How to Split Full Name into First Name and Last Name on Public Booking Page?

By default, the Cal ID booking page has a single full name field. Sometimes you'd rather capture first name and last name separately — here's how.

Split the name field

Open the event type, click Edit, and go to the Advanced tab.
In Booking questions, click Edit next to the Your name field.

Toggle Split "Full name" into "First name" and "Last name".

Set the labels and optional placeholders, then click Save.

Click Save at the top right of the event type. The public page now shows separate first- and last-name fields.

Effect on the Booking API

With the name split, the API responses object changes name from a string to an object:

"responses": {
    "name": "John Doe",
    "email": "[email protected]"
}

becomes

"responses": {
    "name": {
        "firstName": "John",
        "lastName": "Doe"
    },
    "email": "[email protected]"
}
