Testing JSON Container Input queries

Hi,

I am fairly new to knime so please bear with me. I want to create a workflow that will ultimately lie on server but I can not access the server myself.

This workflow is supposed to receive a put request with a json body, that should be added to a sql databese. How can I test the node without entering the json manually? Is there a way to write these requests with thunder client or postman without the workflow being on a server? Alternatively, is there a way to simulate these requests with a node?

My company is using knime 4.6 in case that matters.

Thank you for any suggestions :slight_smile:
