## Introduction
In fast-moving startup environments, daily standups are essential for team alignment and productivity. However, remembering to send timely reminders for standups can be cumbersome for operations teams, leading to missed meetings or delays. Automating daily standup reminders on Slack ensures consistency and frees up managerial bandwidth.
This tutorial walks you through creating a robust automation workflow using **n8n**, a powerful open-source workflow automation tool. We will build an automation that sends tailored daily standup reminders to your Slack workspace at a specific time every working day.

## What Problem Does This Solve and Who Benefits?
**Problem:** Manual reminders for daily standups are error-prone, time-consuming, and can disrupt team workflows if missed or sent late.
**Beneficiaries:**
– Operations teams managing workflows and meetings
– Engineering and product teams attending daily standups
– Startup CTOs seeking to improve operational efficiency
Automating the reminder process reduces human error, enforces meeting discipline, and increases the productivity of distributed teams.

## Tools and Integrations
– **n8n:** An open-source workflow automation tool to orchestrate the process
– **Slack:** For sending standup reminder messages
Optional integrations for extended functionality:
– Google Calendar (to check non-working days)
– Airtable or Google Sheets (to dynamically fetch team member list or reminder messages)

## How the Workflow Works: Trigger to Output
1. **Scheduled Trigger:** The workflow activates at a configured time (e.g., 9:00 AM every weekday).
2. **(Optional) Check Date:** Confirm today is a working day (skip weekends/holidays).
3. **Compose Reminder Message:** Construct a reminder message tailored for the team/channel.
4. **Send Slack Message:** Post the reminder to the designated Slack channel.
Each step is implemented with dedicated n8n nodes, ensuring modularity and easy maintenance.

## Step-by-Step Tutorial
### Prerequisites
– Access to an n8n instance (self-hosted or cloud)
– Slack workspace and bot token with permissions to send messages
– Basic familiarity with n8n interface and Slack API
### Step 1: Create a New Workflow in n8n
– Log in to your n8n editor UI.
– Click on “New Workflow”.
– Name it “Daily Standup Reminder – Slack”.
### Step 2: Add a Cron Node to Schedule Trigger
– Add a **Cron** node.
– Set it to run at your preferred reminder time (e.g., 9:00 AM).
– Configure it to run every weekday:
– Set Days of Week: Monday to Friday.
– Set Timezone to your team’s timezone.
### Step 3: (Optional) Add a Holiday Checker
– For more robustness, add an HTTP Request node to hit a public holiday API (e.g., Google Calendar API, or a free holiday API).
– Use this to decide if the reminder should be skipped on holidays.
– Use an **IF** node in n8n to filter the workflow based on whether today is a holiday.
### Step 4: Add a Set Node to Define the Reminder Message
– Add a **Set** node after the Cron (or IF) node.
– Define message properties such as:
– channel: Slack channel ID or name (e.g., #standup)
– text: “Good morning team! This is your friendly daily standup reminder. Please join the standup meeting at 10:00 AM.\nIf you have updates, be prepared to share them.”
– optionally, you can add emojis and formatting.
### Step 5: Add Slack Node to Send Message
– Add Slack node configured with your Slack bot credentials.
– Select **Post Message** operation.
– Map the **channel** and **text** fields from the Set node.
### Step 6: Test the Workflow
– Execute workflow once manually to verify message delivery.
– Check Slack channel for the reminder.
– Review n8n execution logs for any errors.
### Step 7: Activate the Workflow
– Once tested successfully, activate the workflow.
– It will now run every weekday at the scheduled time.

## Detailed Breakdown of Each Node
1. **Cron Node:**
– Purpose: Schedules the workflow’s execution.
– Configuration:
– Mode: Every Weekday
– Time: Morning time of reminder
– Timezone: Important to match team’s location to avoid sending at odd hours
2. **Holiday Checker Node (Optional):**
– Sends an HTTP GET request to a defined API.
– Parses response to check if today is a holiday.
– Connected to an IF node that determines if workflow continues.
3. **IF Node:**
– Evaluates holiday flag.
– Passes execution only on working days.
4. **Set Node:**
– Defines static reminder message and target Slack channel.
– Can be enhanced to dynamically pull team names or meeting links.
5. **Slack Node:**
– Uses Slack API to post the message.
– Requires properly scoped Slack app credentials (chat:write permission).

## Common Errors and Tips for Robustness
– **Slack API Rate Limits:** Ensure your bot respects rate limits; this simple workflow is unlikely to hit these but keep in mind if scaling.
– **Authentication Failures:** Check Slack bot tokens and permissions.
– **Timezone Mismatches:** Configure Cron node timezone correctly to avoid off-hours reminders.
– **Holiday API Availability:** If using external APIs to check holidays, implement fallback paths or cache results.
– **Channel ID vs Name:** Using channel IDs instead of names reduces ambiguity and errors.
– **Message Formatting:** Use Slack’s Block Kit for richer formatting if needed.
—
## How to Adapt or Scale the Workflow
– **Dynamic Recipient List:** Fetch users from a database or Google Sheets to send personalized DMs instead of channel messages.
– **Multiple Teams:** Copy and parameterize workflow to send different reminders to various Slack channels.
– **Meeting Links and Agendas:** Integrate Google Calendar or Airtable to include meeting links or agenda dynamically.
– **Error Notifications:** Add nodes to notify admins if the workflow fails.
– **Multi-Platform Notifications:** Extend workflow to notify via email or SMS using integration nodes.

## Summary
Automating daily standup reminders on Slack with n8n streamlines communication and ensures meetings happen on time without manual effort from the operations team. This guide set up a simple yet effective workflow using n8n’s Cron and Slack nodes, combined optionally with holiday checks for added reliability.
By following this tutorial, startup teams can embrace automation to increase operational efficiency and team discipline. Enhancements such as dynamic message content, multi-channel support, and integration with calendars can make this automation even more powerful.

## Bonus Tip: Use Slack’s Workflow Builder for Lightweight Reminders
If your automation requirements are simple, consider Slack’s built-in Workflow Builder for lightweight reminder automations without external dependencies. However, n8n offers superior flexibility, scalability, and cross-tool integrations, ideal for more complex operations.

With this foundation, your operations team can ensure daily standups run smoothly, facilitating better team collaboration and productivity.
