+/**
+ * Secret Store is an API that allows Stripe Apps developers to securely persist
+ * secrets for use by UI Extensions and app backends.
+ *
+ * The primary resource in Secret Store is a <code>secret</code>. Other apps can't
+ * view secrets created by an app. Additionally, secrets are scoped to provide
+ * further permission control.
+ *
+ * All Dashboard users and the app backend share <code>account</code> scoped
+ * secrets. Use the <code>account</code> scope for secrets that don't change
+ * per-user, like a third-party API key.
+ *
+ * A <code>user</code> scoped secret is accessible by the app backend and one
+ * specific Dashboard user. Use the <code>user</code> scope for per-user secrets
+ * like per-user OAuth tokens, where different users might have different
+ * permissions.
+ *
+ * Related guide: <a
+ * href="https://stripe.com/docs/stripe-apps/store-auth-data-custom-objects">Store
+ * data between page reloads</a>.
+ *
+ * @property string $id Unique identifier for the object.
+ * @property string $object String representing the object's type. Objects of the same type share the same value.
+ * @property int $created Time at which the object was created. Measured in seconds since the Unix epoch.
+ * @property bool $livemode Has the value <code>true</code> if the object exists in live mode or the value <code>false</code> if the object exists in test mode.
+ * @property string $name A name for the secret that's unique within the scope.
+ * @property null|string $payload The plaintext secret value to be stored.
+ * @property \Stripe\StripeObject $scope
