You are also able to store the print-ready file in a cloud like Dropbox or AWS S3, when an order is created.
Go the Dropbox App Console and create a new App.
In the next screen you can configurate the App.
After the App is created, you will be redirected in the App settings. There you can generate an Access Token.
Copy the Access Token and paste it in the "Dropbox Access Token" option in the Automated Export settings of Fancy Product Designer.
You can even store the print-ready files in a bucket of AWS S3. Therefore you need to create an user with access to your bucket in the IAM console. After that you need to copy the Access Token and Secret and paste it in the Automated Export settings.
