Hello everyone
I would like to send some values ​​in a JSON format, but I want to use variables as placeholders for these values. Does anyone have an idea how to do this?

Thanks for your time!

This is at the very core of node-red. I would suggest to go through the documentation and how to work with messages. To create a "template" for messages, you can use the template node as well.

In addition, you can use JSONata to also do this.
