This workflow:

Imports a brand
Waits and checks if import is complete (loops until done)
Generates an email
Waits and checks if generation is complete (loops until done)
Exports the final HTML

Advanced Use Cases

Shopify Multi-Store Automation

For processing multiple Shopify stores from a spreadsheet, see this advanced workflow:

Prepare Your Data

Create a Google Sheet with columns: Store URL, Store Owner Email, Store Name

Read from Sheet

Use n8n’s Google Sheets node to read all stores

Loop Through Stores

Use “Split in Batches” node to process each store one at a time

For Each Store

Import brand: POST /v1/projects/import
Connect Shopify: POST /v1/shopify/connect
Generate email: POST /v1/projects/emails/generate
Send test email: POST /v1/emails/test/send

Note: To send test emails, make sure your API key has the EMAIL_SEND permission enabled in Migma Settings → Developers → API Keys.

Using Webhooks Instead of Polling

For better performance, use Migma webhooks instead of wait/check loops:

Add a Webhook node in n8n and copy the webhook URL
In Migma Settings → Developers → Webhooks, create a webhook
Subscribe to events: project.import.completed and email.generation.completed
Your n8n workflow will be triggered automatically when events occur

Tips

Passing Data Between Nodes

Use n8n expressions to reference previous node data:

{{ $json.data.projectId }} - Access projectId from current node
{{ $('Import Brand').item.json.data.projectId }} - Access data from specific node

Handling Errors

Add an Error Trigger node to catch failures and send alerts or retry logic.

Batch Processing

Use Split in Batches node to process multiple items from spreadsheets or databases.

Export Formats

Available export endpoints:

/v1/export/html/{conversationId} - Standard HTML
/v1/export/klaviyo/{conversationId} - Klaviyo format
/v1/export/mailchimp/{conversationId} - Mailchimp format
/v1/export/mjml/{conversationId} - MJML format
