Check permissions API

As a developer of Power BI visuals, you can develop visuals that need permission to access various resources. You request these permissions in the privileges section of the capabilities.json file. These privileges include the ability to access:

• remote resources or web sites
• local storage for downloading data

Each organization's admin can allow or block these permissions. The check permissions API allows you to query the host at runtime to determine which permissions are granted. You can use this information to design a visual that will work with various permission settings.

The check permissions API returns the status of each permission query function:

/**
 * Represents a return type for privilege status query methods
 */
export const enum PrivilegeStatus {
    /**
     * The privilege is allowed in the current environment
     */
    Allowed,

    /**
     * The privilege declaration is missing in visual capabilities section
     */
    NotDeclared,

    /**
     * The privilege is not supported in the current environment
     */
    NotSupported,

    /**
     * The privilege usage was denied by tenant administrator
     */
    DisabledByAdmin,
}

How to use the check permissions API

Every privilege API has its own query method to check for the permission status. The permission status can be one of the following:

• Allowed
• Not declared
• Not supported
• Disabled by Admin

Web access

export interface IWebAccessService {
    /**
     * Returns the availability status of the service for specified url.
     * 
     * @param url - the URL to check status for
     * @returns the promise that resolves to privilege status of the service
     */
    webAccessStatus(url: string): IPromise<PrivilegeStatus>;
}

Export content

export interface IDownloadService {
    /**
     * Returns the availability status of the service.
     * 
     * @returns the promise that resolves to privilege status of the service
     */
    exportStatus(): IPromise<PrivilegeStatus>;
}
