Get data from Creatio to a Landing page (Auto-fetch)

Hello Everyone,

I want to implement a functionality on a web page where a Phone Number field is used to retrieve customer data. When a phone number is entered and submitted:

1. If a matching customer record exists in Creatio, the page should automatically populate with the customer’s details.
2. If no record is found, a new customer record should be created in Creatio.
3.  

Is this functionality achievable? Any guidance would be appreciated!

Thanks in advance.
