Automatically Invoking Import Template

Is it possible to automatically invoke an import template?

Currently, we have a web form built in Laravel (PHP) that our staff fill in - specifically they create new suppliers this way. This form produces a CSV file in Sage format when filled in which gets placed in the import folder. 

We are looking at the possibility of automating the whole process - i.e. having Sage automatically import the CSV file when it has been produced.

Is there any way of doing this from PHP possibly by sending a GET/POST request to Sage to invoke an import sequence that we have, after the CSV has been created?
