> - 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.

# Stripe

> Attribute Stripe payments and subscriptions back to the install and ad campaign that drove them.

With the Stripe integration, you can:

1. Attribute web purchases and subscriptions collected through Stripe back to the install and ad campaign that drove them.
2. See Stripe revenue alongside your app-store revenue in Appstack.

<Note>
  **To successfully connect Stripe, you must:**

  1. Have Stripe enabled for your organization (currently in pilot). If you see **Coming soon**, contact [support@appstack.tech](mailto:support@appstack.tech).
  2. Have editor access to the project, and no pre-launch apps in it.
  3. Have the Appstack SDK integrated, and a server that creates your Stripe Checkout Sessions.
</Note>

## Connect to Stripe

<Steps>
  <Step title="Install the Appstack app in Stripe">
    In Appstack, go to **Integrations** > **Stripe** and click **Continue**. Install the Appstack app in Stripe, then click **Continue setup** to return to Appstack.
  </Step>

  <Step title="Choose the account and products">
    Select the Stripe account for this project and at least one product. A single connection covers both your iOS and Android apps.

    <Note>
      * Each project uses one Stripe account, and the account can't be replaced yet.
      * An organization can register several Stripe accounts, and one account can serve several projects in that organization.
      * A Stripe account belongs to one Appstack organization only.
      * Each product maps to one project. Use **Add products** on the integration page to add more later; at least one must stay mapped.
    </Note>
  </Step>

  <Step title="Send the metadata with every purchase">
    Read the Appstack ID in your app and send it to your server, together with the app's `app_id`, in the request that creates the checkout:

    | Key | Value |
    | :- | :- |
    | `app_id` | iOS: the numeric App Store ID. Android: the package name. |
    | `appstack_id` | The Appstack ID returned by the SDK. |

    <Warning>
      Always send the `app_id` of the app where the purchase started. If your project has both an iOS and an Android app and you always send the same `app_id`, every subscription and purchase is attributed to that one app. Set `app_id` per platform, never as a single hardcoded value on your server.
    </Warning>

    <CodeGroup>
      ```swift Swift theme={null}
      let appstackId = AppstackAttributionSdk.shared.getAppstackId()
      ```

      ```kotlin Kotlin theme={null}
      val appstackId = AppstackAttributionSdk.getAppstackId()
      ```

      ```typescript React Native theme={null}
      const appstackId = await AppstackSDK.getAppstackId();
      ```

      ```dart Flutter theme={null}
      final appstackId = await AppstackPlugin.getAppstackId();
      ```

      ```csharp Unity theme={null}
      using Appstack;

      string appstackId = AppstackSDK.GetAppstackId();
      ```
    </CodeGroup>

    Then add both keys when you create the Checkout Session.

    **Subscriptions**: use `subscription_data.metadata`.

    <CodeGroup>
      ```bash curl theme={null}
      curl https://api.stripe.com/v1/checkout/sessions \
        -u "sk_live_...:" \
        -d mode=subscription \
        -d "line_items[0][price]={{PRICE_ID}}" \
        -d "line_items[0][quantity]=1" \
        -d "success_url=https://example.com/success" \
        -d "subscription_data[metadata][app_id]={{APP_ID}}" \
        -d "subscription_data[metadata][appstack_id]={{APPSTACK_ID}}"
      ```

      ```javascript Node.js theme={null}
      const session = await stripe.checkout.sessions.create({
        mode: "subscription",
        line_items: [{ price: priceId, quantity: 1 }],
        success_url: "https://example.com/success",
        subscription_data: {
          metadata: { app_id: appId, appstack_id: appstackId },
        },
      });
      ```

      ```python Python theme={null}
      session = stripe.checkout.Session.create(
          mode="subscription",
          line_items=[{"price": price_id, "quantity": 1}],
          success_url="https://example.com/success",
          subscription_data={"metadata": {"app_id": app_id, "appstack_id": appstack_id}},
      )
      ```
    </CodeGroup>

    **One-time payments**: use `payment_intent_data.metadata`.

    <CodeGroup>
      ```bash curl theme={null}
      curl https://api.stripe.com/v1/checkout/sessions \
        -u "sk_live_...:" \
        -d mode=payment \
        -d "line_items[0][price]={{PRICE_ID}}" \
        -d "line_items[0][quantity]=1" \
        -d "success_url=https://example.com/success" \
        -d "payment_intent_data[metadata][app_id]={{APP_ID}}" \
        -d "payment_intent_data[metadata][appstack_id]={{APPSTACK_ID}}"
      ```

      ```javascript Node.js theme={null}
      const session = await stripe.checkout.sessions.create({
        mode: "payment",
        line_items: [{ price: priceId, quantity: 1 }],
        success_url: "https://example.com/success",
        payment_intent_data: {
          metadata: { app_id: appId, appstack_id: appstackId },
        },
      });
      ```

      ```python Python theme={null}
      session = stripe.checkout.Session.create(
          mode="payment",
          line_items=[{"price": price_id, "quantity": 1}],
          success_url="https://example.com/success",
          payment_intent_data={"metadata": {"app_id": app_id, "appstack_id": appstack_id}},
      )
      ```
    </CodeGroup>

    <Warning>
      The Checkout Session's top-level `metadata`, and metadata on the Customer or Product, is not enough. Use the nested parameters above.
    </Warning>

    <Note>
      **Payment Links**: a static Payment Link can't carry a different `appstack_id` per install, and Appstack doesn't read `client_reference_id`. Create Checkout Sessions from your server instead.
    </Note>
  </Step>
</Steps>

<Warning>
  The integration activates once at least 50% of new live-mode subscriptions over the last 24 hours include a valid `app_id` and `appstack_id`. One-time payments alone don't activate the integration yet.
</Warning>

## List of events

| Name | Definition |
| :- | :- |
| `st_trial_started` | Free trial begins. |
| `st_subscription_started` | Paid subscription starts, with no trial. |
| `st_trial_converted` | Trial becomes paid. |
| `st_subscription_renewed` | Subscription renews. |
| `st_in_app_purchase` | One-time purchase. |

## Troubleshooting

| Problem | Solution |
| :- | :- |
| Status stays on **Waiting for events** | Check that new live-mode subscriptions for the selected products include both keys in `subscription_data.metadata`. |
| Alert about `app_id` | Send the App Store ID (iOS) or package name (Android) of an app in this project, not the bundle ID. |
| Alert about `appstack_id` | Make sure the app reads the Appstack ID with the SDK and your server forwards it on every checkout. |
| Events coverage stays low after a fix | Older subscriptions keep their original metadata. Fixes only apply to new purchases. |

To disconnect, click **Disconnect** on the Stripe integration page. This removes the project's connection and product mappings; the Stripe account stays registered to your organization.
