Using Plugin Output (API JSON) in Nintex NAC Form Controls

Hi Team,

I am working with Nintex Automation Cloud (NAC) forms and have created a custom plugin that fetches user/customer data from an API and displays it in a searchable dropdown.

When a user selects a record from the dropdown, the plugin successfully returns the selected data in JSON format.

Example output:

[
  {
    "CustomerName": "AGILE ARBOR PTY LTD",
    "CustomerNo": "1059530",
    "PhoneNo": "02 6334 2544",
    "Address": "344 LIMEKILNS ROAD"
  }
]

However, I am facing an issue while trying to use this output inside the form controls.

My requirement:

• When a user selects a record from the plugin, I want to:

  • Display the selected values in other form controls (e.g., Customer Name, Phone, Address)

  • Save the JSON data into a SharePoint column
