Why don't you just generate the URL in node-red and miss out the python part altogether?

Secondly, if you must call python, are you able to modify it to send the data in JSON format?

Lastly, if you have no other options, use regex to extract the URL from that string.

Ps, it's not 100% clear what is generating that string as you haven't attached a debug node to the python node - so some of what I've said is speculation.

Use a http request node.

The [cookbook](https://cookbook.nodered.org/http/) has lots of examples. Work through them and you get your data in no time

I have closed your second thread. Please don't start new topics on the same subject.

Change the debug node - set to show complete message.

Expand all properties. What do you see?

That doesn't look anything like the output of a http request node. Nor doe it look like you have set show full message.

Show a screenshot shot of your flow and the debug output from into and out of the http request.

@Steve-Mcl I think you've misinterpreted what you're being shown.

This is the message being received that contains the url to get. The question is how to do that.

@mykerinos1 You say you've tried with the HTTP Response node - that is not the right node to use. You should use the HTTP Request node. That node will make an http request to the url provided in `msg.url`. So you will need to add a Change node to **move** `msg.payload` to `msg.url`.

At the moment, the url you have is in `msg.payload`. You need it to be in `msg.url` before you pass it to the HTTP Request node.

Add a **Change** node before the HTTP Request node. Configure it to **move** `msg.payload` to `msg.url`.

Another one stumped by the change node.

A few threads I've seen lately lead me to think **Copy** might be more appropriate than **Set** (translates better (see the [German issue](https://discourse.nodered.org/t/restart-flow-after-changing-data/27104/25) where it reads as **Until** ),. I feel **Copy** is a bit clearer and as a bonus, the 2 fields would remain in the same place when you switch between **Move** and **Copy** mode)

_(Not the place to discuss this I know - but contextually related)_
