Modifying iframe data of Zoho booking iframe

Modifying iframe data of Zoho booking iframe

Hello,

I have integrated a Zoho Bookings embedded iframe into my website. Currently, I am pre-filling the booking form with default values as part of our process flow. However, I want to ensure that if an input field is already populated with a default value, customers should not be able to edit that specific input box. Our aim is to maintain consistency in the booking process and prevent any unintended modifications.

While Zoho Forms allows disabling field edits, unfortunately, this functionality is not available for input fields within the Zoho Bookings iframe. As a result, I am seeking a solution to achieve the desired outcome of preventing users from making changes to input fields that have already been pre-filled with default data.

Thank you for your assistance.
