Form API Reference

Here you can find the reference for the Form API and learn how to establish a connection to the form.

Establish a Connection

The first step for using the Form API is establishing a connection to the form. To do that, use the sample code below with the ID of the form you're working with.

            YTFeedbackForm.getClientJSApi('680e7600-000f-4029-bfe9-ddf479c73ef7').then(async form => {
                // Your code goes here
            })
        

You can get the form ID from the embed code for the form.

Predefined Fields

There are three predefined form fields that you can refer to by their names:

email
summary
description

Sample code:

            // Setting the email value to jane.doe@example.com.
            form.setBlockValue('email', 'jane.doe@example.com');

            // Setting the summary.
            form.setBlockValue('summary', 'Assistance Required');

            // Setting the description.
            form.setBlockValue('description', 'I need assistance, please get back to me.');
