Pass a report parameter in a URL for a paginated report in Power BI

APPLIES TO:  Power BI service  Power BI Mobile  Power BI Report Builder  Power BI Premium  Power BI Desktop

You can pass report parameters to a report by including them in a paginated report URL. All query parameters can have corresponding report parameters. Therefore, you pass a query parameter to a report by passing the corresponding report parameter. You need to prefix the parameter name with rp: for Power BI to recognize it in the URL.

Report parameters are case-sensitive and use these special characters:

  • A space in the parameter portion of the URL is replaced with a plus sign (+). For example:


  • A semicolon in any portion of the string is replaced with the characters %3A.

Browsers should automatically perform the proper URL encoding. You don't have to encode any of the characters manually.


Parameter examples

To set a report parameter within a URL, use the following syntax:

  • rp:parameter=value

For example, the following URL specifies two parameters, Salesperson and State, defined in a report in My Workspace: 

The following URL specifies the same two parameters defined in a report in an app: 

To pass a null value for a parameter, use the following syntax:

  • parameter:isnull=true

For example:


To pass a Boolean value, use 0 for false and 1 for true. To pass a Float value, include the decimal separator of the server locale.

Additional examples

The following URL example includes a multi-value parameter Salesperson. The format for a multi-value parameter is to repeat the parameter name for each value. 

The following URL example passes a single parameter of SellStartDate with a value of "7/1/2005", for a native mode report server.

Considerations and limitations

  • If your report contains a report parameter that has a default value, and the value of the Prompt property is false (that is, the Prompt User property isn't selected in Report Manager), then you can't pass a value for that report parameter within a URL. This provides administrators with the option of preventing end users from adding or modifying the values of certain report parameters.
  • Power BI doesn't support a query string of more than 2,000 characters. You may inadvertently exceed this value if you use URL parameters to view your paginated report, especially if your query string contains multiple parameter values. To properly load the report, reduce the number of characters to under 2,000.
  • The limit in the query string is evaluated after you sign in to Power BI. If you open the report before signing in, the limit is reduced.
