How to configure and run Workflow Server

General information

Workflow Server is a ready-to-use Workflow Engine-based application that you can deploy into your infrastructure. It can be integrated with NodeJS, PHP, Ruby, .NET, or Java applications via an HTTP API. Workflow Server is a key component which manages the lifecycle of business objects within your enterprise.

Initially, download from this page and extract it. Where version is the Workflow Server version number. Or you can clone the GitHub repository.

How to launch via GitHub

  1. Clone the repository.

    git clone
    cd WorkflowServer
  2. Next, you can follow the instructions below for launching the Docker container.




    chmod +x docker-files/
    chmod +x

How to launch via Docker


You need Docker with the Docker Compose plugin.

  1. Run the startcontainer script.
  • For Windows: run the file: startcontainer.bat

  • For Linux/MacOS:

    chmod +x docker-files/
    chmod +x

    This script build this Workflow Server's solution and run it with PostgreSQL database.

  1. Open http://localhost:8077 in a browser.
  2. Upload your license key via the Dashboard or save the licence key as license.key into the folder or add to 'license' folder.
  3. Fill out the Callback API urls at http://localhost:8077/?apanel=callbackapi to perform integration.

In case of running Workflow Server on MS SQL or MongoDB, then you can use these docker-compose files:

  • MS SQL Server: docker-files/docker-compose-mssql.yml
  • MongoDB: docker-files/docker-compose-mongo.yml

MongoDB script:

chmod +x docker-files/
docker compose -f docker-files/docker-compose-mongo.yml build
docker compose -f docker-files/docker-compose-mongo.yml run --rm start_db
docker compose -f docker-files/docker-compose-mongo.yml up

MS SQL script:

chmod +x docker-files/
docker compose -f docker-files/docker-compose-mssql.yml build
docker compose -f docker-files/docker-compose-mssql.yml run --rm start_db
docker compose -f docker-files/docker-compose-mssql.yml up

How to launch it with a custom database

  1. First, the following SQL-scripts should be run from the SQL\MSSQL directory if you use MS SQL Server Database:

    • CreatePersistenceObjects.sql.
    • WorkflowServerScripts.sql.

    You might run also the scripts for PostgreSQL from SQL\PostgreSQL directory, Oracle in SQL\Oracle, and MySQL Database from SQL\MySql.

  2. Make the following changes to the config.json file:

    • Change the URL parameter to the IP and the port of the HTTP listener. Most likely you'll need to leave it as is.
    • Specify "mssql", "postgresql", "oracle", "mysql" or "mongodb" in the Provider parameter depending on what database provider you are using.
    • Change the ConnectionString parameter to match your database provider connection settings.
"Provider": "mssql",
"ConnectionString": "Data Source=(local);Initial Catalog=WorkflowServer;Integrated Security=False;User ID=sa;Password=1;TrustServerCertificate=True;"
  1. Install .NET 8.0 (use Arm64 instead of x64 for Apple M chips).

  2. Run the Workflow Server:

    • Workflow Server supports console and service modes on Windows:
      • Run the start.bat file to run it in the console mode.
      • Run the installservice.bat as administrator to run it in the service mode.
    • For Linux/MacOS:
      • Open the terminal in the directory where was extracted the archive.
      • Run the following commands:
        chmod +x
  3. Open http://localhost:8077 in a browser.

  4. Upload your license key via the Dashboard or save the licence key as license.key into the folder or add to 'license' folder.

  5. Fill out the Callback API urls at http://localhost:8077/?apanel=callbackapi to perform integration.

How to rebuild Docker image


Your database port must be accessible via the Docker network.

  1. Edit the config.json file as described here.

  2. Run the command from the project root folder:

    docker build --tag my-workflow-server --file WorkflowServer/Dockerfile .
  3. Run the Docker container:

    docker run my-workflow-server

How to rebuild and run

  • For Windows:

  • For Linux/MacOS:

    chmod +x
    chmod +x

How to run in Visual Studio

  1. Open WorkflowServer.sln in Visual Studio or JetBrains Rider.
  2. Check the connection string to the database in the config.json file, Provider and ConnectionString parameter.
  3. Run WorkflowServer project.

How to completely customize Workflow Server

  1. Open WorkflowServer.sln in Visual Studio or JetBrains Rider.
  2. The solution contains only one project, WorkflowServer; you can add references to your own projects and dlls to it.
  3. In the WorkflowServer project, find the Program.cs file; you can optionally configure WorkflowRuntime here.


Program.cs contains the following code:

(bool success, IWebHost host) = initializer.BuildWebHost(workflowServer =>
//Register your own Action and Rule providers
//workflowServer.RegisterActionProvider(new ActionProvider());
//workflowServer.RegisterRuleProvider(new RuleProvider());

//Register your own CodeAutocompleter
//workflowServer.RegisterCodeAutocompleters(new CodeProvider());

//Register your own Identity Providers:
//workflowServer.RegisterOpenIdConnectProviders(authBuilder =>
// authBuilder.AddOpenIdConnect("authenticationScheme", "display name", options =>
// {
// // ...
// //options.SignInScheme = IdentityServer4.IdentityServerConstants.ExternalCookieAuthenticationScheme;
// });

//register additional assemblies
}, webHostBuilder =>
webHostBuilder.ConfigureServices(services =>
// register your own services in a DI container (available from Workflow Server 5.0.0 version)

// register your custom activity from DI container
var workflowServer = host.Services.GetService<WorkflowServerRuntime>();
var customActivity = host.Services.GetService<CustomActivity>();

The object workflowServer.WorkflowRuntime is available here; thus, you can add your own versions of:

Therefore, you get access for complete customization of Workflow Engine in Workflow Server.
