I'm newly log my datapoints with InfluxDB. I want to create a template to delete datapoints via the InfluxDB API. There is a curl command to delete datapoints, but I don't know how to run this command in Node-RED.
You can run the curl request in the http request node as a post request. Setting the headers in the request node, or passed to the request node in msg.headers. The data would be passed to the request node using msg.payload.
Have a go and if you run into trouble you can post here an export of the flow that is not working. How to import/export a flow
