I am new to NodeRED and I'm testing out the APIs. I am trying to Post/trigger a flow on nodeRED through postman. According to the api documentation, something like this should work: curl --location --request POST 'http://localhost:1880/flows' \ --header 'Content-Type: application/json' \ --header …

Hi @Ihum You mixing together two different actions. The requests to /flows or /flow are used to change what flows are currently deployed in the runtime. The payload format used by /flow is different to /flows - which is why you are getting an error. The docs cover the details of the required forma…

[image] Ihum: The flows on the server have been updated. That means you have to do a deploy. So do the deploy and try again. Also, you need to seperate the 'curl' statement from the flow in your post or it will not import the flow you provided only has an inject and debug node. when postin…

Doesn't the POST to /flow do a deploy? If so then should @Ihum just refresh the browser rather than deploy? The 204 no content message, however, suggests that the POST is not correctly formatted.

[image] Colin: Doesn't the POST to /flow do a deploy? Ahh, I didn't notice that when the curl and flow were all as one before I edited the post. Should have reread it with fresh eyes :roll_eyes:

I have edited my flow in original question to a basic flow that prints the date. And on Postman I am posting to http://localhost:1880/flow. But I am getting the error: { "code": "unexpected_error", "message": "missing nodes property" } What does that mean? What do you mean by the post not …

Thank you. I have edited the flow to include inject, debug and a function. I have also changed it to [POST/flow](https://nodered.org/docs/api/admin/methods/post/flow), but I am getting the error: { "code": "unexpected_error", "message": "missing nodes property" }

Quick question: If I don't already have the flow deployed in the runtime and I want to be able to deploy and trigger at the same time using Postman, would a HTTP In node handle both the deployment and the triggering?

[image] Ihum: would a HTTP In node handle both the deployment and the triggering? No, they are completely separate actions. If you want to trigger a flow whenever it gets deployed, then you should follow the advise @E1cid gave you earlier today - Trigger NodeRed flow from postman - #4 by E1c…

Also if you want the flow to trigger after deploy, the you would need to set the inject to trigger once after 0.1 seconds
