I have a situation here. How to deploy dashboards to server which is not on our network. I mean to publish on to the customer location which is somewhere remotely. The dashboard datasource connections should be changed and get published on to his environment. I have dashboards which has huge data extracts, and data refreshing everyday.For this what could be my approach. working with Document API, REST API or Tabcmds, I have to know the customer server URL? How will the performance of it could be?
