Can You Redirect a Thank You Page?

Are you able to redirect a thank you page to an external link after X amount of time?

Hi

I hope this link will help you to achieve what you are looking for. 

You can create your own thank you page and add the script to redirect to another page or website with the simple script as mentioned in the link. 

You can also use the following HTML code to redirect from your custom thank you page to another link.

<meta http-equiv="refresh" content="2;url=http://example.com" />

Hope this helps! Please feel free to contact in case you need further help on this.

Any advice how to do this through squarespace? You can't upload html files.

Unfortunately, we do not have much expertise on Squarespace to assist you in this regard. However, as I check on the Internet, I found this link that might be helpful for you. You may check with SquareSpace support so that they can guide you in the right direction.

Thanks!
