what to call on
slack_webhook_block
to get the original URL?

I need to point out that this is actually by design - there isn't a way to retrieve the original, unobfuscated Slack webhook URL from a SlackWebhook block. This is a security feature to prevent accidental exposure of sensitive credentials. When you load a SlackWebhook block and try to access the webhook URL, you'll only see an obfuscated version. The actual URL is encrypted in storage and only used internally when sending notifications. If you need to verify the webhook works, the best approach is to: 1. Use the
.notify()
method to send a test message 2. Store the webhook URL separately in a secure location for your records 3. If you need to update the webhook, you'll need to create a new block with the new URL This is consistent with how Prefect handles other sensitive credentials - they're intentionally one-way encrypted for security purposes.
