Set user signature with gmail API - How to

Question

Has someone already use gmail API to create signature for a user with apps script ? I've seen this link : "https://developers.google.com/gmail/api/v1/reference/users/settings/sendAs" But I don't know how to use it.

Thanks for your responses JPA

This is possible using the Gmail advanced service: https://developers.google.com/apps-script/advanced/gmail

function setSignature() {
  var newSig = Gmail.newSendAs();
  newSig.signature = "MY NEW SIGNATURE!"
  Gmail.Users.Settings.SendAs.patch(newSig, "me", Session.getActiveUser().getEmail())
}
