I'm new in Saleforce development and would like to ask for a direction. Salesforce provides good platofrm for fast creation of web applications. But what if I need to create a headless application. For example, I'd like to take records of Opportunities or any custom object, then to do some non-trivial manipulations and create new records for another object.
- Where shoudl I start?
- how to host such application: I'd like to avoid taking export data from Salesforce and put data into saleforce from outside (do not host custom developed solution on AWS)
