I'm having trouble getting payload attributes to display in the message body in MobilePush. I've tried using the CustomKeys and CustomPayload fields in the request, neither worked. Is the message body not able to access these fields using the standard %%Attribute%% format? This is very easy on the triggered email side, but the same approach doesn't seem to be working for mobile push.
The business example we're solving for here is the ability to send push notifications such as 'Thanks, we got order XXXXX, please click this link to see your order: XXXX'. How do I push the dynamic attributes into the message body without requiring that the message be fully constructed within the request? (doing it that way would require a code change to our calling application for simple changes to these push notifications).
