I hope I posted this in the right place I need helping to output a string from python script into the curl function of webhook Note that I am new to python, never worked with json and in the process of configuring mattermost for the first time. I have the following python script ``` users=['mark','john','steve'] text='' for user in users: text+=str(user + " ") print(text) ``` how can I use text variable which is a string in the curl function in the text option or any way that what I need works `curl --insecure -i -X POST -H 'Content-Type: application/json' -d '{"text": 'HERE'}' https://10.10.10.6/hooks/84kk9emcdigz8xta1bykiymn5e` I tried that curl --insecure -i -X POST -H ‘Content-Type: application/json’ -d ‘{“text”: ‘python /home/scripts/python-script.py’}’ [https://10.10.10.6/hooks/84kk9emcdigz8xta1bykiymn5e](https://10.10.10.6/hooks/84kk9emcdigz8xta1bykiymn5e) and got that error `{"id":"Unable to parse incoming data","message":"Unable to parse incoming data","detailed_error":"","request_id":"fpnmfds8zifziyc85oe5eyf3pa","status_code":400}` Any help appreciated Thank you ---

Hi there, You’re definitely in the right place. 🙂 The best way to send requests from a Python script to Mattermost is to use one of the Python libraries available [like this one](https://github.com/Vaelor/python-mattermost-driver). That way you don’t have to worry about outputting the request in a way that `curl` can understand. Happy to help if you have any more questions! ---

Your script seems to be fine, the import error is a bit strange… Are you running windows? If yes, maybe (I don’t much windows experience though) python can’t find the modulepath. Can you run `pip3 install mattermostdriver` again and post the output? Are you installing it globally on the system, or in a python virtual environment (I would recommend that btw) ---

Are you using a ‘valid’ (meaning, it is trusted by your system) certificate for your server? If not, you either need to add your certificate as a trusted one, or set the option `verify` to `False` See [https://github.com/Vaelor/python-mattermost-driver/blob/master/README.rst#usage](https://github.com/Vaelor/python-mattermost-driver/blob/master/README.rst#usage) ‘optional Options’ > Optional options > These options already have useful defaults or are just not needed in every case. In most cases, you won’t need to modify these, especially the basepath. > If you can only use a self signed/insecure certificate, you should set > verify to False.

> [@rony94](#): > > foo = Driver({ > ‘url’:‘10.10.10.6’, > ‘scheme’:‘https’, > ‘port’:8065 > }) If you do not use a certificate, you don’t use https, so you should have `scheme: http`. Also, if you do not use https, you don’t need to bother with `verify` - the option does nothing when http is used. ---

Well another problem could be your webserver setup. `Errno [111] Connection refused` could also mean there is nothing listening on your specified location. Looking at the curl request you had in your initial post, is the port `8065` correct? > [@rony94](#): > > I tried that curl --insecure -i -X POST -H ‘Content-Type: application/json’ -d ‘{“text”: ‘python /home/scripts/python-script.py’}’ [https://10.10.10.6/hooks/84kk9emcdigz8xta1bykiymn5e](https://10.10.10.6/hooks/84kk9emcdigz8xta1bykiymn5e) > > and got that error > > {“id”:“Unable to parse incoming data”,“message”:“Unable to parse incoming data”,“detailed\_error”:“”,“request\_id”:“fpnmfds8zifziyc85oe5eyf3pa”,“status\_code”:400} ---

Pip points to the version for python2 in your setup. The mattermostdriver works only with Python \>= 3.4 - that is why you get the exception > Exception: python-mattermost-driver requires Python \>= 3.4. ---

yes listen address in mattermost is 127.0.0.1:8065 ---
**Author:** ![Vaelor](https://sea2.discourse-cdn.com/flex020/user_avatar/forum.mattermost.com/vaelor/32/1951_2.png) [@Vaelor](https://forum.mattermost.com/u/Vaelor)\ **Post date:** [April 16, 2018, 2:43pm UTC](https://forum.mattermost.com/t/using-python-script-in-incoming-webhook/4749/17 "2018-04-16T14:43:46Z")
If the listen address is `127.0.0.1`, your url would be incorrect ( `‘url’:‘10.10.10.6’` ) There are two possibilities I see there: You have the mattermost server and the script running on the same server. In this case, you should probably use `127.0.0.1` as the url, too. Or, the python script is not running on the same server as mattermost with for example nginx in front, so you can access mattermost over port 80/443, and redirect everything to 127.0.0.1. Then you ofc need to use `10.10.10.6` with port 443 (https) and not 8065. ---

Beautiful 🙂 No errors anymore but there is no output in the channel. I have a feeling it has something to do with the scheme . Because I have mattermost with untrusted certificate, but if I put scheme https with verify false or true it gives an error. I will try these steps when I step up my new mattermost vm [Next page](https://forum.mattermost.com/t/using-python-script-in-incoming-webhook/4749.md?page=2)
