Format of Callback subscriptions

[sgarg7]

Hi,

I've been trying to get Http callbacks to work with notifications. When I use a URL (eg http://requestbin.company.com) in the "subscriptions" field", I see the following error in the logs - notification send response: HTTP/1.1 500 illegal subscription format: Unrecognized token 'requestbin': was expecting ('true', 'false' or 'null')
When I try JSON matching the Request class in CallbackService.java, it gets read as two subscriptions split by the comma in the JSON. Is there a correct format that will work for the subscriptions field for callback?

Thank you

I too am running into an error posting Alert data. Is there a specific input required here?
TIA.

This is the templating engine used:

Here's the PR for this feature. There's some info in there as well:
#358

Let us know if it works out. We have not enabled this feature in our production environment and would like to get some feedback on it.

I started with the following in the "Subscriptions" field, following the format specified in the PR
{"uri": "http://requestbin.commpany.com/abcdefg", "method": "POST", "header": {}, "body": "Hello world", "template": null }

But upon saving and refresh, it changed to :
"body": "Hello world", "template": null }, "method": "POST", "header": {}, {"uri": "http://requestbin.commpany.com/abcdefg"

The JSON is being split based on the commas. So it looks like the subscription field is not the right place for the callback JSON. I added it to the "Custom Text" field of a notification. Will report back what I find.
