Is it possible to process JSON and accessing parameters using service bus? - azure-logic-apps

Question

I have seen that it is possible to add a JSON schema when you are using the "HTTP Request"-trigger and adding the JSON schema in the "Request Body JSON Schema"-box.
I have also looked at adding schema in the "Integration Account", however the section in the documentation says its "to confirm that XML documents you receive are valid", which is not what i am looking for.
I am using a Azure Service Bus Queue.
In this case i am having PeekLock as a trigger, the idea is that the input in the service bus will be of a certain format. It will all be in JSON. I dont "care" or need to know what happens before the service bus, all i know is that each message will contain the same format. What my logic app is supposed to do is to receive the message in the service bus and then mail it to whoever its supposed to go to, and add if there is anything to add from blob storage. I want to be able to access certain "tags" or "parameters", since Service Bus only have its own few tags.
I used the jsonschema.net to get the schema, and here is the JSON of how a format will look like:
{
"items": [
{
"Key": "XXXXXX-XXXX-XXXX-XXXX-XXXXXXX",
"type": "Email",
"data": {
"subject": "Who is the father?",
"bodyBlobUID": "00000000-0000-0000-0000-000000000000",
"to": [
"darth.vader#hotmail.com"
],
"cc": [
"luke.skywalker#nomail.com"
],
"bcc": [
"leia.skywalker#nomail.com"
],
"encoding": "System.Text.UTF8Encoding",
"isBodyHtml": false,
"organisationUID": "00000000-0000-0000-0000-000000000000",
"BlobUIDs": [
"luke.skywalker#nomail.com"
]
}
}
]
}
So my questions are of 2 parts:
1: Is it possible to add JSON schemas without using the HTTP Request
trigger for using service bus?
2: If #1 is possible, or maybe it can
be done in another way. How do i access the tags or parameters of the
JSON format? At this moment i am trying to do transformations using
schemas and maps with the Integration account but it seems
unnecessary.

UPDATE: Parse JSON is now available in Logic Apps.
we will be releasing an action called JSON Parse next week, in which you can specify the service bus output as payload, define schema of the payload, then custom friendly tokens in subsequent steps.
