Accessing Business Central from the Business Central Web client or App requires a Business Central Web Server instance on Internet Information Services (IIS). You create a Business Central Web Server instance for the Business Central Web Server two ways:

Using the Business Central Setup to install the Business Central Web Server
Running the New-NAVWebServerInstance cmdlet.

When you set up a web server instance, you're configuring the connection to the Business Central Server instance. The connection settings are saved in a configuration file for the web server instance.

About the configuration file

The configuration file for the web server instances is a .json file type called navsettings.json. The navsettings.json file is a JavaScript Object Notification file type that is similar to files that use the XML file format.

After installation, you can change the configuration by modifying the navsettings.json. There are two ways to modify this file: directly or using PowerShell.

Where to find the navsettings.json file

The navsettings.json file is in the physical path of the web server instance. By default, the path is C:\inetpub\wwwroot\[WebServerInstanceName] on the computer's hard drive.

[WebServerInstanceName] corresponds to the name (alias) of the web server instance in IIS, for example, C:\inetpub\wwwroot\BC210.

Modify the navsettings.json file directly

Open the navsettings.json in any text or code editor, such as Notepad or Visual Studio Code.

Each setting is defined by a key-value pair.

In the navsettings.json file, a setting has the format:
```
"keyname": "keyvalue",
```
The keyname is the name of the configuration setting and the keyvalue is the value.

For example, the configuration setting that specifies the Windows credential type for authenticating users is:
```
"ClientServicesCredentialType":  "Windows",
```
Include values in double quotes.
Find the configuration settings that you want to change, and then change the values.

Refer to the Settings section for a description of each setting.
When you're done making changes, save the file.
Restart the Business Central Web Server instance for the changes to take effect.

For example, in IIS Manager, in the Connections pane, select website node for Business Central Web Server, and then in the Actions pane, choose Restart. Or, from your desktop, run iisreset.

Modify the navsettings.json file by using the Set-NAVWebServerInstanceConfiguration cmdlet

The PowerShell script module NAVWebClientManagement.psm1 includes the Set-NAVWebServerInstanceConfiguration cmdlet that enables you to configure a web server instance.

Depending on your installation, run the Dynamics NAV Development Shell or Windows PowerShell as an administrator.

Learn more in Get started with the Business Central Web Server cmdlets.
For each setting that you want to change, at the command prompt, run the following command:
```
Set-NAVWebServerInstanceConfiguration -WebServerInstance [MyBCWebServerInstance] -KeyName [Setting] -KeyValue [Value] -SiteDeploymentType [Type]
```
Replace:
- [MyBCWebServerInstance]with the name of the web server instance for the Business Central Web Server.
- [Setting] with the name of the setting. Refer to the next section in this article.
- [Value] with the new value of the setting.
- [Type] with the site deployment type either SubSite or RootSite.
  
  Note
  
  Although -SiteDeploymentType isn't a required parameter, the PowerShell script module NAVWebClientManagement.psm1 is written such that the default value for SiteDeploymentType is SubSite. If SiteDeploymentType isn't provided, the cmdlet will only operate against subsites.

Settings in the navsettings.json

The navsettings.json has the following structure, where settings are included under one of two root elements: NAVWebSettings and ApplicationIdSettings:

{
  "NAVWebSettings": {
     "//ServerInstance":  "Name of the Business Central Server instance to connect to (for client) or listen on (for server).",
     "ServerInstance":  "BC150",
      [...more keys]
 },
  "ApplicationIdSettings": {
      "BlogLink": "https://myBCBlog.com",
      [...more keys]
  }
}

// indicates a comment that provides help for the setting, and has no effect on the Web Server instance.

The following table describes the settings that are available in the navsettings.json for each root element.

If you don't see a setting in the file, it's because some settings aren't automatically included as a key in the file. For these settings, you can add the key manually.
If you don't add the key, the default value of the setting is used.

Important

If modifying the file directly, place values in double quotes "".

For more information, see Using security certificates with Business Central on-premises. Default value: false
ServicePrincipalNameRequired	If this parameter is set to `true`, then the Business Central Web Server can only connect to a Business Central Server instance associated with a service principal name (SPN). If this parameter is set to `false`, then the Business Central Web Server attempts to connect to the configured Business Central Server service, even if the service isn't associated with a service principal name (SPN). For more information about SPNs, see Configure Delegation. Default: `false`
SessionTimeout	Specifies the maximum time that a connection between the Business Central Web Server and the Business Central Server can remain idle before the session is stopped. In the Business Central Web Server, this setting determines how long an open Business Central page or report can remain inactive before it closes. For example, suppose the SessionTimeout is set to 20 minutes. If a user doesn't take any action on a page within 20 minutes, then the page closes and the following message appears: The page has expired and the content cannot be displayed. The time span has the format [dd.]hh:mm:ss[.ff]: - dd is the number of days - hh is the number of hours - mm is the number of minutes - ss is the number of seconds - ff is fractions of a second Default value: 00:20:00

Default value: `true`
UnknownSpnHint	Specifies whether to use a server principal name when establishing the connection between the Business Central Web Server server and Business Central Server. This setting is used to authenticate the Business Central Server, and it prevents the Business Central Web Server server from restarting when it connects to Business Central Server for the first time. You set values that are based on the value of the ServicePrincipalNameRequired key. Value: The value has the following format. (net.tcp://BCServer:Port/ServerInstance/Service)=NoSpn\|SPN - `BCServer` is the name of the computer that is running the Business Central Server. - Port is the port number on which the Business Central Server is running. - ServerInstance is the name of the Business Central Server instance. - NoSpn\|SPN specifies whether to use an SPN. If the ServicePrincipalNameRequired key is set to `false`, then set this value to NoSpn. If the ServicePrincipalNameRequired key is set to `true`, then set this value to `Spn`. Default value: (net.tcp://localhost:7046/BC210/Service)=NoSpn If you set this key to the incorrect value, then during startup, the Business Central Web Server automatically determines a correct value. An incorrect value causes the Business Central Web Server to restart. Note: For most installations, you don't have to change this value. Unlike the Dynamics NAV Client connected to Business Central, this setting isn't updated automatically. If you want to change the default value, then you must change it manually. APPLIES TO: Business Central 2022 release wave 1 (version 20) and earlier.
UseAdditionalSearchTerms	Specifies whether Tell me uses the other search terms that are defined on pages and reports. The other search terms are specified by the AdditionalSearchTerms and AdditionalSearchTermsML properties. If you set this key name to `false`, the other search terms are ignored. Default value: true
SaveValueToDatabasePromptly	If set to `true`, changes to values in fields are saved to the database as soon as the user moves focus from the field, for example, by selecting `Tab`. `false` is the default value. If set to `false`, changes aren't saved until the user closes the page by using the back arrow or stops editing by choosing the edit (pencil) button. After a user makes changes to a field and moves focus to the next field, the status in the upper-right corner of the page changes to Saving and then to Saved. This behavior can be misleading because the changes aren't yet saved to the database at this time.
