+problem.

+```json
+{
+  "issue": "Card declined: insufficient funds"

+**Response (200)**:
+```json
+{
+  "acknowledged": true,

+**Error Responses**:
+- `404`: User profile not found

+#### User-Event Notifications
+
+DocuElevate sends admin push notifications (via Apprise) and fires outbound webhooks for three
+user-lifecycle events:
+
+| Event | Trigger | Notification type |
+|-------|---------|-------------------|
+| **New signup** | A first-time user logs in and a UserProfile is created | `NOTIFY_ON_USER_SIGNUP` |
+| **Plan change** | A user selects a new subscription tier during onboarding, or an admin changes their tier | `NOTIFY_ON_PLAN_CHANGE` |
+| **Payment issue** | An admin POSTs to `/api/admin/users/{user_id}/payment-issue` | `NOTIFY_ON_PAYMENT_ISSUE` |
+
+In addition to the Apprise push notification, each event also fires the matching webhook event
+(`user.signup`, `user.plan_changed`, `user.payment_issue`) to all active webhook configurations
+subscribed to that event, enabling integration with CRM, helpdesk (Jira, Zendesk, etc.), or
+payment processors.
