Container Input (JSON) - receiving data without parameter name

I would like to create a workflow which would work as a webhook.
Sender is sending only json in the body of request:
However Container Input (JSON) node requires a parameter name (by default it is json-input), which makes expected body format like this:
{“json-input” : {“data”:“data”}}
Is it possible to receive json without any parameter name or make this work if the sender is not able to modify json format?

Instead of using the Container Input (JSON) node, how about just using the JSON Reader node? You can give it the URL directly, and no parameter is required.

Or maybe I’m misunderstanding your question somehow?

No, it is not possible to receive json without any parameter name. The parameter names are necessary for assigning the input to a node.

Sorry for the delayed answer!
