Alberta MOT

Fetching data from Alberta MOT with Airbyte and Python.


This Airbyte Connector uses the HTTP API provided by the Alberta MOT in Python. With this connector, data is easily pulled from Alberta MOT and loaded into the ViaWarn Postgres database, and are available in the ViaWarn app.

The connector is built on top of the Airbyte open-source platform, which provides a standardized way of integrating data sources and destinations. It is designed to be simple and easy to use. The required configuration is show in the the sections below. 

The pulled resources from the Alberta 511 API are the following:

Requirements and Installation

Find the requirements and steps to create the connector in the Airbyte documentation.

Customized files

After creating the Airbyte connector template, modify the next files to retrieve data from Alberta MOT .


Location: source-viawarn-ca-al-abt/spec.yaml
Access API: FREE
In this case, the connector password is specified in the spec file.
  title: VIAWARN CAN AB ABT - Spec
  type: object



Location: secrets/config.json
This file is ignore by git.
The config file holds an empty directory because this API is FREE and does not require any other parameter.


Location: integration_tests/configure_catalog.json
List of Streams that describes the data in the data store that a Source represents. It also declares the sync modes supported by each stream (full refresh or incremental).

Declare schemas for each stream by adding json files. Each file is a JsonSchema describing the output from that stream.

class ViawarnCaAbAbtStream()

Create a stream to represent the data that will be pull from the API. It contains all the common API functionalities:
  •  url_base

This field is the common part of the URL for all streams, if it does not exist, add it in each stream method.


  • next_page_token()

Pagination is not provided by this API.

return None

  • parse_response()

It is a placeholder to store the request.response object and constructs the appropriate mapping object for each parsed element by each Stream class.

yields an empty dictionary.

class Cond()

This method extends the ViawarnCaAbAbtStream() method to specified unique behavior for this stream.
  • primary_key

Unique field required in the stream associate to each output record.


  • path()

subdomain to be passed into the URL.

return a string

  • parse_response()

Definition of how a response is parsed.

Set a definition to: primary key and ewkt fields.

return an iterable containing each record in the response.

Create classes Event() similar to Cond()

class SourceViawarnCaAbAbt()

  • check_connection()

Set up a test to verify the connection between the connector and the API. This test should return two variables: the first one is a boolean that indicates the status of the connection, while the second one shows a log message if the connection fails.

return True, None

  • streams()
Set up the stream in the source that will be parsed.
return List of streams
