I want to implement voip feature in my app and want to send username as data in the voip push. What is the json formate for Voip push.?
Json payload for voip push
The format for a VOIP push notification is the same as it is for any other push notification. You'll probably want to add the username as a "custom property." Please see the APNs docs, especially the "Payload Key Reference" section, for details.
