One-to-one email API

Is it possible to send one-to-one email using API ?

Hi @AIlin! Welcome to the Community-- happy to have you here :blush:

We can use the Engagements API to log emails to an object record, but it doesn’t offer an endpoint for sending 1–1 emails. @jackcoldrick discusses Transactional email sends as well in this thread. That said, note that transactional emails are not fit for Sales correspondence.

Best,

Hi,
I would also suggest that you have a look at the Transactional Email API endpoint
