I'm trying to call an API based on the content of an email. Is that already possible? I understand how to call an API or create a micro service, but it seems like code is triggered when someone sends an email that is esoteric.
For my research, I apparently need an SMTP server and a Pubsub data structure. In the implementations I found on GitHub, they seem to be tailored to send emails rather than trigger code when a user receives an email. I would prefer not to use sengrid or ses aws.
If I need an SMTP server, can I complete it in one semester?
