+# Push Notification Test Payloads
+
+These `.apns` files can be dragged onto the iOS Simulator to test push notifications with action buttons.
+
+## How to Use
+
+1. Run the app on the iOS Simulator
+2. Drag and drop any `.apns` file onto the Simulator window
+3. The notification will appear with the appropriate action buttons
+
+## Before Testing
+
+Edit the `task_id` in each file to match a valid task ID from your database.
+
+## Available Payloads
+
+| File | Category | Actions | Description |
+|------|----------|---------|-------------|
+| `task_overdue.apns` | TASK_ACTIONABLE | edit, complete, cancel, mark_in_progress | Overdue task notification |
+| `task_due_soon.apns` | TASK_ACTIONABLE | edit, complete, cancel, mark_in_progress | Task due within threshold |
+| `task_in_progress.apns` | TASK_IN_PROGRESS | edit, complete, cancel | Task being worked on |
+| `task_cancelled.apns` | TASK_CANCELLED | uncancel, delete | Cancelled task |
+| `task_completed.apns` | TASK_COMPLETED | (none - read only) | Completed one-time task |
+| `task_assigned.apns` | TASK_ACTIONABLE | edit, complete, cancel, mark_in_progress | Task assigned to user |
+| `task_generic_free_user.apns` | TASK_NOTIFICATION_GENERIC | (none) | Free user sees generic message |
+
+## iOS Notification Categories
+
+The `category` field in `aps` maps to these iOS notification categories:
+
+- `TASK_ACTIONABLE` - For overdue, due_soon, upcoming tasks (full action set)
+- `TASK_IN_PROGRESS` - For tasks currently being worked on
+- `TASK_CANCELLED` - For cancelled tasks (can uncancel or delete)
+- `TASK_COMPLETED` - For completed one-time tasks (read-only, no actions)
+- `TASK_NOTIFICATION_GENERIC` - For free users (no actions, generic message)
+
+## Payload Structure
+
+```json
+{
+    "Simulator Target Bundle": "com.tt.casera.CaseraDev",

+## Custom Data Fields
+
+| Field | Type | Description |

+## Notes
+

+- `thread-id` groups related notifications together
+- The app must register notification categories on launch for actions to work
