Locking survey per individual link once completed


I've set up my survey so that my customers recieve an individual link attached to their email address. Is it possible to lock the individual link once the person has submitted? I don't want the individual to forward the link to others.

Hi ​@LLK1990 there’s no feature out of the box that does this within Typeform. However, there is a workaround for preventing duplicate responses (built by ​@picsoung ) which allows you to restrict entries based on email address of the person. This requires use of the API but if you’re comfortable using this it could be an option for what you need: https://medium.com/typeforms-engineering-blog/prevent-duplicate-entries-with-typeform-api-and-serverless-359194d7fa01
