Automate Shopify Order Fulfillment with n8n Workflow

What This Automation Does

This workflow takes unfulfilled Shopify orders older than 24 hours and automatically marks them fulfilled.
It finds the right fulfillment order IDs and sends fulfillment notifications.
This helps to save time, reduce errors, and speed up letting customers know their orders are done.

The workflow gets unfulfilled orders via Shopify API, filters old orders, loops through them, fetches fulfillment orders, and creates fulfillment.
It works in batches so big order lists don’t overload the system.

Who Should Use This Workflow

This automation fits Shopify store owners who sell digital items or gift cards.
It suits those who get many orders each day and want to stop manual fulfillment work.

Users must have Shopify API access and some knowledge of n8n to set it up.
Also good for anyone wanting to reduce mistakes and speed up customer updates.

Beginner Step-by-Step: How to Use This Workflow in n8n

Step 1: Import the Workflow

1. Download the workflow file using the Download button on this page.
2. Open your n8n editor.
3. Use the menu to select “Import from File” and upload the downloaded workflow file.

Step 2: Configure Credentials and Settings

1. Open the Set node named “Set Global” and input your Shopify store ID exactly (example: “myawesome-store”).
2. Go to the Shopify node and HTTP Request nodes. Add your Shopify API access token credentials.
3. If needed, update any IDs, emails, or other variables in nodes based on your store’s setup.

Step 3: Test the Workflow

1. Run the workflow manually using the Manual Trigger node.
2. Check the output to confirm orders are fetched and marked fulfilled correctly.

Step 4: Activate for Production

1. Switch to the Schedule Trigger node to run this workflow automatically at intervals you set.
2. Save and activate the workflow to automate fulfillment without manual work.

Using the workflow after import requires no deep coding. Just configure credentials, store ID, test it, and activate.
If using self-host n8n, ensure connectivity to Shopify API is set up.

Customization Ideas

• Turn off customer notification by setting “notify_customer” to false in fulfillment POST request.
• Change the 24-hour filter to other hour values to fit your store’s pace.
• Modify looping logic to fulfill multiple or partial fulfillment orders per main order by iterating all IDs.
• Adjust schedule frequency in the Schedule Trigger node for hourly, daily, or custom runs.

Troubleshooting

• HTTP Request node returns 404 Not Found: Check store ID in Set node, confirm correct API version in URL.
• No orders retrieved from Shopify node: Verify Shopify API credentials and that unfulfilled orders exist in store.
• Workflow stops after first order: Ensure the continuation branch from SplitInBatches node connects back to loop nodes correctly.

Pre-Production Checklist

• Confirm Shopify API credentials are valid in n8n credentials settings.
• Manually test the workflow to confirm orders are fetched and filtered correctly.
• Verify that the 24-hour filter works as intended by checking timestamps.
• Test fulfillment creation for a single order before running large batches.
• Backup Shopify order data, or export it as fallback before running bulk fulfillment automation.

Deployment Guide

Once testing passes, activate the Schedule Trigger node.
This runs the workflow automatically at your chosen intervals without manual steps.

Monitor workflow runs in n8n UI for possible errors or retries.
Remember to rotate API keys regularly to keep Shopify connection secure.
