Dynamic URL with timestamp, MD5 hash

Hi there – I am hoping to solicit ideas on how I may go about achieving a dynamic URL, that when a user clicks on it, it will insert a few variables described below.

The url will be https://example.com/login?variable1=STATIC&timestamp=YYYYMMDDHHMMSS&hash=DYNAMICHASH

variable1 is a static number (in this example 12345).
timestamp variable needs to be the date and time in the format YYYYMMDDHHMMSS.
hash variable needs to be a MD5 hash of variable1 + timestamp + shared secret

So the final URL would be: https://example.com/login?variable1=12345&timestampe=20200716141823&hash=84f7dd3d73748273384d837d84ss34

Any guidance would be much appreciated.
