Adding options like dry_run and collapse key to GCM notification

[callmeahab]

Can't find a way to send options parameters from https://developers.google.com/cloud-messaging/http-server-ref#downstream-http-messages-json to gcm. Tried adding to notification and data but they don't work there. Also tried adding them to notification payload directly but am getting key does not exist error.

Am I missing something here?

Thanks

When you add to the payload directly, are you using string keys or atom keys?

It seems to work if i use atom keys. Like so:

payload = Map.put(n.payload, :dry_run, true)
notification = Map.put(n, :payload, payload)

However I'm not sure since for gcm response i always get just :ok atom, and not the response described in the documentation.

Also probably unrelated, but data object, or stuff like icons i send to android doesn't show up if app is not in the foreground. But that could be bug on the android side.

As of v1.2.1 the following keys are now top-level on the FCM struct:

• time_to_live
• collapse_key
• restricted_package_name
• dry_run

Closing this.
