Performing automatic read and update data source from a web data connector

Question

Web data connector URL: http://localhost/datasouceexample/example.html

The data connector holds some data. imports the data from web data connector and then finally create visualizations using the data's from the web data connector URL.

The graph or the visualization was saved in "tableau public" with the embed the code inside my web application. The current visualization is perfect but my question is how can I automate the updating of data
 

1 ) I want to the visualization to be updated automatically based on the value from web data connector URL

2 ) If any new updations are inside input data (new inputs), the visualization should automatically sync with tableau and update the graph, so no changes in the embed code and graph updated automatically

Is there any settings available inside tableau for it? Can someone help me on it?

Answer 1

Dashboard on Tableau Public can only be updated automatically using google sheets. You can redesign your web service to write to write it down to google sheets. Once done you can republish your dashboard to sync with it.
