Android Question Firebase how to insert time_to_live and delivery_receipt_requested

[tigrot]

Hi everybody,
I'm using Firebase with happy results. I'd like to put a cherry on my APP and set time_to_live and delivery_receipt_requested in my request, the first is to terminate delivery action after a time and the second is to get a receipt.
Anybody succeded in that?

The list of parameters is available here: https://firebase.google.com/docs/cloud-messaging/http-server-ref#downstream-http-messages-json

You need to add the keys and values to the 'm' map if you are using the B4J code to send messages.

Hi Erel, the issue is that time_to_live works fine while delivery_receipt_requested is not recognised by Firebase server

Private Sub SendMessageToSingleDevice(Devtoken As String, datastring As String)

    Dim Job As HttpJob
    Job.Initialize("SendMessage", Me)

    Dim m As Map = CreateMap("to": $"${Devtoken}"$)
    Dim noti As Map = CreateMap("body":"Notification ", "title":"New message!")
    Dim data As Map = CreateMap("data": datastring, "key": tokenstore, "tel": Starter.telefono)
    m.Put("notification", noti)
    m.Put("data", data)
    m.Put("content_available": True)
    m.Put("delivery_receipt_requested":True)
    m.Put("time_to_live":600)
    Dim jg As JSONGenerator
    jg.Initialize(m)
    Job.Tag=jg
    Log(jg.ToString)
    Job.PostString("https://fcm.googleapis.com/fcm/send", jg.ToString)
    Job.GetRequest.SetContentType("application/json;charset=UTF-8")
    Job.GetRequest.SetHeader("Authorization", "key=" & api_key)

End Sub

the log shows:

Red is the JSON sent, while green message and answer below is the answer from the engine.

It is not listed in the supported keys. It will not work.

You can send a FB message back as a "received ok".
