Verified import paths — ran on the pinned version, not inferred.

Slack
✓ from slack_webhook import Slack
✗ from slackwebhook import Slack
The package name uses underscores: slack_webhook, not slackwebhook.

Sends a simple text message to a Slack channel via an Incoming Webhook URL.

from slack_webhook import Slack webhook_url = os.environ.get('SLACK_WEBHOOK_URL', '') slack = Slack(url=webhook_url) slack.post(text="Hello, Slack!")
Debug
Known issues
gotchaThe webhook URL passed to Slack() must be the full URL, including 'https://hooks.slack.com/services/...'. Omitting the protocol or path will cause a connection error.
fix
Ensure the URL is copied exactly from the Slack App configuration.
affects: all
gotchaThe Slack client does not verify the webhook URL or handle errors gracefully. Invalid URLs or network issues may raise unhandled exceptions.
fix
Wrap calls in try/except blocks and check the response status.
affects: all
deprecatedThe library is not actively maintained; last release was in 2020. Consider using the official slack-sdk library for webhooks.
fix
Migrate to slack_sdk.webhook.WebhookClient from the slack-sdk package.
affects: >=1.0.0
