Hi All 

I am building a reporting dashboard and need to have the OS platform collect/retrieve an excel sheet as well as other CSVs from a secure location (not on my local machine). 

I have all the credentials I need but the location, where the data files are stored, doesn't have any function that can push these files or its data to the OS platform. 

I was told I need to build a web service to collect the file on the scheduled bases. Is anyone aware of a service that may have already been created for this very purpose?    

Is there any reason you want to do this via webservice?  Is FTP available? There are multiple FTP components on the forge that could do the file retrieval for you.
