TN Delivery Service for FTTPS-Need to set file name

I have a new requirement to deliver flat files via FTPS to several partners. Looking at documentation for the build in service, the file name is set to the internal doc id. I want to be able to specify the file name. I presume I will have to write my own custom service. Has anyone done this already? Any sample code or advice?

You’ll need to create your own service. I’d recommend a custom delivery service and register it with TN. Doing so is pretty straight-forward.
