How to Preselect Radio Buttons, Checkboxes, Dropdowns, and Phone Fields via API trigger_inputs in Maestro Webforms?

Hello everyone,

We’re currently working on passing values from our website into a DocuSign Maestro webform via API trigger_inputs, and while we’ve had success with text fields and date fields, we’re running into challenges with other field types.

Specifically, we want to pre-select a radio button option so that when the webform loads, the correct option is already chosen. For example:

• Gender field (radio buttons): Options are Male, Female, Others. We’d like to pre-select Male.

We suspect this challenge may apply similarly to dropdowns, checkboxes, and phone number fields as well.

Has anyone implemented this successfully? Could you please share examples of the correct variable types or payload structure required to map these field types (radio buttons, checkboxes, dropdowns, phone)?

I’ve attached screenshots for reference. Any guidance or working examples would be greatly appreciated!

Thanks in advance.
