Can a backend application access another web service on behalf of another Active Directory user?

Question

Active Directory

Good afternoon,
Imagine that there is a Windows environment, Windows Server, IIS, Active Directory pass-through authorization and all that.
There is some application, let it be in C#, let it be a website.
User1, having logged into Windows, opens this site, on which Windows authorization is installed on the web server, respectively, the same user logged in through the site, now the site knows that user1 came to it.
Now the user presses some button on the site, and the site on the backend makes some http request to another site, or some WebAPI, BUT! you need to make an appeal already on behalf of another user,
more precisely, there is a special service account in Active Directory, the login and password of which the site developer knows, and the developer needs to make it so that when users click on a button, the site backend accesses the WebAPI of some other site, but on behalf of a special account with which there is access to this WebAPI (i.e., when accessing it, WebAPI checks by memberof whether the user can access it at all)
