I just have a quick question on the payload for Push notification.
I see that Whatsapp probably exceed the normal GCM or APNs server payload of 4kb and 2kb. As it can send Images over Push notification. I am just wondering if i want to have push notification that has a payload that exceed the max payload, does it mean writing a custom push notification service with CCS XMPP connection? that is show in the list below? Or would it be something totally different? I am just wondering. I am just trying to find a direction to learn here, to see how Whatsapp does it, that they can do such quick and large payload push notification.
Thanks for your time!
