Example- Customer has a work order or some other type of document they generate outside of our Salesforce product.
- Customer e-mails work order PDF as an attachment to an e-mail handler.
- Apex then parses through information to get out necessary data and save it or do something with it.
A few possibilities I have thought about-
- Render a blank VisualForce page to run script from e-mail handler. I'm unsure if this is possible to instantiate from an apex class.
