I m trying to integrate exotel COD app with my magento website which sends a confirmation to the customer when the order is placed. In order to integrate this app it requires a URL which returns http 200 when a order is made successfully or some other code when it fails. I wanted to ask whether magento does something like this on the backend? or how to i write a new script for this ?
You can write a module which implements an observer and listens for the events triggered when an order is placed. You could then send your response like that.
I don't know if this is the best way but it's what came to mind.
