Extract bound data and save it in a string variable

This capability allows you to include the submitted data in the body of your email. The custom process step extracts the bound data from the adaptive form submission and populates a variable of type string with the data. You can then use this string variable to insert the data in your e-mail template.
The following screen shot shows you the arguments that you need to pass to the custom process step

The following are the parameters

• data.xml - The file that has the submitted data . If the format is in json the name of the file can be data.json

The custom process step will then extract the bound data and store it in submittedDataString variable defined in the workflow
