How to split fullname into firstname and lastname in the public booking page?

By default, Cal ID booking page has a fullname text input field for the scheduler to put their name in. This usually works just fine for most people. However, at times, it is preferable to take the firstname and lastname of the scheduler as separate inputs in the booking form.

Cal ID provides the option to split the fullname input field in the booking form into firstname and lastname. To do that, you can do the following:

• Head to the event type where you wish to split the fullname into firstname and lastname >> Edit
• Click on the Advanced tab.
• Scroll to the Booking questions section.
• Click on the Edit button in front of "Your name"

• In the dialog that opens, click on the toggle that says Split "Full name" into "First name" and "last name".

• Fill the label and optional placeholder values, and click on save.

• Remember to click on the save button in the event type settings as well.
• Head to the public booking page of this event type, you will notice the fullname is now split into firstname and lastname with the labels provided by you.

You're all set!

Please note that in case of API requests, your usual responses object

"responses": {
        "name": "John Doe",
        "email": "john.doe@example.com",
        "location": {
            "optionValue": "",
            "value": "Acme Industries"
        }
    }

will now be updated to allow name to be converted into object containing firstName and lastName as follows:

"responses": {
        "name": {
            "firstName": "John",
            "lastName": "Doe"
        },
        "email": "john.doe@example.com",
        "location": {
            "optionValue": "",
            "value": "Acme Industries"
        }
    }
