Automate Email Template Sync Between Dartagnan & Braze with n8n

What This Workflow Does

This workflow keeps email templates in Dartagnan and Braze in sync. It fixes the problem of missed or old content updates by checking campaigns and templates. The result is consistent emails and saved time by running every 5 minutes automatically.

It logs into Dartagnan using OAuth2 and gets the access token. Then it gets the list of projects and their campaigns. Next, it checks Braze for email templates already there. It compares campaign and template names to find matches or new items.

Updated campaigns have their images fixed and HTML prepared, then the workflow updates Braze templates. New campaigns get created as new templates in Braze. This way, the two platforms stay up to date without manual work.

Customization Ideas

• Change the Schedule Trigger node frequency to run the workflow less or more often according to your team needs.
• Modify the campaign filter logic to handle multiple campaigns per project, using n8n nodes like SplitInBatches.
• Edit the email subject lines in the update and create HTTP nodes to add new marketing text or variables.
• Add alert nodes like Slack or email to notify the team if an error occurs during sync.
• Improve the Embed image in HTML code node to handle different media types such as videos or gifs.

Troubleshooting Common Issues

• 401 Unauthorized Errors
  Make sure Dartagnan and Braze credentials are correct in the Assign Credentials node and tokens refresh properly.
• No Data or Empty API Responses
  Check all API URLs in HTTP Request nodes match Dartagnan and Braze latest documentation.
• Templates Not Updating
  Verify the update check compares timestamps correctly and uses exact JSON paths.
• Image URLs Not Replacing
  Edit the JavaScript regex in the Embed image in HTML code node to match all supported image formats.

Pre-Production Checklist

• Confirm Dartagnan API credentials and Braze API key are entered exactly as required.
• Test each HTTP Request node alone to verify correct data retrieval.
• Check the Token Request node outputs a fresh access token before running other steps.
• Ensure the schedule trigger fires on your desired timing.
• Run a manual test sync with recent Dartagnan campaigns to confirm Braze templates update properly.
• Backup existing Braze email templates before enabling automation to allow rollback.
