Prepopulate by URL

Hey community,

i’m using contactform7 and tried to find a way to prepopulate / prefill this contactform by using a “static link” send by email.

example: Costumer is buying bananas and wants to send a request via contactform. I would like to send a link he can click on that prefills name, customer id, product name, product id, topic, … without havin the user to log in.

i spend days searching for a solution, but i couldn’t find one. (And yes, pre-setup email “link” via HTML is no option – it has to be done via contactform.)

can you pls help me with that? or – if not possible – do you know any other product, that can manage something like that?
