How to add variables to post and mail links

Hey everyone,

I’m trying to add an image with a URL so when readers click on it, they are redirected to a “Thank You” page and then for, we know that’s a “thumbs up”

The challenge comes when I’m trying to implement a custom/dynamic URL that will change thank you parameter. Example: https://beta.whitepaper.mx/thank-you/**?{day}-{month}-{year}**

The {day} should be the post day, {month} month and {year} year.

Do you know any creative way we can achieve this goal? It could be also {uniqueID} or something, we just want to identify which like comes from which posts without creating multiple thank you page/URL shorteners.

Hope I was able to explain correctly.

Thank you
