i am trying to call the firebase cloud messages API like this:
fetch('https://fcm.googleapis.com/fcm/send',
{
method: 'POST',
headers: {
// 'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
'Content-Type': 'application/json',
'Authorization': 'key=AA##A8RX######Kt-SrCn##eXu'
},
body: {
"notification":{
"title":"note-Title",
"body":"note-Body"
},
"to":"??????"
}
})
Console output:
POST https://fcm.googleapis.com/fcm/send 400 ()
honestly i have no idea what i have to insert after “to”.
I want to send the push notification to all users.
Please help.
