The problem

Your business tools do not connect, so people copy information from one to another by hand.

How this automation solves it

Demonstrates a credential-free REST API sync with bounded retries, record normalization, schema validation, and sanitized failure output. It runs on a manual run, so the work happens without anyone doing it by hand.

What changes in your business

  • Your tools connected to each other
  • Manual copying removed
  • Fewer mistakes and faster work

Use these to connect the other tools your business relies on, from CRMs and calendars to payments and analytics. It's most useful for engineering/workflow reliability teams.

Step-by-step setup (free)

  1. 1

    Get the file

    Click "Add to cart", check out free with your details, and download the workflow file.

  2. 2

    Import it into n8n

    Open n8n (n8n Cloud or your own server), create a new workflow, then choose "Import from File" from the menu and select the file. You can also paste the file contents straight onto the canvas.

  3. 3

    Connect your accounts

    This workflow does not need any app accounts beyond n8n itself.

  4. 4

    Set up the trigger

    The workflow starts when you click "Execute workflow". To run it automatically, swap the manual trigger for a Schedule Trigger.

  5. 5

    Replace the placeholders

    Look for placeholder values such as you@example.com, sheet names, folder IDs and URLs, and replace them with your own.

  6. 6

    Test, then switch it on

    Run the workflow once with test data and check every node turns green. Then turn on the Active toggle so it runs by itself.

These projects are adapted from awesome-n8n-templates by Enes Cingoz and the original workflow authors, shared under CC BY 4.0. Changes made: removed sample data and saved credential IDs, replaced hard-coded email addresses and calendar IDs with placeholders, and rewrote some descriptions. Hunain Nasir did not create the original workflows and they are not endorsed by their authors. Always review and test a workflow before using it with real data.
