Mattermost WebHook

Hello,

is there anyone here who is familiar with the Mattermost WebHooks?

I have created a WebHook and use it for info messages from a CRM.
For this we created and executed a python file at an event.
Unfortunately, my user is always the sender.
Is it possible to vary the sender?

Does anyone possibly know a description that goes further than the,
which is on the help page?

Thanks,

Alexander Altenhoff

import json
import requests
url = 'https://webadresse:8234/hooks/hook_string' 
payload = {"channel": "@empfänger", "username": "Info vom CRM", "text": "Info an:  Hier steht die Information!!!" } 
headers = {"content-type" : "application/json"}
r = requests.post(url, data=json.dumps(payload), headers=headers) 
print (r.text) ```

As per your signature you are still on Mattermost 4.4.2. Why are you so far behind? Also Core, WebApp and Z-push have seen quite some releases meanwhile…

as for your question. it seems you are looking for https://docs.mattermost.com/administration/config-settings.html#enable-integrations-to-override-usernames
