问题
I've been implementing Notification Channels in my android app to support recent android versions.
You can set the notification channel id when sending messages from the firebase web console, but I was not able to find out how to set the channel id when sending messages via fcm rest api.
Notification channels are not mentioned in the reference (https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages), but I am pretty sure there must be a way to set the channel id.

The key name I was missing is android_channel_id
I found the key name in the Legacy HTTP Server Protocol docs (https://firebase.google.com/docs/cloud-messaging/http-server-ref)
