Form submit based on parameter in URL?

Hello,

I have this situation:

Form #1 filled and submitted by an admin with a client's info. The form #1 creates a custom post and sends notification to client's email address. In that notification there's a confirmation link with parameters in the URL (Based on those parameter I change some values for the custom post, not important as the moment, I've already figured out how to do that). So next step is when the client clicks the confirmation URL, they open a page - "thank you for your confirmation".

On the "thank you for confirmation" I'm planning to have a second form, let's name it form#2, that will get the parameters in the URL.

Is it possible to have form #2 submitted automatically based on parameter in the URL?

Kind regards,
Mihai

It will be submitted automatically but always conditioned by a specific parameter in the URL.

Thanks Chris for the info, I'll test it.
