Once you have chosen to connect your iFormBuilder Account, you will be prompted to give your new account a name or label to be used within Zapier. It doesn't matter what you name it, but it does matter that you paste into the Private Database Name!
Once you have added the required fields and pressed Continue, a pop-up window will appear asking for you to log-in to your iFormBuilder account. *Remember you must log-in as a Server Admin.
After logging in successfully, you will be brought back to Zapier and receive confirmation that the Account is working. Now you can continue building out your Zap! All form data (Subforms included!) will be displayed.
