Daily Size It Up Puzzle Preview to Slack with n8n Workflow

Send today’s “Size It Up” brain teaser to Slack—automatically, spoiler-free

The Daily Size It Up Puzzle Preview to Slack with n8n Workflow posts a daily, spoiler-free preview of the free Size It Up size-guessing game to your team’s Slack channel—complete with a play link. It fetches the day’s puzzle from the public API and shares only the five object-name pairings.

What this workflow does

• Runs on a 24-hour schedule (or via a manual trigger for testing).
• Sets the puzzle date based on the workflow’s timezone, ensuring your “daily” rollover matches how you define the day.
• Loads the target Slack channel (using your configured YOUR_SLACK_CHANNEL_ID).
• Requests the daily “regular” puzzle for that date from the Size It Up public API.
• Validates the API response and builds a spoiler-free Slack message containing only the five object-name pairings and a link to the game.
• Posts the formatted daily puzzle to Slack.

Use cases

• Keep teams engaged with a quick daily game without manual sharing.
• Run a daily “guessing challenge” for remote work communities in Slack.
• Preview daily content from Size It Up on a consistent schedule for SaaS operators and automation engineers.
• Test formatting and Slack posting using the Manual Trigger before going live.

Technical details

• Scheduler: Schedule Trigger (24-hour cadence) + Manual Trigger for testing.
• Core logic: uses Set and Code to configure date/channel and format the spoiler-free message.
• HTTP integration: HTTP Request to the Size It Up public API (no account/API key required).
• Slack posting: Slack node using Slack OAuth2 credentials with permission to post to your chosen channel.
• Notes/supporting workflow parts: includes nodes such as Sticky Note for workflow clarity.

To set it up, add your Slack OAuth2 credential, ensure the Slack app is added to the target channel, replace YOUR_SLACK_CHANNEL_ID, and adjust the workflow timezone so the daily puzzle aligns with your preferred rollover time.
