> - Appstack is invite-only. Request access at https://cal.com/appstack/appstack-demo.
> - Enhanced app campaigns (EAC) redirect users straight to the app store or a Custom Product Page. Appstack is not a web-funnel or landing-page product.
> - The Appstack SDK must be installed in the app to match installs and measure in-app events.
> - Appstack does not need or use SKAdNetwork. It can run alongside SKAdNetwork without conflict.
> - Appstack measures, attributes, and forwards signals. It is not a media-buying platform.

# Qonversion

> Wire Qonversion into the Appstack SDK to attribute subscriptions and revenue to the install and ad campaign that drove them.

Wire Qonversion into the Appstack SDK to attribute subscriptions and revenue to the install and ad campaign that drove them.

With the Qonversion integration, you can:

* Use Qonversion subscription events to run enhanced app campaigns.
* See trials, subscriptions, renewals and refunds next to the install and the campaign that drove them.

Custom user properties are supported by every Qonversion SDK. On iOS, `getAppstackId()` returns a stable ID even before the Appstack SDK is configured from version 4.3.1.

## Connect to Qonversion

<Steps>
  <Step title="SDK configuration">
    Set the Appstack ID as a Qonversion custom user property named `appstack_id`. Do it on every app start, right after Qonversion is configured, with the value from `getAppstackId()`. Appstack uses it to link each Qonversion event to the install, and the campaign, that produced it.

    <CodeGroup>
      ```swift Swift theme={null}
      // ...
      // Qonversion is initialized here
      // ...

      if let id = AppstackAttributionSdk.shared.getAppstackId() {
          Qonversion.shared().setCustomUserProperty("appstack_id", value: id)
      }
      ```

      ```kotlin Kotlin theme={null}
      // ...
      // Qonversion is initialized here
      // ...

      AppstackAttributionSdk.getAppstackId()?.let { id ->
          Qonversion.shared.setCustomUserProperty("appstack_id", id)
      }
      ```

      ```typescript React Native theme={null}
      // ...
      // Qonversion is initialized here
      // ...

      const id = await AppstackSDK.getAppstackId();
      if (id != null) {
        Qonversion.getSharedInstance().setCustomUserProperty('appstack_id', id);
      }
      ```

      ```dart Flutter theme={null}
      // ...
      // Qonversion is initialized here
      // ...

      final id = await AppstackPlugin.getAppstackId();
      if (id != null) {
        Qonversion.getSharedInstance().setCustomUserProperty('appstack_id', id);
      }
      ```

      ```csharp Unity theme={null}
      // ...
      // Qonversion is initialized here
      // ...

      var id = AppstackSDK.GetAppstackId();
      if (id != null)
      {
          Qonversion.GetSharedInstance().SetCustomUserProperty("appstack_id", id);
      }
      ```
    </CodeGroup>

    <Warning>
      The property key must be exactly `appstack_id`: any other key breaks attribution.
    </Warning>
  </Step>

  <Step title="Copy the credentials">
    In the Appstack console, open the Integrations page of your project and select Qonversion. In the Credentials section, copy the Webhook URL and the Authorization token.
  </Step>

  <Step title="Paste the credentials">
    In Qonversion, create a webhook. Paste the Webhook URL into the Webhook URL field and the Authorization token into the Header Authorization-Token Value field.

    <Warning>
      The integration shows an error if less than 50% of the events received over the last 24 hours include an Appstack ID.
    </Warning>
  </Step>
</Steps>

## Test with sandbox events

After the integration is connected, Qonversion sends sandbox events to Appstack automatically. You do not need any extra configuration. Sandbox events show only on the SDK page in the Development environment, so they never mix with your production data.

1. **Make a sandbox purchase.** Install a build of your app that includes the integration, then start a trial or make a purchase with a sandbox account, such as an App Store sandbox tester or a Google Play license tester.
2. **Open the Development environment.** In Appstack, select SDK from the side menu, make sure the correct application is selected, then select the Development environment.
3. **Check the event.** Find the Qonversion event in the list, for example `qo_trial_started`. This confirms that events reach Appstack. Open View parameters and confirm that the event contains the `appstack_id`.

## List of events

Below is a list of events you can forward to ad networks and analytics tools to optimize your campaigns.
