HTTP Request send mail using API

Hi everyone! I’m trying to use HTTP Request to use an API that sends mails, i have never used APIs and i’m so confused in how to use it in UIPATH. Can someone help me?

The API method is POST and the request body is
mailto: “who recives the mail”
subject: “mail’s subject”
mailhtml: “mail’s body in HTML”

You know there are activities that send email, right?

Yes, but in this specific case we need to use an API

Ok just checking.

Which part are you unsure about?
