Change the username of incoming webhook message

I use the following code snippet to send notification message to an incoming webhook URL:

from slack_sdk.webhook import WebhookClient

webhook_url = "https://hooks.slack.com/services/T0..."
webhook_sync = WebhookClient(webhook_url)
response = webhook_sync.send(text="Test notification")

My question is how can I specify the username of that message like Gitlab does on its slack notification settings? I couldn’t find any parameter to do that.

@agn-7 Thanks for the reply. So, in this case,

The username parameter used to be available for legacy incoming webhooks: https://my.slack.com/apps/A0F7XDUAZ-incoming-webhooks

as I mentioned above, you can still create the legacy webhook, which supports username and other parameters. It’s not recommended from a long-term maintenance perspective, but it works for now (and at least until the sunset of legacy custom integrations although we haven’t decided anything on the timeline).

Since we don’t have anything further to share on this topic, let us close this issue now. Thanks again for writing in!

@agn-7 Utilizing a Web API such as chat.postMessage is completely different from Incoming Webhooks. Please refer to the document for more details: https://slack.dev/python-slack-sdk/web/index.html
