I'm trying to figure out how to add a customer email to my customer base (no account, name, etc., just the email) as if it were a newsletter signup, through the admin api. I can gather that this isn't possible as a post request to /customers, as documentation requires a first and last name.
I want to collect email addresses as part of a custom signup flow, and then later I want to use that email to create an active customer account. this is a separate topic and issue altogether.
Anyone have any advice?
