This article provides a complete, practical walkthrough of the Googlecontacts Schedule Send Scheduled n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   In a world full of meetings, to-do lists, and constant distractions, remembering important personal milestones like birthdays can be challenging. Whether you're managing a large team, trying to stay socially engaged with clients, or simply want to send thoughtful messages to friends and colleagues, automating reminders can save time and strengthen relationships.
   
   Enter n8n — the open-source, node-based workflow automation tool. In this article, we’ll walk you through a customized n8n workflow that automatically reads birthdays from your Google Contacts and sends thoughtful reminders to a Slack channel every morning.
   
   🏗️ Overview of the Workflow
   
   Titled “Send Daily Birthday Reminders from Google Contacts to Slack,” this n8n workflow bridges two powerful platforms — Google Contacts and Slack — to create a seamless birthday notification system. Here’s what it does:
   
   - Runs every day at 8 AM
   - Pulls all contact data from Google Contacts
   - Filters out contacts with no listed birthday
   - Checks if today matches any contact's birthday
   - Sends a Slack message highlighting whose birthday it is
   
   This automation ensures you’ll never be caught off guard again.
   
   ⏰ Step 1: Schedule Trigger
   
   The automation begins with the Schedule Trigger node, which is configured to run the workflow every day at 8 AM. This daily cadence ensures the system is always checking for new birthdays at the start of your workday.
   
   🔗 Step 2: Pull Google Contacts
   
   The next step uses the Google Contacts node to fetch all your contacts, including key fields like:
   
   - Email addresses
   - Birthdays
   - Names
   - Nicknames
   
   By selecting "Return All" and including birthdays explicitly, the workflow gathers everything it needs to proceed.
   
   🧹 Step 3: Filter Contacts With Birthdays
   
   Not every contact in your Google account will have a birthday listed. The Filter Contact node ensures that only those with available birthday data are passed on to the next step. This minimizes unnecessary processing and keeps your Slack messages focused and relevant.
   
   📅 Step 4: Match Today's Date
   
   Now comes the logic test. The "If" node checks whether the birthday field for any contact matches the current date. It uses a strict conditional to compare today’s date (dynamically calculated) with each contact’s date of birth.
   
   This node is the heart of the workflow — the gatekeeper determining who gets a Slack shout-out and who must wait until their turn comes around.
   
   💬 Step 5: Send Slack Message
   
   Finally, we reach the Slack node. This block sends a celebratory notification to a pre-set Slack channel formatted as:
   
   "Today is John Doe’s birthday! 🎉"
   
   You can personalize this message further with emojis, GIFs, or mention tags to notify specific team members. It’s a highly customizable solution that turns a simple nudge into a moment of celebration.
   
   🎯 Use Cases and Benefits
   
   This automation is perfect for:
   
   - HR teams wanting to celebrate employee birthdays
   - Team leaders aiming to boost morale
   - Freelancers or salespeople who want to maintain personal connections with clients
   - Anyone looking to remember birthdays without relying on social media platforms
   
   By integrating this into your daily workflow, you build an environment of appreciation and personal connection — with zero manual effort.
   
   🔧 Customization Options
   
   Here are a few ideas to make this workflow your own:
   
   - Add a delay function to stagger messages throughout the day
   - Enrich Slack messages with fun facts or personalized wishes
   - Use the Twilio node to send SMS reminders instead of (or in addition to) Slack messages
   - Link to a team birthday document or celebration calendar
   
   🔐 API Credentials Needed
   
   To activate this workflow, you’ll need to authenticate with:
   
   1. Google Contacts API using OAuth2 credentials
   2. Slack API (via Slack OAuth2) with access to the target channel
   
   These credentials allow n8n to securely pull contact data and send messages on your behalf.
   
   📦 Wrapping Up
   
   Automating birthday notifications might seem like a small gesture, but it contributes immeasurably to a vibrant, connected workplace. With n8n, you don’t need to be a developer to build powerful, personalized automations like this one. By integrating Google Contacts and Slack together in a single workflow, you’ve turned a thoughtful act into a reliable routine.
   
   Get started with this workflow today, and never miss the opportunity to celebrate someone important again.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
