Will merge fields work if email is sent through API?

If it works, what is the syntax?

Hi @Mason_Kalashian, yes merge fields are supported on the REST Send an Email endpoint and can be used with this format: ~Contact.FirstName~.

Yes - I tested this the other day - standard format of merge fields work:
~Contact.FirstName~
~Contact.LastName~
~Contact.Phone1~
~Contact.Email~
etc etc
