Project description

Contxt Python SDK


This project requires Python 3.6+.


To install contxt-sdk, just use pip:

$ pip install contxt-sdk

This also installs a command line interface (cli) available via contxt, as long as your active python environment has installed the package. To see the list of supported commands, run the following:

$ contxt -h

Additionally, there is support for command line tab completion via argcomplete. To active, run the following and refresh your bash environment:

$ activate-global-python-argcomplete

Command Line Interface

Getting Started

In order to access any Contxt API, we first need to login. To do so, run the following:

$ contxt auth login

It will prompt you for your username and password, which is the same login you use for your Contxt applications.

Using Machine Authentication (for Workers)

Since the CLI interface is just a wrapper around different functions in the SDK, users can also leverage these functions in their own code. Within Contxt we have a concept of a machine user that is identified by a unique client_id / client_secret pair (instead of a user/pass combination like regular users). When writing code that will eventually go to production that will need to call other APIs (this is obviously quite common), your service will automatically be given a unique client_id / client_secret pair within Contxt. When you create this service, you can use these credentials in your local development environment as well.

Using the Base Worker Class

In order to make development easier, we have a Worker Base Class we provide in the SDK to abstract away the nuance of the authentication process (if you're curious, here is a link to the documentation on this process, in case you're really REALLY bored and looking for some "light" reading). In the root path of this SDK, you'll see an "examples" directory that contains a few example of how to do various tasks. In the file "", you will see a very simple example of how to implement the BaseWorker class.

In this sample worker file, you will see just a few lines of code, to get started. It is vitally important, however, to set your environment variables for CLIENT_ID and CLIENT_SECRET. We provide these in the environment for 2 reasons:

  • You never want to put your client_id / client_secret pair in your code to be committed anywhere. This is a major no-no as these should be regarded the same as user credentials
  • Contxt will automatically set these in the environment upon deployment to a Contxt environment (staging, prod, etc.) so setting this up in development will make it seamless upon deployment
from contxt.workers import BaseWorker

from contxt.functions.facilities import Facilities

class TestWorker(BaseWorker):

    def __init__(self):


        self.facilities = Facilities(auth_module=self.auth_module)

    def doWork(self):

        facilities = self.facilities.get_all_facilities()

if __name__ == '__main__':

    worker = TestWorker()

Looking at the code (pasted above for convenience), you can see that we're implementing the BaseWorker class. Behind the scenes, that class is doing all the work around getting tokens, refreshing tokens, etc. so you don't have to. In this example, we're going to make a call to the Contxt Facilities (Assets) Service to get a list of facilities available to this worker (machine user). To do so, we must instantiate the Facilities class and pass in self.auth_module. In the near future we will remove this parameter to make it easier, but for now, you will always pass in self.auth_module to services.

Next, in the doWork method (you can call this whatever you want, but this is just an example), it's just making a simple call to the facilities function class to get_all_facilities. You can iterate over this list, or just print it to the console (like we've done here).

From here, you can continue to code up your application logic to perform whatever tasks you need using all the SDK functions available to you.

CLI Examples

Exporting IOT Data

You can export field data from the IOT service with the following command:

$ contxt iot field-data -h
usage: contxt iot field-data [-h] [-e END_DATE] [-p]
                             grouping_id start_date {0,60,900,3600}

For example:

$ contxt iot field-data "09d26434-7b5b-448f-911c-2deb5e9a78ce" "2019-02-01" 60

This command will create the directory export_<grouping_slug>_<current_time> with csv files of the associated records each field within the grouping and within the specified time range. There is also a meta.json file which contains specific information about the export like row counts, field ids, and units.
