I found an undocumented flag skip_email that prevents the email being sent so you can just grab the link. Pass it in the body with the email and you should be good!
{
"email": "someone@test.com",
"skip_email": "true"
}
I did some brief testing and it’s worth noting that if you use it to generate an email link, then you can’t go back and use it to send an email automatically - emailed always returns false once skip_email is used.
