How to pull text from URL into a single line in a Zoho Form

How to pull text from URL into a single line in a Zoho Form

I managed to add a unique identifier at the end of my form's link, but i need this identifier to be populated inside the actual form in order for my zap in zapier to be able to detect it and use it for the following steps in my automation. Is there somewhere i can add coding into zoho forms through the builder? Im not an expert in coding but if theres an area I can add some java or python i can definitely find my way around making it happen. Please let me know if you have any ideas or sugestions on how to achieve this.
