Thanks to [this post](https://discourse.nodered.org/t/automate-updating-nodes-to-the-flow-library/46869/6)  
I have update the script to xonsh script

```xonsh
import re
COOKIES_FILE="cookies.txt"
MODULE_NAME=$ARG1 #ex:@malysus/node-red-contrib-mqtt-auto

touch @(COOKIES_FILE)
rm @(COOKIES_FILE)

# get the _csrf token
cmd= f"".split(" ")
print(" ".join(cmd))
csfr=$(curl -s -c @(COOKIES_FILE) -b @(COOKIES_FILE) -XGET 'https://flows.nodered.org/add/node')

regex = r"_csrf\" type=\"hidden\" value=\"([^\"]+)\""
matches = list(re.finditer(regex, csfr, re.MULTILINE))
try:
    token=matches[0].group(1)
    print(f"_csrf token was found to be {token}")
    module=f"module={MODULE_NAME}&_csrf={token}"
    result=$(curl -s -XPOST "https://flows.nodered.org/add/node" -c @(COOKIES_FILE) -b @(COOKIES_FILE) -H "referer: https://flows.nodered.org/add/node" -H "Content-Type: application/x-www-form-urlencoded" -H "x-requested-with: XMLHttpRequest" -d @(module))
    print(result)
except Exception as e:
    print(e)

Here's the same as a Node-RED flow (using exec & curl):

```

The initial inject is given the module name and it should just work.

Also I changed the referer on the second request to be `https://flows.nodered.org/node/<module>` as that's what the browser was sending.

i try to make the equivalent for "[https://flows.nodered.org/flow/xxxxxx/refresh](https://flows.nodered.org/flow/xxxxxx/refresh)" have any idea how it's managed authentication?

I HAVE CREATED A [GIST](https://gist.github.com/malys/1c60cb72bcc2d05ed2703edda72d4971) with your code.

I should be easier to make change and share it.

No idea. It's non-trivial because of the login via github option. It would all be far simpler if there were to be an REST api that could be utilised to do all this.
