I need to retrieve a simple Boolean answer on a data extension asynchronously.
I believe that I can make an ajax call to a processing page and retrieve that data. However, I'm new to salesforce and AMPscript, and have no idea to return a value or print out a JSON from a data extension.
All my searches on google keep pushing me to Java or Apex API calls. If that is the only way to do this, then let me know so I can abandon this project.
