I am a G-suite admin and i have 45 users in my company. I want to be able to add the 45 users signatures automatically and not let everyone add it by themselves in order to unify it. So I need to create a gmail api in order to be able to do that.
I want the signature to have the logo, full name of the user, job title, OU where the user is located, Phone number. fax, email, website, facebook and linkedin logos plus links.
