threema.gateway 3.1.0

An API for the Threema gateway service to send and receive messages including text, images, files and delivery reports.

threema-gateway is a Python 3 module for the Threema gateway service. This API can be used to send and receive text messages to and from any Threema user.

Note

On machines where Python 3 is not the default Python runtime, you should use pip3 instead of pip.

Prerequisites

$ sudo apt-get install python3 python3-pip

We recommend using venv to create an isolated Python environment:

$ pyvenv venv

You can switch into the created virtual environment venv by running this command:

$ source venv/bin/activate

While the virtual environment is active, all packages installed using pip will be installed into this environment.

To deactivate the virtual environment, just run:

$ deactivate

If you want easier handling of your virtualenvs, you might also want to take a look at virtualenvwrapper.

Installation

If you are using a virtual environment, activate it first.

Install the module by running:

$ pip install threema.gateway

The dependency libnacl will be installed automatically. However, you may need to install libsodium for libnacl to work.

Command Line Usage

The script threema-gateway provides a command line interface for the Threema gateway. Run the following command to see usage information:

$ threema-gateway --help

Examples

You can find a few example scripts in the examples/ directory.

Note that most of them need to be adjusted to at least add your gateway ID credentials before they run successfully.

Feature Levels

Level	Text	Capabilities	Image	File	Credits
1	X
2	X	X	X	X
3	X	X	X	X	X

You can see the implemented feature level by invoking the following command:

$ threema-gateway version

Callback Server

The callback server can be used to receive messages. The demo script threema-callback-server prints out received message on the command line. Run the following command to see usage information.

$ threema-callback-server --help

The script resides here.

Troubleshooting

Invalid environment marker: python_version<=”3.4”

If you’re getting the following error when installing the library:

Unpacking /tmp/threema-msgapi-sdk-python
  Running setup.py (path:/tmp/pip-5b1d7h0w-build/setup.py) egg_info for package from file:///tmp/threema-msgapi-sdk-python
    error in threema.gateway setup command: Invalid environment marker: python_version<="3.4"
    Complete output from command python setup.py egg_info:
    error in threema.gateway setup command: Invalid environment marker: python_version<="3.4"

… then you have an old version of setuptools installed. If you use a venv (as described in the “Prerequisites” section), enter it (using source venv/bin/activate) and then upgrade setuptools:

$ pip install -U setuptools

Now installing the threema.gateway module should work.
