import json
import requests

# Set the webhook_url to the one provided by Slack when you create the webhook at https://my.slack.com/services/new/incoming-webhook/
webhook_url = 'https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX'
slack_data = {'text': "Sup! We're hacking shit together @HackSussex :spaghetti:"}

response = requests.post(
    webhook_url, data=json.dumps(slack_data),
    headers={'Content-Type': 'application/json'}
)
if response.status_code != 200:
    raise ValueError(
        'Request to slack returned an error %s, the response is:\n%s'
        % (response.status_code, response.text)
    )

Hi, this is working example:

import requests

def send_slack_notif():

    url = 'YOUR_SLACK_WEBHOOK_URL'
    payload = {
        "blocks": [
            {
			    "type": "section",
			    "text": {
				    "type": "plain_text",
				    "text": ":red_circle: This is a plain text section block.",
				    "emoji": True
			    }
	}
        ]
    }
    r = requests.post(url, json=payload)
    
send_slack_notif()
