send notification fulfiller order by status shipping

[arturo82]

Hello, I try send a notification by status shipping. But is not working.

Example:
Status = "open",
ShipmentStatus = "ready_for_pickup",
LocationId = UsId.LocationId,
TrackingCompany = "DarkStore",
TrackingUrl = "https://dominio.com.mx/rastreo/" + intrastreo.ToString(),
TrackingNumber = intrastreo.ToString(),
NotifyCustomer = true,
OrderId = id

and

Status = "open",
ShipmentStatus = "in_transit",
LocationId = UsId.LocationId,
TrackingCompany = "DarkStore",
TrackingUrl = "https://dominio.com.mx/rastreo/" + intrastreo.ToString(),
TrackingNumber = intrastreo.ToString(),
NotifyCustomer = true,
OrderId = id

Some an idea?
