Welcome to the forums @sunnoy

Sorry, but I don't recommend you hi-jack core node internals.

The endpoint inject/{id} is only for the inject node - so if the fundamentals change with it -your node will break.

Instead, create your own endpoint, and handle it internally in your own node

Marcus will develop the answer for you, here is the missing code:

Use the above as an example (inject node internals)....

BUT for the love of god - dont use /inject - use something unique to your node.
anyone installing your Node will be very unhappy, if you break core nodes

The reason you are not getting data - is that you are trying to hijack the inject node - and it some has checks in place (I believe)

Develop your own, and you should get further

tks i have done this

But how do I find the relevant API references, for example RED.httpAdmin.post in the documentation Node-RED not in detail

Perhaps you are going off-piste somewhat?

Please back up for a second and describe what you are trying to do with your node so that we can help you understand the best way to approach things.
