Populating Data into external website and Click on some buttons and then redirect the user to that website with the information filled in and let them do some actions there. My problem is I want the user to be able to fill a form on my web page and fill that information to an external website and click on a button and then let the user do some actions to the external website. And the external website does not allow get request.

I tried using puppeteer but its on the backend - so how will the user access it. Any help will be appreciated.
