Threema Gateway API

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

Gateway API Endpoint

The default Gateway API Endpoint URL used is https://msgapi.threema.ch/.

If you are a Threema OnPrem customer or have another reason to use a different Gateway API Endpoint, you may override the URL as follows:

$ export GATEWAY_API_URL=https://onprem.myinstance.tld/msgapi

Any following calls to threema-gateway will then use the supplied Gateway API Endpoint URL.

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.
