Connect Resend and send an email from an API or an event trigger.

TEMPLATE AVAILABLE

If you wish to skip the manual setup, there is a workflow template available called Send Notification Email w/Resend. You can find it inside the templates available when creating an API workflow.

START WITH WEWEB FOR MOST AUTH EMAILS

If you only need email verification emails, password reset emails, magic links, or OTP emails, start with WeWeb's built-in backend Send Email action instead.
