[SIP Beyond VoIP] push failed with code 400: Bad Request Invalid JSON payload received

[Tijmen de Mes]

Hi Vasilios,

If you use ‘linphone' as app_type, it will send out a JSON like in your pastebin. For the latest google messaging api this format is clearly not a supported format and it should look more like your test push notification.

The format for the linphone app_type is taken from their wiki and I guess can only be used with https://fcm.googleapis.com/fcm/send <https://fcm.googleapis.com/fcm/send>.

Is your client based on linphone?

If you just want to send a JSON like the one from your test push notification, you can fairly easy do this by adding a custom application. 

A skeleton app for this is already given in the config dir (myapp.py). If you just want use Firebase, you can need to customise the FirebasePayload and return a dict which contains the required structure. I made this gist for your app and can can further customise it if you want: 

https://gist.github.com/tijmenNL/73ca3c3bc8275540e8500b9e3ab35ebc <https://gist.github.com/tijmenNL/73ca3c3bc8275540e8500b9e3ab35ebc>

You can place this file in /etc/config/applications and change your config to have app_type = customapp

Hope this helps you.

Best regards,

Tijmen de Mes
