Fix & Resend Guest Order Emails in Magento 2 via REST API

Description

This powerful n8n automation workflow is built for Magento 2 store owners and support teams who need to quickly correct guest customer email addresses and automatically resend order confirmation emails — all without logging into the Magento Admin Panel.

🧩 What This Workflow Does:
🔄 Automates Magento 2 Admin Token Generation for secure REST API access.
✏️ Edits the email address on guest orders by updating both customer_email and billing_address.email fields using the Magento 2 Order API.
📧 Triggers the Magento 2 order confirmation email using the official /V1/orders/:id/emails endpoint.
🧠 Can be triggered manually or automatically from a form, CRM, failed email webhook, or helpdesk system.
📝 Logs actions and results to keep track of which emails were updated and which confirmations were resent.

✅ Why Use This n8n Workflow?
No more manual edits via Admin Panel.
Ideal for support teams fixing typos like @gamil.com or @yahho.com.
Seamless experience for customers who never received their order confirmation.
Easily extendable — connect to your existing n8n ecosystem (forms, Slack, HelpDesk, Airtable, etc.)

💼 Use Cases
🔧 A customer checks out as a guest and provides the wrong email — this automation fixes it in seconds.
📦 Support team gets a ticket: “I didn’t receive my confirmation email” — plug in the new address and let the workflow handle the rest.
🤖 Ecommerce operators who want to automate email recovery and cleanup workflows with precision and audit logs.

🔑 Credentials Used
