First, make sure you are logged into the Creative Automation platform at ca.vidmob.com.
From there, access Creative Automation, via the side menu on the left side of your browser, or by clicking "Create Files" in the Dashboard.
With the template on the platform selected, you have the option to generate creatives by "Upload Spreadsheet" or "New Form".
"New Form" is ideal for small quantities. With this method, the variables will be filled manually on the Data Feed screen.
"Uploading a Spreadsheet" is ideal for large amounts of unfolding. You can download an example file of the chosen template and fill in several lines at once using the functions of a spreadsheet editor.
