Comparing what you wrote with Ionic Docs - Ionic Documentation this all looks good. I think the request is well formed and you are using the correct uuid.
Tried without that?
deploy of the channel is the currently active deploy, right?

Hi,
I wish I could be of more help here, but at our current price point our team doesn’t have the resources to support this kind of direct debugging of individual instances of our services. Instead, we work to keep our technical documentation up to date and comprehensive so that our community of developers have the resources they need to help themselves and help each other. I recommend you check out the following resources:
The Ionic Forum (extremely active Q&A forum, this is a great place to ask questions!):
Yeah, I assume you still need the Auth stuff for that to work. That is the call you made with ?channel=, now just testing if without it maybe returns everything or useful data to create the correct request you were trying.
