Python idiomatic SDK for the Palo Alto Networks Application Framework.

Project description

Palo Alto Networks Cloud Python SDK

Python idiomatic SDK for the Palo Alto Networks Application Framework.

The Palo Alto Networks Cloud Python SDK, or pancloud, was created to assist developers with programmatically interacting with the Palo Alto Networks Application Framework.

The primary goal is to provide full, low-level API coverage for the following Application Framework services:

  • Logging Service
  • Directory Sync Service
  • Event Service

The secondary goal is to provide coverage, in the form of helpers, for common tasks/operations.

  • Log/event pagination
  • OAuth 2.0 and token refreshing
  • More, coming soon!

Documentation Status Documentation Status pypi travis Documentation Status


Features

  • HTTP client wrapper for the popular Requests library with full access to its features.
  • Language bindings for Logging Service, Event Service and Directory-Sync Service.
  • Helper methods for performing common tasks, such as log/event pagination.
  • Credentials support for OAuth 2.0.
  • Library of example scripts illustrating how to leverage pancloud.

Status

The Palo Alto Networks Cloud Python SDK is considered beta at this time.

Installation

From PyPI:

$ pip install pancloud

Install From GitHub

Clone the repo:

$ git clone https://github.com/PaloAltoNetworks/pancloud.git

Use Documentation Status to install all dependencies and create a virtualenv for your project:

$ pipenv install

You can specify which python version to use by adding “–two” or “–three”:

$ pipenv --three install

Activate the pipenv shell:

$ pipenv shell

Obtaining and Using OAuth 2.0 Tokens

Work with your Developer Relations representative to register your application to receive the credentials needed to obtain an access_token. You’ll need a client_id, client_secret, and refresh_token. API Explorer may optionally be used to perform OAuth 2.0 and fetch tokens.

For more information visit the following RTD page: Credentials

Example

The following example assumes valid credentials are present:

$ ./logging_query.py

History

1.3.0 (2018-08-04)

  • Added support for custom read/write credentials path.
  • TinyDBStore fetch_credential() now returns None instead of empty str.
  • Fixed bug that caused _resolve_credential() to be executed an inefficient number of times.
  • Now updating HTTPClient headers instead of overriding them which previously broke HTTP persistence.
  • Added JMESPath isotime() function to summit.py which prints epoch.
