Yes! Use the list_form_fields tool and provide the Form ID. Your agent will retrieve the complete structure, including labels and field types.
How do I retrieve the latest submissions for a form?
Run the list_form_entries query with your Form ID. The agent will return a paginated list of user submissions, which you can then inspect individually using get_entry_details.
Is it possible to check the API connection status?
Absolutely. Use the get_api_status or test_formbuilder_auth tools to verify your credentials and ensure the agent can communicate with the 123FormBuilder service.
