The Business Central Web client can be deployed as an independent website. In some cases, it's useful to embed parts of the Business Central Web client in other websites, for example, in order to build an internal company portal that not only contains data from Business Central, but also contains news feeds, document handling, and so on.

You can do this by adding an iframe element on the embedding website, such as: <iframe src="https://MyWebServer/BC210/default.aspx?..." />. The Business Central Web client will display the ribbon, the navigation pane, and other UI parts inside the frame. You can update the Business Central Web client to hide the ribbon, the navigation pane, or any UI parts, and only display the core part of the list inside the frame.

Note

Only list pages are supported as framed pages.

Important

Certain data in the URL, such as company name, could be considered sensitive information. Use discretion if you distribute URLs that contain the company name, or if it is possible, exclude this information from the address.

Important

Upcoming releases of some browsers, such as Google Chrome 80 and Microsoft Edge, will include changes to how cookies are handled. To ensure that the embedded web client works with these browser versions, make sure that the Business Central platform has been upgraded to a recommended update version as described in Preparing Dynamics NAV or Dynamics 365 Business Central for Upcoming Changes to Browser Cookie Policy.

Example

The following URL displays page 22 Customers for the CRONUS International Ltd. Company. The page is displayed in a Business Central Web client that is running on a computer that has the name MyWebServer. The page is displayed without the ribbon, the navigation pane, and any UI parts.

https://MyWebServer/business_central_server_instance/?company=CRONUS%20International%20Ltd.&page=22&showribbon=0&shownavigation=0&showuiparts=0

For more information about the page address syntax, see Web Client URL.

iframe Parameters

The following table describes the parameters of the URL for displaying a list page in an iframe.

Parameter	Description
`http\|https`	Specifies the Internet protocol to use. Valid options are `http` and `https`. The `https` protocol helps secure the data that is transmitted over the Internet. To use `https`, Secure Sockets Layer (SSL) must be enabled on the connection to the Business Central Web client. For more information, see Configuring SSL to Secure the Business Central Web Client Connection.
`webserver`	Specifies the name of the computer that is running the Business Central Web client.
`webserverinstance`	Specifies the name of the web server instance for the Business Central Web client. On IIS, this is the alias of the virtual directory of the web server instance. When you install the Business Central Web client using Business Setup, the web server instance is given the same name as the Business Central Server instance that it connects to. If you use the New-NAVWebServerInstance cmdlet to add Business Central Web client instances, then you specify the web server instance name. For more information, see Setting Up Multiple Business Central Web Server Instances.
`default\|blank`	Specifies the name of the active server page file to use to display the page. You can use either of the following types, regardless of the page type: `default, blank`.
`company`	The name of the company in Business Central for which you want to display the page. If you don't select a company, then Business Central Web client uses the company that is defined in the configuration file (navsettings.json). If no company is defined in the configuration file (navsettings.json), then the last company opened by the user is displayed.
`mode`	Specifies the mode in which to display the page. - `View` The page can only be viewed. The user can't change data on the page. - `Edit` The user can change data on the page. - `Create` Opens a blank page that enables the user to create a new item.
`showribbon`	Specifies whether to show the ribbon when the specified page opens. The default value, if the parameter isn't specified, is `1`, which displays the ribbon. Use the value `0` if you don't want to show the ribbon. Important: The `showribbon` parameter can't be used to hide the app bar, use the `isembedded` parameter instead.
`shownavigation`	Specifies whether to show the navigation page when the specified page opens. The default value, if the parameter isn't specified, is `1`, which displays the navigation pane. Use the value `0` if you don't want to show the navigation pane.
`showuiparts`	Specifies whether to show UI parts when the specified page opens. The default value, if the parameter isn't specified, is `1`, which displays the UI parts. Use the value `0` if you don't want to show UI parts.
`isembedded`	Specifies the navigational behavior of the Business Central Web client. If the Business Central Web client is run as part of an external web site, the `isembedded` parameter can be used to specify that the Business Central Web client opens in full screen mode when activated. Use the Back button on the web browser to return from a list. If a card was activated, the original web site is rendered when the card is dismissed. The default value, if the parameter isn't specified, is `0`, which displays the Business Central Web client in a non-embedded manner. Use the value `1` if you want to show the Business Central Web client embedded and in full screen mode, when activated. Important: Specifying the value `1` for `isembedded` will also hide the app bar.
`pagesize`	Specifies the number of lines to display in a grid control, which is useful when embedding the Business Central Web client. The default value, if the parameter isn't specified, is `20`.

Embedding the Web Client in a Website on Another Web Server

By default, the Business Central Web client won't allow a website to display the web client inside an iframe unless the website is hosted on the same web server. This is enforced by having the default value of X-FRAME-OPTIONS set to SAMEORIGIN and Content-Security-Policy to frame-ancestors 'self' in the web.config file.

<httpProtocol>  
      <customHeaders>  
        <!-- SAMEORIGIN: allows framing of the Business Central Web client in another website only if the other website is on the same host. Remove this to enable cross-site framing of the Business Central Web client, but be aware of the increased risk of clickjacking, which could deceive a legitimate user into taking unintended actions on behalf of the attacker. -->  
        <add name="X-FRAME-OPTIONS" value="SAMEORIGIN" />  
      </customHeaders>  
    </httpProtocol>

In order to show a list page in an HTML site on a different host, the configuration file (navsettings.json) of the Business Central Web Server instance that hosts the Business Central Web client has to be configured to include a hostname as a value of the AllowedFrameAncestors setting.

"NAVWebSettings":  {  
    "AllowedFrameAncestors":  "https://myhostname.com",
    ...  
    }
}

Warning

The value of AllowedFrameAncestors accepts wildcards. If you want to specify more hostnames, the values must be separated by commas.

In the following some sample values for AllowedFrameAncestors are shown:

 "AllowedFrameAncestors":  "https://mysite.sharepoint.com,https://yoursite.sharepoint.com",

"AllowedFrameAncestors":  "https://*.myportal.com",

Warning

Be aware that if you remove the <add name="X-FRAME-OPTIONS" value="SAMEORIGIN" /> line from the web.config file, it can pose a potential security risk.

When using Microsoft Entra authentication

This section describes what to do if Business Central is set up to use Microsoft Entra authentication, but the page that hosts the iframe doesn't use Microsoft Entra ID. This section doesn't apply to host pages that use already use Microsoft Entra ID, such as Sharepoint or other Microsoft 365 products.

In this scenario, Business Central won't load inside the iframe until the user has first been authenticated in the parent frame. The reason is that the Microsoft Entra authentication (sign-in) dialog can't load inside the iframe. So, when Business Central tries to redirect to the authentication dialog, and it gets blocked. This isn't a problem for pages hosted in sites that already use Microsoft Entra ID, like Microsoft Sharepoint, because users have been already authenticated to access the page in the first place.

To work around this issue, any custom page that you create to host Business Central in an iframe must authenticate the user in the parent frame, before showing the iframe. There are various solutions to this problem, but the simplest solution is probably to use Microsoft Authentication Library for JavaScript (MSAL.js) for client-side authentication. For more information, see https://github.com/AzureAD/microsoft-authentication-library-for-js/tree/dev/lib/msal-browser. For other ways of doing the authentication, refer to Microsoft identity platform documentation.
