Rendering a Report Using URL Access
You can run a report using URL access by specifying the Command parameter with a value of Render. You must use the parameter prefix rs: with this parameter. This renders the specified report in the default rendering format for the browser you are using to access the report server. Using the Render value for the Command parameter equates to calling the Render method in the Report Server Web service. For more information about the Command parameter, see Using the Command Parameter.
Note
If you omit rs:Command=Render from the URL string, the report is rendered by default. For more information, see Using a URL to Access Report Server Items
Example
The following example uses the Command parameter to render the specified report:
https://servername/reportserver?/Sales/YearlySalesByCategory&rs:Command=Render
