pbipy 2.0.3a0

A Python Library for interacting with the Power BI Rest API.

pbipy

pbipy is a Python Library for interacting with the Power BI Rest API. It aims to simplyify working with the Power BI Rest API and support programatic administration of Power BI in Python.

* Quick note: pbipy is currently in active development and not all API functionality is supported yet. See development progress below for what's been implemented and what's coming.

Installation

pip install pbipy

Or to install the latest development code:

pip install git+https://github.com/andrewvillazon/pbipy

Getting Started: Authentication

To use pbipy you'll first need to acquire a bearer_token.

How do I get a bearer_token?

To acquire a bearer_token you'll need to authenticate against your Registered Azure Power BI App. Registering is the first step in turning on the Power BI Rest API, so from this point on it's assumed your Power BI Rest API is up and running.

To authenticate against the Registered App, Microsoft provides the MSAL and azure-identity python libraries. These libraries support many different ways of acquiring a bearer_token.

Because there are multiple ways to acquire the token, pbipy assumes you'll do this in the way that suits, rather than directly handling authentication (of course, this might change in future).

This README doesn't cover Authentication in detail, however, these are some helpful resources that look at acquiring a bearer_token in the context of Power BI:

• Power BI REST API with Python and MSAL. Part II.
• Power BI REST API with Python Part III, azure-identity
• Monitoring Power BI using REST APIs from Python

The example below uses the msal library to to get a bearer_token.

Quickstart

Start by creating the PowerBI() client. All interactions with the Power BI Rest API go through this object.

import msal

from pbipy import PowerBI


#  msal auth setup
def acquire_bearer_token(username, password, azure_tenant_id, client_id, scopes):
    app = msal.PublicClientApplication(client_id, authority=azure_tenant_id)
    result = app.acquire_token_by_username_password(username, password, scopes)
    return result["access_token"]


bearer_token = acquire_bearer_token(
    username="your-username",
    password="your-password",
    azure_tenant_id="https://login.microsoftonline.com/your-azure-tenant-id",
    client_id="your-pbi-client-id",
    scopes=["https://analysis.windows.net/powerbi/api/.default"],
)

# Create Client
pbi = PowerBI(bearer_token)

Functionality

To interact with the API, simply call the relevant method from the client.

# Grab the datasets from a workspace

pbi.datasets(group="f089354e-8366-4e18-aea3-4cb4a3a50b48")

pbipy converts API responses into regular Python objects, with snake case included! 🐍🐍

sales = pbi.dataset("cfafbeb1-8037-4d0c-896e-a46fb27ff229")

print(type(sales))
print(hasattr(sales, "configured_by"))

# <class 'pbipy.resources.Dataset'>
# True

If you need to access the raw json representation, this is supported to.

sales = pbi.dataset("cfafbeb1-8037-4d0c-896e-a46fb27ff229")

print(sales.raw)

# {
#   "id": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
#   "name": "SalesMarketing",
#   "addRowsAPIEnabled": False,
#   "configuredBy": "[e-mail]",
#   ...
# }

Examples

Datasets

Get a dataset

sales = pbi.dataset(id="cfafbeb1-8037-4d0c-896e-a46fb27ff229")
print(sales)

# <Dataset id='cfafbeb1-8037-4d0c-896e-a46fb27ff229', name='SalesMarketing', ...>

Get a list of Datasets in a Group (aka Workspace)

datasets = pbi.datasets(group="f089354e-8366-4e18-aea3-4cb4a3a50b48")

for dataset in datasets:
    print(dataset)

# <Dataset id='cfafbeb1-8037-4d0c-896e-a46fb27ff229', ...>
# <Dataset id='f7fc6510-e151-42a3-850b-d0805a391db0', ...>

Refresh History of a Dataset

dataset = pbi.dataset(
    "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
    group="f089354e-8366-4e18-aea3-4cb4a3a50b48",
)

refresh_history = dataset.refresh_history()

for entry in refresh_history:
    print(entry)

# {"refreshType":"ViaApi", "startTime":"2017-06-13T09:25:43.153Z", "status": "Completed" ...}

Add user permissions to a Dataset

sales_ds = pbi.dataset( "cfafbeb1-8037-4d0c-896e-a46fb27ff229")

# Give John 'Read' access on the dataset
sales_ds.add_user("[e-mail]", "User", "Read")

Execute a DAX Query

dataset = pbi.dataset( "cfafbeb1-8037-4d0c-896e-a46fb27ff229")

dxq_result = dataset.execute_queries("EVALUATE VALUES(MyTable)")
print(dxq_result)

# {
#   "results": [
#     {
#       "tables": [
#         {
#           "rows": [
#             {
#               "MyTable[Year]": 2010,
#               "MyTable[Quarter]": "Q1"
#             },
# ...
# }

Power BI Rest API Operations

pbipy methods wrap around the Operations described in the Power BI Rest API Reference:

Power BI REST APIs for embedded analytics and automation - Power BI REST API

Development Progress

pbipy is in the early stages of development so expect a few features to be missing. The aim is to cover off most of the core stuff like Datasets, Workspaces (Groups), Reports, Apps, etc., and the rest later on. Check back regularly to see what's been added or still in the pipeline.

PowerBI Component	Progress	Notes
Datasets	Done
Groups (Workspaces)	Doing
Reports	Next
Apps	Todo
Dataflows	Todo
Dashboards	Todo
Everything else	Backlog

Contributing

Contributions such as bug reports, fixes, documentation or docstrings, enhancements, and ideas are welcome. pbipy uses github to host code, track issues, record feature requests, and accept pull requests.

A contributing.md is in the works, but in the meantime below is a general guide.

Making a contribution

Pull requests are the best way to make a contribution to the code:

1. Fork the repo and create your branch from master.
2. If you've added code that should be tested, add tests.
3. Add docstrings.
4. Ensure the test suite passes.
5. Format your code (pbipy uses black.
6. Issue that pull request!

Reporting a bug

Great Bug Reports tend to have:

• A quick summary and/or background
• Steps to reproduce. Be specific! Give sample code if you can.
• What you expected would happen
• What actually happens
• Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)

Acknowledgements

The design of this library was heavily inspired by (basically copied) the pycontribs/jira library. It also borrows elements of cmberryay's pypowerbi wrapper.

Thank You to all the contributors to these libraries for the great examples of what an API Wrapper can be.
