Daily JokeAPI Joke Bot for Slack & WhatsApp (n8n Workflow)

Bring daily laughs to your team—automatically

This Daily JokeAPI Joke Bot for Slack & WhatsApp (n8n Workflow) pulls a family-friendly joke from JokeAPI every day, formats it for each channel, and posts it to your Slack channel and sends it to your WhatsApp recipient—optionally after a random surprise delay.

What this workflow does

• Runs on a daily schedule: Uses a Schedule trigger to start the workflow at your configured hour (with workflow time zone support).
• Loads your settings: Slack channel, joke categories, WhatsApp recipient number (international format), and a configurable max random delay.
• Surprises everyone: Waits a random number of minutes from 0 up to your maximum before posting.
• Fetches a safe-mode joke: Calls JokeAPI using safe-mode and applies blacklist flags to filter sensitive content.
• Formats for each platform: Creates separate Slack and WhatsApp message variants, correctly handling both one-liner jokes and setup/punchline jokes.
• Posts in parallel: Sends the Slack message to your selected channel and the WhatsApp message to the configured recipient at the same time.

Use cases

• Keep remote teams engaged with a daily joke posted directly into Slack.
• Send a morning “pick-me-up” to a leader, support channel, or community via WhatsApp.
• Test and showcase practical n8n automation workflows integrating external APIs and multi-channel notifications.
