Connect to the Dynamics 365 / Dataverse Web API using interactive login

PyConnectDataverse

This Python program enables you to connect with the oData Web API for Dynamics, Power Apps and Dataverse.

Detailed instructions on how to get started can be found on andyhowes.co

This program can be used for:

• Securely accessing all functions of the OData Dataverse API OData Dataverse API with an authenticated Python session.
• Downloading Dynamics 365 data using Python for efficient analysis.
• Adding many-to-many relationship data to Dataverse.
• Automating tedious manual processes such as populating option sets and choices.
• Anything you can think of using the OData API and Python!

To write your own functions, use any of pcd python files as a template to get an authenticated session with the API and then make requests over HTTPs as needed. Basic operations can be found here.

An Azure Application with access to Dynamics is required to authorise the app. Authorisation details are stored in a env.json file an example is saved in example-env.json. Find instructions on andyhowes.co.

Further information can be found in these resources, which I used to develop the system.

pyconnectdataverse's Issues

Downloading a file from a Dataverse table

Hey, I use your code to query simple information from my Dataverse tables and summarize it in an HTML. Now I have the problem that I have a file column in my table and I try to download it in vain. Do you have any idea how this could work?

Thank you for sharing your work with everyone and thanks in advance :)
