I am having trouble sending a topic downstream message using Firebase. Everything works fine when I send to single or multiples users using tokens, my code looks like this
notif = {
'to': 'TOKEN',
'data': {'msg': 'whatever'},
}
opener = urllib2.build_opener()
data = json.dumps(notif)
req = urllib2.Request(
FCM_URL,
data=data,
headers={
'Content-Type': 'application/json',
'Authorization': 'key=' + API_KEY,
}
)
response = opener.open(req)
However if I replace the recipients using a topic, more precisely the code becomes
notif = {
'to': '/topic/MY_TOPIC',
'data': {'msg': 'whatever'},
}
opener = urllib2.build_opener()
data = json.dumps(notif)
req = urllib2.Request(
FCM_URL,
data=data,
headers={
'Content-Type': 'application/json',
'Authorization': 'key=' + API_KEY,
}
)
response = opener.open(req)
{"multicast_id":id,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}
Is there something I am missing? I should outline that sending topic messages from the firebase console works fine.
Any help more than welcome, Best & thanks! Alex
Ah so silly...
I was missing s in topics, the correct form is hence
notif = {
'to': '/topics/MY_TOPIC',
'data': {'msg': 'whatever'},
}
Hope it helps someone anyway!
Best, A
