Isah Finance Web Services

Please note: You need to install WebDAV before proceeding with the installation of the Isah Finance Web Services.

For security reasons, Isah recommends that you acquire a certificate for your website to encrypt your transactions.

1. Start Isah.Service.Finance.Setup.msi to install the Isah Web Services.
2. If you already have an installation of the Isah Web Services, it is possible to add another instance (or more), for example for test purposes. In the first window, specify if you want to install a new instance or upgrade an existing instance.

   Note: You can only use letters, numbers, spaces and underscores when you specify an instance name.

3. Follow instructions and press Next when necessary.
4. In the IIS Application Pool window, specify the Windows user that will access and run the web services. There are several built-in user accounts with varying permissions. The standard account is ApplicationPoolIdentity.

   If you want to use a custom account, you will need to verify its credentials before you can continue the installation process.

   Information on Windows users

   • ApplicationPoolIdentity: This is a dedicated user account for the working process of the application pool.
   • LocalService: This account has the same user rights as the Network Service account, but it is limited to the local computer.
   • LocalSystem: This account has all user permissions. It is part of the Administrators group on the web server.
   • NetworkService: This account is a member of the Users group and has permission to run applications.
5. The installation will ask you to enter the database connection details:

   SQL instance

   Enter your SQL server name and instance name.

   Trusted (Windows Authentication) / Specify username and password

   Trusted (Windows Authentication)

   If you want to use the Windows Authentication, click Trusted. The installer will use the account you entered for the Application Pool; this user needs to have the IsahFinanceRole on the database you will use. Assign it to your application pool user if necessary. Please note:

   • If your trusted user is the ApplicationPoolIdentity and the Isah Finance Service is being installed on the database server (which is not recommended), you need to assign permissions to user IIS Appool\Isah AppPool x, in which x is the Isah Finance Service number in the name of the installation.
   • If your trusted user is the ApplicationPoolIdentity and the Isah Finance Service is being installed on another server, user {DOMAINNAME\COMPUTERNAME$} - for instance {ISAH\C0258$} - needs permissions for the database.

   You will not need to enter a login and password and can proceed with Next.

   Specify username and password

   If you want to specify another user name, click Specify username and password:

   • Login: This must be a user with both the IsahWebServicesRole and IsahElectronicReturnsRole in the Isah database. Use SQL Server Management Studio to assign this role to the SQL Server user in the Isah database. Isah recommends a user name with IsahFinanceRole permissions only. These are the only permissions required to run the Isah Finance Service.

     Isah does not recommend the use of SQL user 'sa'.

   • Verify connection: ensure the connection works properly by pressing this button. After the connection has been verified, the Next button becomes active.
6. Test environment: activate this field to create a test environment (e.g. for sending messages like VAT returns to the preproduction environment of Digipoort instead of the Digipoort production environment). If this setting is active when you install Isah Web Services, Isah Finance will show that you are working in a test environment.
7. In the Database window, enter the database name and verify the connection if necessary (you will not need to verify the connection if you have chosen Windows authentication in the previous window). If the user you entered in the previous window does not have sufficient permission, a message to that effect will appear. In that case, to avoid installation problems, it is better to go back and enter a user name with IsahWebServicesRole in the Isah database.
8. The WebDAV Server Connection window concerns the accessibility of documents.
   • Enter the address of the server that hosts the WebDAV website, for instance localhost or 192.168.1.140.
   • Enter the Port you specified when installing WebDAV.
   • Enter a username and password. This user needs to have the correct Windows permissions for the WebDAV website and the directory that holds your documents.
9. Click Verify credentials.
10. Enter a website name for the Isah Finance Web Services and the port number the services will use.

    For security reasons, Isah recommends that you acquire a certificate for your website to encrypt your transactions. If you choose not to use a certificate, select Use HTTP. If you have a certificate, select the HTTPS connection type and select your certificate in the next window.

11. Enter the Electronic Returns Windows Service port.
12. Enter the license server host and license server port.
13. Enter the destination folder.
14. Press Install.

Note: The Isah Finance Electronic Returns Service is installed to run as the built-in ‘Local System’ user. Please do not change this.
