Install API Logic Server

Install in Docker or Locally

You can install API Logic Server locally using pip, using Docker, or pythonanywhere (a cloud service).

While pip is a simple install, it requires a Python environment, which is not so simple. We therefore recommend you consider Docker - it's a simpler install, and aligns you with a likely deployment environment.

Create an install directory

You can create this anywhere, such as your home folder or Desktop.

Create an install directory
mkdir ApiLogicServer      # a directory of projects on your local machine
Then, open the appropriate section below, and see the Installation Notes, below.

API Logic Server requires Python 3.11 or higher.

The first section below verifies whether your Python environment is current.

The following section explains how to install a current Python environment.

Verify Pre-reqs: Python 3.11+

Ensure you have these pre-reqs:

Verify 3.11 - 3.12
python --version

python -m venv -h  # also verify these work
python -m pip -h

Note: on Macs, you may need to use python3 instead of python.

If you need to install Python (it can be tricky), see these notes.


Install API Logic Server in a virtual environment

Then, install API Logic Server in the usual manner:

Install API Logic Server in a Virtual Environment
cd ApiLogicServer                    # directory of your choice
python -m venv venv                  # may require python3 -m venv venv
source venv/bin/activate             # windows venv\Scripts\activate
python -m pip install ApiLogicServer

If you are using SqlServer, you also need to install pyodbc.

Start (might install) API Logic Server Docker
cd ApiLogicServer      # a directory of projects on local host

# Start (install if required) the API Logic Server docker container...

docker run -it --name api_logic_server --rm -p 5656:5656 -p 5002:5002 -v ${PWD}:/localhost apilogicserver/api_logic_server

This will start a command line in the Docker container at your current directory. You are now able to issue commands like ApiLogicServer create as described in the home page. These will create API Logic Projects as directories under your current directory.

Windows: use Powershell (PWD is not supported in Command Line)

API Logic Projects are not restricted to be under the same directory.

The api_logic_server image supports startup arguments so you can control the api_logic_server container, by running a startup script or by supplying environment variables. You might, for example, have automated test procedures that load projects from GitHub and run tests.

For more information, see Working With Docker.

Already installed? Upgrade to the latest: docker pull apilogicserver/api_logic_server (you may need to rebuild your container).

You can create an ApiLogicServer on PythonAnywhere for any cloud-accessible database.  Open a bash console, and:

python3 -m venv venv  # ensures that Python3 is used  
source venv/bin/activate

python3 -m pip install ApiLogicServer

ApiLogicServer create --port=   # ApiLogicServer == your account  

1. Create Application

Here is an example using a pythonanywhere-hosted MySQL database (note the escape character for the $ in the database name):

ApiLogicServer create --project_name=Chinook \ --port= \

2. Create and configure a web app


3. Update the wsgi And copy the contents of /home/ApiLogicServer/api_logic_server/ over the wsgi file created by pythonanywhere.

4. Update the Admin App api_root The first few lines of the Admin.yaml and Admin Config page should be (update the last line:

  date: December 26, 2021 09:00:00
  recent_changes: altered tab captions
  version: 3.50.51

5. Verify admin.yaml Verify that the ui/admin.yaml ends with something like this:

  max_list_columns: 8
6. Configure the host and port

In, set these as follows:

host = ""  # was "localhost"
port = ""                                   # was "5656"
7. Restart the Web App You start ApiLogicServer from the web console, not from the command line

8. Run the application

You can open the Admin App in your browser

You can use curl from pythonanywhere consoles:

curl -X GET "" -H  "accept: application/vnd.api+json" -H  "Content-Type: application/vnd.api+json"  


Installation Notes

Alert - Project fails to start

Recent updates to included libs have broken previous versions of API Logic Server. This is fixed in a new version (5.00.06), and is strongly recommended. You can also repair broken installations as described in Troubleshooting.

Heads up - Certificate Issues

We sometimes see Python / Flask AppBuilder Certificate issues - see Troubleshooting.

Default Python version

In some cases, your computer may have multiple Python versions, such as python3. ApiLogicServer run relies on the default Python being 3.8 or higher. You can resolve this by: * making python3 the default Python, or * using ApiLogicServer create, and running python3


Next Steps - Create a Project

Create, start and debug the sample project - see the Creating a Project.
