I want to be able to send a shipment email through Acumatica (using an Email Template) from a non-Acumatica Web application. I can't use a Change Notification because it needs to be entirely manual. I've pored through questions here and the documentation but can't figure it out—I'm sure I'm missing something.
Is there a way to do it through the REST API?
We are on Acumatica 6.10.1219.
