel free to reach out so we can investigate.

App version [#app-version]

Similarly, the app version chart helps you narrow down issues by showing sessions split out by app versions. If the use of our SDK didn't change, but your app version did, and an issue is occurring — then it may related to your app specific logic.
