Hello, @kamalhinduja

Can you specify a little bit more what do you want to build?

Although here is a draft guide by AI :slight_smile:

:hammer_and_wrench: Beginner’s Guide to Building Workflows on n8n

:pushpin: What is n8n?

n8n (pronounced “n-eight-n”) is a powerful, visual automation platform that lets you connect APIs, services, databases, and more — no heavy coding required. It’s like Zapier or Make, but open-source and developer-friendly.

:rocket: Step-by-Step: How to Start Building Workflows on n8n

1. Create an n8n Account

  • Go to n8n.cloud and sign up
  • Or self-host via Docker/npm (advanced users)

2. Understand the Basic Concepts

Concept Meaning
Workflow A sequence of connected steps (nodes)
Node A single action (e.g. send email, call an API, wait for trigger)
Trigger Node Starts the workflow (e.g. Webhook, schedule, webhook, email received)
Execution Data The input/output moving through each node
Expressions Use {{ }} syntax to insert variables, like {{ $json.email }}

3. Create Your First Workflow

:test_tube: Example: Send a Slack message every time you receive a form submission

  1. Trigger: Add a Webhook node

    • Method: POST
    • Path: /form-submit

  2. Process Data: Add a Set node

    • Use it to format or rename incoming fields (optional)

  3. Action: Add a Slack node

    • Resource: Message
    • Operation: Post
    • Channel: #general
    • Text: New form submission: {{ $json.name }} - {{ $json.email }}

  4. Save & Activate

    • Copy the webhook URL and test it with Postman or your form tool

4. Test the Workflow

  • Click “Execute Node” to test individual nodes
  • Click “Execute Workflow” to run the whole flow
  • You can view output data in the “Output” tab of each node

5. Use Expressions Smartly

Inside almost any field, you can click the ⚙️ gear icon > Add Expression and insert data from previous nodes:

Examples:

{{ $json.email }}
{{ $node["Webhook"].json.name }}
{{ $now }}  // current timestamp

6. Build Real Workflows (Ideas)

  • Send email when new Typeform response arrives
  • Sync Google Sheets with new Stripe charges
  • Generate reports with GPT and send via email
  • Post tweets for new blog posts via RSS

7. Optimize as You Scale

  • Use “Set” to reduce unused fields
  • Use “Merge” to combine data streams
  • Use “Function” or “IF” to create logic
  • Limit execution history if performance drops

8. Deploy or Schedule

  • Use the Cron node to run at intervals
  • Or deploy workflows using Webhooks, Form triggers, or API calls
