The APP service plan should meet these requirements

Step 1 – CREATE AZURE WEB APP

1. In the Azure portal, select App Services – Create – Web App.
2. Choose your subscription and the appropriate resource group.
3. Give the web app a name.
4. Under Publish, select Code.
5. Runtime stack is .NET 8 (LTS) (viflow subscription and viflow 9) as of June 12, 2025.
6. Operating system is Windows.
7. Region choose the one that suits you best (Germany is Germany West Central)
8. Create the web app via Review + Create
9. Now open the web app via Home – Web app name.
10. Open the configuration. 
11. Under Platform , select 64 Bit.
12. To enable upload with an FTP tool (WinSCP, FileZilla, etc.).
    • Enable credentials for SCM basic authentication publishing
    • Activate FTP Basic Authentication Publishing Credentials 

Step 2 – RESTRICTING ACCESS TO YOUR OWN DOMAIN (NO LOGIN TO THE WEB MODEL)

1. By default, anyone who knows the web app's address can access it. To restrict access to your own domain, proceed as follows:
   • Open the Azure portal and select the web app.
   • Now navigate to Authentication.
     • Click Add Identity Provider.
     • Identity provider: Microsoft (the current tenant is selected by default)
     • Normally, all you need to do now is set the lifetime of the client key under Client Secret Expiration.
     • Click Add to complete the setup.

Step 3 – EXPORT WEB MODEL AND UPLOAD WITH FTP TOOL (HERE: WINSCP)

1. Export a WebModel with authentication disabled. 
2. Open your Azure Web App overview in the Azure Portal.
3. Navigate to Deployment – Deployment Center.
4. Click the FTPS Login Information tab.
5. Open the FTP tool of your choice and configure it as follows:
   • Transfer protocol: FTP
   • Encryption Explicits: TLS/SSL
   • Server address: the FTPS endpoint from the portal
   • Port number: 21
   • Username: the FTPS username from the portal under Application area
   • Password: the password from the portal under Application area
6. Once the connection is established successfully, the entire contents of the WebModel folder must be uploaded.

Troubleshooting – What should I consider?

1. Save customized appsettings.json file
   • To include the customized appsettings.jsonin the export and to prevent it from being overwritten, it must be stored in the following folder:
     • Open the folder %USERPROFILE%\Documents\viflow
     • Create the Customizations folder and open it
     • Create the folder WebApp , open it and place the customized appsettings.json in it (the path to the appsettings.json should then look like this: %USERPROFILE%\Documents\viflow\Customizations\WebApp
       
       
2. Update the client secret
   • The client secret you created in step 2 must be recreated after a certain period of time. 
     
     
3. WebApp logs
   • If our support requests the web server event log messages, you can find them in the Azure Portal at:
     Web app name – Diagnostics and troubleshooting – Diagnostic Tools – Application Event Logs.
