Python: Data SDK

Fetch vehicle data using the Python Data SDK

Overview

Similar to the Data SDK in TypeScript, we also offer a Data SDK written in Python. The Python SDK is an open-source SDK built to facilitate developers in connecting to the API Services. The objective of the Python Data SDK is to handle actions that interact with the DIMO APIs.

Getting Started

To get started with the Python Data SDK, you should always start by defining which API your application is interested in using. Depending on what you want access to, you may need the following:

  1. developer_jwt: This uses the Developer License public credentials and the private key (API Key) of the app. A developer would get this JWT on the backend through Auth. This is sometimes referred to as access_token.

  2. vehicle_jwt: This is the second layer of security around getting vehicle data. A developer would first need end users to grand permissions to the Developer License, and then get this JWT through Token Exchange. This is sometimes referred to as privilege_token.

To learn more about the different JWTs and what they mean, visit the JWT section in Authentication.

Using the SDK

Installation

pip install dimo-python-sdk

Import

Import the SDK:

from dimo import DIMO

Initiate the SDK depending on the environment of your interest, we currently support both Production and Dev environments:

dimo = DIMO("Production")

# OR

dimo = DIMO("Dev")

Function Calls

Before you can get privileged data for vehicles via the Vehicle JWT, a user must have already shared vehicles with you (via your developer license). For more information on how to allow users to share their vehicle data with you, navigate to Login with DIMO.

Getting a Developer JWT

Use the client_id, domain (aka redirectUri), and api_key from your application that you configured in the Developer Console. 

# Call to get a Developer JWT
auth_header = dimo.auth.get_token(
    client_id = '<client_id>',
    domain = '<domain>',
    private_key = '<api_key>'
)

# Store the Developer JWT from the auth_header dictionary
dev_jwt = auth_header["access_token"]

Getting a Vehicle JWT

Your developer_jwt will be the dev_jwt from the previous section, for Getting a Developer JWT.

The privileges should be in list format – the below is just an example of privileges. You can read more about privileges under SACD Permissions Contract.

The token_id is the token_id of the vehicle you'll be requesting data for, e.g. getting Telemetry data.

# Call to get a Vehicle JWT
get_vehicle_jwt = dimo.token_exchange.exchange(
    developer_jwt = dev_jwt, 
    privileges=[1, 3, 4, 5],
    token_id=<token_id> 
    )

# Store the Vehicle JWT from the get_vehicle_jwt response
vehicle_jwt = get_vehicle_jwt['token']
