Hello @jitendrakhatwani
There are 2 ways to do it in WebApp as shown in the image below:
1) Pass the encrypted id in the webapp URL which is available in the email. Then use preloading to get the recipient and map the has clicked field in the Page and make the form auto submit then use storage to update the hasclicked field and the show the thank you page.
2) Use the javascript to get the URL parameter and load the recipient with JS and use xtk session write to update the field.
Thanks,
Manoj
