Use `POST /api/v1/tickets/{internal_ticket_id}/add_line_item` to add line items to tickets. Both `name` and `description` fields are required (422 if either missing). Never use timers.

**Why:** `/line_item`, `/line_items`, and PUT `line_items_attributes` all 404. The correct endpoint was found via Syncro Swagger spec at api-docs.syncromsp.com. Mike has explicitly said never use timers.

**How to apply:**
- Path uses internal ticket ID (e.g., 111387456), not ticket number (32339)
- Required fields: `name`, `description`, `quantity`, `price`, `taxable` (and `product_id` if catalog item)
- Response is a flat object — parse `.id` directly (not `.line_item.id`)
- For testing/practice, use internal ACG account only (customer ID 15353550)

Example:
```
POST /api/v1/tickets/111387456/add_line_item
{"product_id":1049360,"name":"Labor- Warranty work","description":"...","quantity":1,"price":0.0,"taxable":false}
```
