Update a flow using http request

However, I cannot see where to put the JSON data on my http request node.

Hello ..

The http-request node has an input that can accept a msg.
The body of the request is sent using msg.payload
( You could use a preceding Inject, Change, Function or any other node to construct a msg.payload. )

If you select the http-request node and view its Help tab on the side window
you get a detailed explanation of all the properties that you can set for that node.
